To install the MOH/BGM as BGM
1. Ensure that the MOH option is installed in accordance with “To install the MOH option” on 
Page 10-4 (see Figure 10-2).
2. The output of the RCTU page/BGM control is applied through the backplane to the output 
select switch (SW4) on the PIOU or PEPU. Set the SW4 switch to either SPO or SPI, as 
required:
©SPO – Directs external page and non-amplified BGM to the HESB or external amplifier 
(pins 13 and 38).
©SPI – Directs external page and BGM through the on-board 3-watt amplifier to the 
external speaker output (pins 25 and 50).
NoteThe PIOUS provides non-amplified BGM/page output only (SPT and SPR). See Figure 
10-8.
3. When using an HESB or external amplifier for paging/BGM, adjust volume using the HESB 
or amplifier volume control.
4. When using the internal amplifier for paging/BGM, adjust the volume using the volume 
control (VR1) on the PIOU/PEPU PCB.
Alternate BGM Source Installation
A BGM source can be connected to a station PCB (QSTU2, KSTU2, RSTU2/PSTU, RDSU, 
PEKU, or PESU) to send music to all electronic/digital telephone speakers and to the external page 
system via a PIOU, PIOUS, or PEPU. The BGM source is separate from the MOH source 
connected to the RCTU PCB. An isolation transformer is needed to connect a music source to one 
of the above standard telephone circuits (see Figure 10-4).
ä
To connect the BGM source to the QSTU2, KSTU2, RSTU2/PSTU, RDSU, PEKU or PESU
See Figures 10-4~10-6 and follow these steps:
1. Access Program 10-2. If the BGM source is connected to circuit 3 on a PEKU, set LED 09 to 
ON. If the source is connected to circuit 8 on a PESU, set LED 10 to ON. If connecting BGM 
to QSTU2, KSTU2, RSTU2, RDSU or PSTU, LED 09 and 10 should be OFF.
2. Using Program 19, identify (assign) the BGM slot.
3. If connecting the BGM source to a PEKU or PESU: Connect the PEKU tip and ring of circuit 
03 to the 600 ohms or 8 ohms output of the BGM source or connect the BGM output to circuit 
8 of a PESU.
...or
If connecting the BGM source to a QSTU2, KSTU2, RSTU2/PSTU or RDSU: Connect circuit 
2 of the RSTU2/PSTU or RDSU to a customer-supplied isolation transformer and BGM 
source.
NoteThe isolation transformer protects the BGM source from potentially damaging QSTU2, 
KSTU2, RSTU2/PSTU or RDSU voltage. Some music sources which are designed for 
telephone system applications may have this protection built-in and do not require the 
transformer. (Consult the documentation provided with the music source.)
4. If the BGM source is connected to either a W5 on the PEKU or W7 on the PESU PCB, cut the 
strap. There is no strap to cut on the QSTU2/KSTU2, RSTU2/PSTU or RDSU.

5.Using the BGM source’s volume control, adjust the BGM volume to the desired level while 
listening to BGM via a telephone speaker and/or the external page speakers. When BGM is 
sent to external speakers via a PIOU or PIOUS or PEPU PCB, use the external amplifier 
volume control to balance the BGM and page volume levels.
External BGM Installation
The external BGM options are closely associated with the external paging options. See “External 
Page Options” on Page 10-26 for external paging amplifier installation.
Relay Control Options and Door Lock Control
Two relays are provided on the PIOU, PIOUS, and PEPU PCBs to control the operation of 
peripheral equipment: 
©External Page/Door Lock Relay
©Night Transfer/Music-on-Hold Relay
NoteOnly the PIOU/PIOUS/PEPU with the lowest Program 03 code (41, 42, or 43) will 
provide the relay control function.
Each relay can be configured to provide one of two possible control functions and as normally 
open (MAKE) or closed (BREAK). Electrical specifications for the relay contacts are as follows:
Voltage: 24VDC maximum
Current: 1 amp maximum
CAUTION!To prevent relay damage, do not connect relays directly to 120VAC power 
source.
NoteSee the Strata DK Programming Manual, as necessary, when instructed to program the 
PIOU, PIOUS, or PEPU in the following paragraphs.
External Page/Door Lock Relay Options (PIOU, PIOUS, or PEPU)
The PIOU, PIOUS, or PEPU PCB may be programmed for either the external page function or the 
door lock control function. (See Figures 10-7 and 10-8.)
When configured in Program 77-1 for the external page function, the relay controls an external 
music source connected to the PIOU, PIOUS or PEPU to provide BGM over external speakers. 
When a paging announcement is made over the external speakers, the external page relay mutes 
the BGM. 
When configured in Program 77-1 for the door lock control function, the relay controls an external 
door lock. When a door lock button at a digital or electronic telephone is pressed, the door lock 
control relay unlocks the door for three or six seconds, as specified in Program 77-1 (LED 20).
