Off-board Relays

D8129 OctoRelay

The D8129 OctoRelay allows you to add relay outputs to your system in groups of eight. Up to 128 OctoRelay outputs (relay numbers 1 to 128) can be added to your system using 16 OctoRelays. Review the Power Outputs section of this manual to be sure you provide enough power for the OctoRelays and other powered devices you wish to connect to your system.

OctoRelays for relay numbers 1 - 64 connect to ZONEX 1, terminal 28 on the D9112. OctoRelays for relay numbers 65-128 connect to ZONEX 2, terminal 26 on the D9112. See Figure 17.

You can assign alarm output, auxiliary relay, sensor reset, arming status, point status, alarm memory, or remote functions (Command 54) to the OctoRelay outputs individually. See Relay Parameters in the D9112 Program Entry Guide (74-06145-000) for programming details.

D8129 restricted for fire systems: The D8129 relay outputs are not supervised and can not be used in fire or combined fire/burglary installations for primary indicating devices.

Configuring the D8129 OctoRelay

Five switches on the OctoRelay determine the relay numbers for the eight relay outputs. Table 3 shows the switch settings.

Warning: Relay outputs may activate while setting the OctoRelay switches or programming the panel. You may wish to disconnect equipment connected to relay outputs while performing these functions.

Relay Outputs

Each OctoRelay output provides a Form C dry contact rated for 1.0A at 12 VDC. Normally-open, common, and normally-closed terminals are available for each relay output. When an individual output is activated, there is continuity between the normally- open and common terminals. When the output is not activated, there is continuity between the normally-closed and common terminals.
