Connecting the C1169 Lamp Driver board outputs
The Lamp Driver board is designed to provide extra load drive capability for Omni8C and 16C where high
power lamps need to be driven typically where old mimic panel or alarm beacons are utilized.
The Lamp Driver board is fitted into one of the Repeat Outputs Slots on the Omni8 or 16. It has 16
Channels connected via detachable terminals which can be removed with the wiring.
Each output channel can deliver 250mA to a lamp using an externally connected 24Vdc power supply.
The connection uses a 24 V common on Terminal 1 and 2 with each lamp having a dedicated output from
terminals 3 to 18. The Lamp return going back to the external supply negative.

Connecting the Inhibit Input
By switching this input to 0 Volts of the 24Volt Supply (terminal C-2), all new alarms are prevented from
occurring. Repeat outputs when set to follow inputs will be unaffected and input status can still be
monitored via the serial link.
NOTE: The Omni8P does not have this inhibit input.

Connecting the optional Input Repeat Relay Contacts (Model C1425)
The Omni8/16C may be fitted with optional Input Repeat Relay boards. These boards provide a single
normally open contact as a repeat of each alarm input in the unit. This may be used for connecting to
other equipment such as sequence-of-event recorders or data-loggers.
The contact will be closed when the corresponding input is the normal condition, and will be open when
the input is in the alarm condition. This is independent of whether the input is set to be normally open or
normally closed. Should a single C1425 be utilised in either slots E or F, relay outputs will be mapped to
Inputs 1 to 8 only.
