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 12-26 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
Note
Only 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.
Note
See 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 12-7 and 12-8 .)
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).
