997-492-000-6, Issue 6 July 201126 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual 7.2 Panel Options - A Four user-configurable panel options are available: a. Enable/Disable Engineering Mute b. Enable/Disable Commissioning Mode c. ACCEPT pushbutton access level d. LAMP TEST pushbutton access level. e. Delay Lights DISABLEMENT LED 7.2.1 Engineering Mute The operation of the panel’s buzzer can be changed so that it operates only occasionally with a Fire state, fault condition or during any active configured first stage delays. This can be selected independently of Commissioning Mode. The default is Engineering Mute disabled. 7.2.2 Commissioning Mode The panel can be put in Commissioning Mode to assist the commissioning process. In this mode, most faults are indicated after 4 secs instead of the normal 20 secs delay to aid fault finding. Commissioning Mode times-out automatically 60 secs after the cover is replaced. Selection of commissioning Mode automatically selects the Engineering Mute function. 7.2.3 ACCEPT Pushbutton Access Level The ACCEPT pushbutton can be configured to operate at access Level 1 or 2. The default operation is access Level 2. 7.2.4 LAMP TEST Access Level The LAMP TEST pushbutton can be configured to operate at access Level 1 or 2. The default operation is access Level 2. 7.2.5 Delay Lights DISABLEMENT LED EN 54-2 and ISO 7240 Annex E acknowledges that delays may be permanently configured in the normal mode of operation of the equipment, (e.g. day mode) and in such cases there is no need for a disablement indication. Use this option when the DISABLEMENT LED is required to indicate any configured delays. 7.3 Panel Options - B The following options are selectable: a. Non-latched faults b. Pulse Fire Routing outputs c. FBF Fire Routing disable - forces off d. Re-sound - new zone in alarm e. Mains fault delay. 7.3.1 Non-latched Faults When enabled, this option allows faults and fault indications to clear automatically. The buzzer can still be silenced while a fault is shown on the panel (it will resound if the fault reoccurs). By default the option is disabled and fault indications require manual intervention to clear. EN 54-2 & ISO 7240-2: Annex E Does not require delay indicated as a disablement.
997-492-000-6, Issue 6July 2011 27 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual Non-latching only affects the following fault conditions: a. Zone Faults b. Earth Fault c. Power Supply Fault d. Sounder Fault e. Fire Output Fault f. Fault Output Fault g. Auxiliary Supply Fault. Note:System Fault remains latching at all times. 7.3.2 Pulse Fire Routing Outputs When this option is selected the fire routing ouput is activated for a period of 5 secs only (pulsed). Continuous activation of the routing output is the default. 7.3.3 FBF Fire Routing Disable - Forces Off VdS requirement only. 7.3.4 Re-sound - New Zone in Alarm By default, after the panel has received a fire event and the sounders have been silenced using the SOUNDERS START/STOP pushbutton, a new fire event, but in another zone, will activate the sounder outputs again. This option allows the configuration of sounder outputs to ignore any new zones in fire after the sounders have been silenced. 7.3.5 Mains Fault Delay By default, a mains fault is indicated within 10 seconds. This option allows the delay to be extended to 30, 60 or 90 minutes. The 60 minute and 90 minute options do not comply with EN 54 (see information at left). Note:The Non-latched faults and Mains fault delay options can be used together. For example, if the delay is set to 30 minutes then the fault is indicated after this time. The indication is removed automatically 10 seconds after the fault is cleared. 7.4 System Options The following options are selectable: a. Clear Checksum b. Select Default Configuration 7.4.1 Clear Checksum Use this selection to clear user configuration checksum faults. 7.4.2 Select Default Configuration This enables the panel to be returned to the factory- configured state. When System LED 2 is lit the panel is in the factory-configured state. EN 54-4: 5.4 A mains fault MUST be indicated within 30 minutes. ISO 7240-4 : 5.4 A mains fault MUST be indicated within 100 seconds. ISO 7240 !ISO7240 !
997-492-000-6, Issue 6 July 201128 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual 7.5 Fire Zone Input Type Fire input zones can be configured as follows: a. Latching/non-latching alarms b. Alarm or for short-circuit operation c. Auto or manual operation mode d. Coincident-alarm or separate-alarm detection e. Setting a Sprinkler Verification Time. f. EOL Device Type. 7.5.1 Latching/Non-latching Alarms A detection zone can be configured as latching or non- latching. When selected as latching, if the panel enters the fire (or fault) state this condition will remain active until the panel is reset. When selected as non-latching, the panel state returns to normal once the input condition has been cleared. The default is latching. 7.5.2 Alarm or Short-circuit Operation The panel can be configured to respond to a short-circuit input on a zone as a fire or fault condition. The default is fault indication. Caution: You will contravene the requirements of EN 54-2 if you configure short-circuit as a fire condition. For guidance, refer to appropriate local fire standards. 7.5.3 Auto/ Manual Zones The panel has the following factory-configured default: a. Odd-numbered zones - manual zone, i.e. no delay to activation of outputs, used with MCPs. Manual zones will always cause immediate entry into the Fire state. b. Even-numbered zones - auto. detection, i.e. if configured for day-time delay strategy, outputs will be delayed as per the delay strategy. Note: If no delay strategy is being used (default panel setting) this operation has no effect. Any zone can be configured as manual or auto action. 7.5.4 Coincidence Detection The panel will, by default, indicate a fire condition when a single device on a single zone goes into alarm. The panel can be configured so that to enter a full fire condition, two zones must be in the fire state. Coincidence detection is only supported for pairs of zones, i.e. zone 1 concident with 2, zone 3 coincident with 4, etc. When configured, upon the first zone going into fire the respective zonal fire indicator illuminates, the panel enters the alert state but the general fire LED does not light. Note: Zone pairs set for coincidence detection are forced to function as auto zones. On the second fire alarm zone the standard fire sequence will be followed for both input zones. EN 54-2 : 8.2.4a) & ISO 7240-2 : 9.2.4a) The panel must indicate a fault condition for a short circuit. ! EN54 ISO 7240! EN54 ISO 7240 EN 54-2: & ISO 7240-2: 7.6 1. Configuring a local detection zone as non- latching contravenes the requirements of EN54 and ISO 7240. 2. Reset from an alarm state must be a manual operation at access Level 2. ! EN54 ISO 7240!

997-492-000-6, Issue 6July 2011 29 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual 7.5.5 Sprinkler Verification Time A 2 sec. verification time is applied to all inputs to reduce the occurrence of false indications of alarm due to transient phenomena. When monitoring an input from a sprinkler system it may be necessary to configure a sprinkler verification delay. This is an exceptional situation and will require the approval of a fire officer. 7.5.6 EOL Device Type Use this option to change the default EOL device type from a capacitor to a resistor when the panel is used for retrofit installations. Note: Failure to do this on retrofit installations may cause the panel to enter the Fire state, with consequent operation of the sounders. 7.6 Sounder Output Type/ Delay The two sounder circuits and two optional relay circuits, if fitted, are each configurable as one of the following: a. Sounder output b. Fire routing output c. Fault output. d. Local Alarm Output. Up to two optional, 8-way Relay PCB(s) can be fitted. Each PCB can be independently configured to provide one of the following functions: e. Repeat Zonal Output f. Coincident Zonal Output g. Repeat Zonal Output (zones 1-4) and Shop Interface Outputs h. Inputs and Shop Interface Outputs. Up to two optional, 4-way Sounder PCB(s) can be fitted. Each PCB can be independently configured to provide monitored sounder, fire or fault routing output. EN 54 and ISO 7240-2 and local installation guidelines impose requirements on the application of outputs. Please consider the following when configuring the different output types available on this CIE: i One output on the panel must be configured as a fire output, (EN 54-2 & ISO 7240-2: 7.7.1). This may be an unmonitored relay output. ii One output on the panel must be configured as a fault output. (EN 54-2: 8.8 and ISO 7240-2: 9.8). This may be an unmonitored relay output. iii If an EN 54-2 or ISO 7240-2, 7.8 monitored sounder output is required an unmonitored relay is not suitable, use a monitored sounder output (either PSU PCB or 4-way sounder output PCB). iv If an EN 54-2 or ISO 7240-2, 7.9 monitored fire alarm routing output is required an unmonitored relay is not suitable, use a monitored sounder output (either PSU PCB or 4-way sounder output PCB). v) If an EN54-2 or ISO 7240-2, 7.10 monitored fire protection output is required use the optional 4-way EN 54-2: & ISO 7240-2: 7.1.3 The panel must respond to an input within 10 secs. !

997-492-000-6, Issue 6 July 201130 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual sounder output PCB, NFS-SST(English PN: 020-769- 001) or NFS8V-SST (German PN: 020-769) Display Boxes and Routing Termination kit (020-773). vi If an EN 54-2 or ISO 7240-2, 8.9 monitored fault routing output is required both relay and PSU PCB sounder outputs are unmonitored in this mode. For this application use the optional 4-way sounder output PCB. vii Note: PSU PCB sounder circuits do not comply with EN 54-13 partial-open-, partial-short-circuit requirements. For this application use the optional 4- way sounder output PCB. 7.6.1 Select Output Select Sounder 1, Sounder 2, or if the 2-way Relay PCB is fitted, Relay 1 or Relay 2. The default selection is Sounder 1. Press to select another output. 7.6.2 Select Type Having selected the appropriate output circuit now select one of the following: Sounder, Fire Routing Output, Fault output, Local Alarm Output or Pulsing Sounder Output. The default type for Sounder circuits 1 and 2 is Sounder. Press to select an alternative type. Notes: 1 The Local Alarm Output does not activate with non- latched zones (assumes non-latched zones are from external panels). 2 The pulsing option will activate the selected sounder/relay outputs as follows: one second ON / one second OFF. 7.6.3 Select Delay These outputs can be configured as part of a strategy to delay the operation of sounder and/ or fire routing outputs during daytime operation. Each sounder/ fire routing/ fault routing/ lo cal alarm output can be configured with a two-stage delay (see Section 7.8 Primary and Secondary Delays ). Once configured the DELAY ON/OFF pushbutton or a Digital Input are used to enable the delay to outputs. This panel state is confirmed by the illumination of the DELAY ON LED (default configuration). If required, the panel may also be configured to light the DISABLEMENT LED when the delay mode is active (refer to ‘Panel Options - A’ of the configuration menu located at the back of this manual). 7.7 Digital Inputs Two digital input circuits are provided for connection to ancillary equipment, if required. Each circuit can be configured to provide one of the following input actions: a. Class change (default) b. Alert c. Evacuate d. Delay Mode (default) e. Reset f. Fire transmission confirmed return signal (latched or non-latched) Sounder output types ‘sounder’ and ‘pulsed’ must not be mixed on the same installation to avoidconfusion of the evacuation signal. EN 54-2 & ISO 7240-2 Level 2 Keyswitch access MUST be used with these inputs. ! EN54 ISO 7240! EN54 ISO 7240 EN 54-13: 5.3.4 Installations designed to meet EN 54-13 require partial short and partial open fault warning.
997-492-000-6, Issue 6July 2011 31 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual g. Fault transmission failed return signal. Class Change: When a class change digital input is activated, all outputs configured as sounders will be activated until the input condition is removed. Alert: When an alert digital input is activated, all outputs configured as sounders and the internal buzzer start pulsing. The sounders and internal buzzer remain pulsing until the digital input is deactivated. Alert operation will override class change and fault conditions, but not the alarm condition. Note:If the sounder output is configured as type ‘pulsed’ then an alert input will cause the sounder outputs and internal buzzer to turn on with a steady tone. Evacuate: When an evacuate digital input is activated, a general evacuate is initiated, i.e. all the bells activate, until the input condition is removed. Note: If the sounder output is configured as type ‘pulsed’ then an evacuate input will cause the sounder outputs and internal buzzer to pulse. Delay Mode: This allows external control of delays to outputs. It can be used to delay activation of outputs during the day and so this use is commonly known as Day Mode. When this input is active, delays can still be cancelled using the ‘Delays On/Off’ button. Reset: This digital input can be used to return the panel to normal operation after the occurrence of an event, such as an alarm or fault. Faults are latching and a reset cannot return the panel to normal until the condition causing the fault has been remedied. Fire Transmission confirmed return signal: This type of digital input provides the ability to confirm the activation of the Fire Routing Output. Selection of either a latched or non-latched activation signal is available. Fault Transmission failed return signal: This type of digital input provides the ability to route Fault Routing Output faults back to the panel. It is assumed that the external equipment will provide the necessary fault monitoring of the routing output and provide feedback to the panel. 7.7.1 Select Input Select Digital Input circuit 1 or 2. The default selection is input 1. Press push-button to select the other output. 7.7.2 Set Type Digital input 1 is configured, by default, as a Delay Mode input. Digital input 2 is configured, by default, as a Class Change input. Press push-button to select another type.
997-492-000-6, Issue 6 July 201132 EN 54 & ISO 7240 2-8 Zone Conventional Fire Panel - Installation & Configuration Manual 7.8 Primary and Secondary Delays A day-time delay strategy can be implemented, if required, which comprises two user-configurable delay periods to allow a fire search to take place. These delay periods are referred to as primary and secondary. On an auto detection zone, every fire state places the panel in a full alarm, hold- off state until the indicated fire event has either: a. Been verified as true after the search and then manually-terminated (at the panel or by operating an MCP), or b. The primary delay period expires, thereby automatically operating the configured outputs (e.g. sounders). If the ACCEPT pushbutton is pressed during the primary delay period the delay to outputs is extended by the length of the configured secondary delay. The maximum total duration of a configured delay to outputs is 10 minutes, even if the sum of the configured primary and secondary delays exceeds this limit. Once the ten-minute delay period has expired the outputs will be activated automatically. 7.8.1 Select Primary Delay Time Specify the first stage of the delay to outputs. The default is 30 secs. Press the push-button to specify another primary delay period up to 120 secs in 30 sec increments. 7.8.2 Delay toTransmission Device Activation of the transmission device output may be subject to a delay. Press the push-button to toggle the delayed/immediate action. The default condition is ‘delayed’. 7.8.3 Select Secondary Delay Time Specify the second stage of the delay to outputs. The default is 1 minute. Press the push-button to specify another secondary delay period up to 10 minutes in 1 min increments. 7.8.4 Two-zone Override Delay Delays to outputs are overridden when a second zone goes into fire. This default can be changed so that a second zone going into fire does not override an active delay.
