9.0 Relay Parameters

Relays provide basic alarm system functions (such as

Bell Output and Reset Sensors) as well as a number

of more advanced functions typically used in

association with system annunciation devices.

Up to three on-board voltage-output relays can be

installed on the D9112 circuit board. (see the D9112

Operation and Installation Manual for instructions).

The D9112 can also control up to 128 dry contact

form “C” relays when optional D8129 OctoRelay

Modules are installed.

One relay is provided with the D9112 to provide a

+12 VDC Alarm Bell output from the D9112

terminal 6 (Relay A).

Two additional optional relay sockets are provided

with the D9112. The D9112 provides a +12 VDC

Alternate Alarm output from terminal 7 (Relay B),

and a +12 VDC Switched Aux Power output from

terminal 8 (Relay C). Optional relay sockets require

Bosch Security Systems D136 Relays.

If relay activity is reported to the receiver (see Phone

Routing), on-board relays are reported as follows: A

= 253, B = 254, C = 255.

Up to sixteen D8129 OctoRelay Modules can be

connected to the D9112 to provide 128 dry contact

form “C” relays. You can set DIP switches on each

D8129 to use a group of eight numbered relays as

shown in the D9112 Operation and Installation Manual.

Check relay status after reprogramming or

resetting the panel. All relays are turned off

after the panel is reset. Certain relay

functions are checked by the panel each

minute and resume the correct state after

the reset. Other relays must be manually set

to the correct state (using Cmd 54).
