Strata CT I&M Manual October 2000
External BGM Installation
The external BGM options are closely associated with the external paging options. See
“External Page Options” on Page 6-28 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 240VAC power
source.
Note See the Strata CT 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 6-7, and 6-8 .)
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).
