Installing External Paging Relay Control
You can alternately use the 2 Door Box relays to control an External Pag-
ing amplifier. Connecting an Analog Door Box on page 59 shows you the
location of the Door Box relays. Note that if you use a relay for External
Paging Control, you cannot also use it for Door Box strike control.
!! Important !!
Be sure the devices connected to the system’s relay contacts are compatible
with the following specifications.
Contact Configuration. . . . . . . . . . . . . . . Normally Open
Maximum Load. . . . . . . . . . . . . . . . . . . . 0.5A @ 120 VAC
1 A @ 24 VDC
Maximum Initial Contact Resistance . . . 100 mOhms
1. If you are using the Door 1 relays, connect the BLK and YEL lugs on the
Door Box 1 modular jack to the relay that controls the External Paging
system.
2. If you are using the Door 2 relays, connect the BLK and YEL lugs on the
Door Box 2 modular jack to the relay that controls the External Paging
system.
Keep in mind that the following system programs must be set for relays.

Program 0201: Door 1 Relay
Assign the Door 1 Relay for External Paging control, enter 2.
➻
Program 0201: Page Zone (Door 1 Relay)
Enter the Page Zone (1-7) that should activate the Door 1 relay. Note
that Zone 1 and All Call Paging announcements broadcast from the
External Paging output.
