The transformer is connected to the 24VAC terminals. The battery is connected using the battery cable
connected to the board.
Each Expansion Enclosure MUST be grounded in ONE of two possible ways:
1. Earth ground each Expansion Enclosure to the same earth ground as the controller.
- OR -
2. Connect the Earth Ground terminal of each Expansion Enclosure to the Earth Ground terminal of the
controller using a separate conductor. In this case, do not connect the Expansion Enclosure to a
separate earth ground.
The controller and Expansion Enclosure(s) grounds must be connected together or to the same earth
ground to prevent any current from flowing through the RS-485 data bus (connections A and B). If
grounding is not as specified here, there is the possibility that the controller and Expansion Enclosure
may lose communications, resulting in all zones in the Expansion Enclosure going into trouble or alarm,
as required by UL.
24 HOUR BATTERY BACKUP OPTION
For extended battery backup time, a second 12V 7Ah battery can be installed - See Figure 5 - “24 Hour
Standby Connections”. Maximum total current load is reduced to 0.4 amps.
ADDRESS SETTINGS
DIP switch "S1" is used to set the communications address for the Expansion Enclosure. Up to four
Expansion Enclosures can be addressed and used with OmniPro and up to eight Expansion Enclosures
can be addressed and used with OmniPro II.
Expansion Enclosures 1-4 are addressed by setting the corresponding switch to on and all others off.
For example, to set the address for the first Expansion Enclosure, set switch S1-1 on and all others off;
for the second, set switch S1-2 on and all others off. The third and fourth are addressed similarly, using
S1-3 and S1-4, respectively.
Expansion Enclosures 5-8 are addressed by using the sum of all switches set to on. For example, to set
the address for the fifth Expansion Enclosure, set switch S1-1 and S1-4 on and all others off. To address
the sixth Expansion Enclosure, set S1-2 and S1-4 on and all others off. To address the seventh
Expansion Enclosure, set S1-3 and S1-4 on and all others off. To address the eighth Expansion
Enclosure, set S1-1, S1-3, and S1-4 on and all others off.
Multiple switch combinations are possible for certain addresses. For example, to set the address for the
fifth Expansion Enclosure, you can set S1-1 and S1-4 on and all others off
or you can set S1-2 and S1-3
and all others off.
