RELAYS

Relays - External Page, Door Box, General Purpose (Figure 4-15, Figure 4-55)

Two external dry contact relays are available when a 2PGDAD is installed which can be used to activate ancil-
lary devices (i.e. door unlock devices). The CPU provides one relay - this relay is number 0 in programming. In
programming, the 2PGDAD module relays are numbered 1-8. Each Door Box/external page circuit provides a
dry relay contact.

Connecting to the CPU (External MOH, BGM, General Purpose Relays Only) :
Connect an RJ61 modular line cord from the CN23 connector on the CPU to the appropriate loca-
tion on the extension cross-connect block. Use the pin-out information for the CPU's connector.

• Pins 4 and 5: External Music on Hold Input, Input Impedance 600 ohm/1 kHz
• Pins 3 and 6: Relay = DC Max. 24 VDC, 0.5A - AC Max. 120VAC, 0.25A
Connect the two-conductor station cable from the cross-connect block to the external relay.
Install bridging clips as required.
Program 10-21-01 sets the relay switch on the CPU. If set to '3" (General Purpose Relay), service
code 880+0 toggles the relay open or closed.
The service codes indicated are the default codes. Refer to Program 11-12-50 to redefine the
code as needed.
Connecting to the 2PGDAD Module:
Make sure the jumper in the 2PGDAD module for the channel is set correctly. (Refer to Figure 4-4
JUMPER SETTINGS on page 4-3).
If a line cord was not previously connected to the 2PGDAD, complete Steps 3-6. Otherwise, skip to
Step 7.
Install a modular jack for each 2PGDAD module. For each module, run one-pair 24 AWG station
cable from the cross-connect block to a modular jack. Ground the unused pair.
Terminate the extension leads to GRN/RED of the modular jack. Terminate the unused leads to the
jack.
Install bridging clips as required.
Plug a modular line cord from the mod jack to the CN1 connector on the 2PGDAD module.
Connect the two-conductor station cable from the CN5 connectors within the 2PGDAD module to
the external relay.
