The sounder is a piezo-electric sounder that pulses for fire alarms and generates a two-tone sound for
burglary and audible panic alarms.
The keypad contains two LEDs that indicate the status of the system as follows:
Green Lights when the system is ready to arm (no zone faults are present).
Red Lights when the system is armed.

key entries). Function keys must be held down for at least 2 seconds to activate an alarm.
(Check with your installer for the programmed function of these keys.)
