Relay Control Options and Door Lock Control

The Base Unit provides one relay and two relays are provided on the PIOU, PIOUS, and
PEPU PCBs installed in the expansion cabinet to control the operation of peripheral
equipment. For the Base Unit relay options,
relays provided on the PIOU, PIOUS, PEPU PCBs are as follows:
External Page/Door Lock Relay
Night Transfer/Music-on-Hold Relay
Note
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:
CAUTION!
Note
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.
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).
Configure PIOU, PIOUS or PEPU for External Page Mute Option
1. Set Program 77-1 LED 07 to OFF to configure the PIOU, PIOUS, or PEPU PCB for the
external page function.
2. If using a PIOU or PEPU, set the jumper plug P10 on the PIOU or PEPU jumper plug to
the MAKE or BREAK position as required:
6-10
Refer to the Strata DK40 Programming Manual or DK Library CD-Rom for more details.
Only the PIOU/PIOUS/PEPU with the lowest Program 03 code (41 or 42) will
provide the relay control function.
Voltage: 24VDC maximum
Current: 1 amp maximum
To prevent relay damage, do not connect relays directly to 240VAC power
source.
Refer to the Strata DK40 Programming Manual, as necessary, when instructed to
program the PIOU, PIOUS, or PEPU in the following paragraphs.
MAKE–Shorts the normally open contacts (pins 7 and 32) when external page is
