Figure 2-7. Auxiliary Relay Board Wiring Diagram
Wiring Remote Enclosure with Auxiliary Relay
Refer to the "Wiring the Remote Enclosure" section to run the cable between the local and remote enclosures. In
most cases the auxiliary relay board is in the same enclosure as the control circuit. Both boards are mounted on the
same panel and have been wired together at the factory. This configuration can be ordered without an enclosure
which can be supplied by the customer.
The alarm connections are made at the auxiliary relay board where each alarm is driving a DPDT relay.
Caution: Do not connect any loads to the control circuit socket. Damage will occur to the control circuit if the
alarm circuit is energized.
Be sure the correct relay board has been ordered for the correct output. See the following paragraph.
This configuration uses a control circuit that provides a switching voltage signal instead of relay contacts. The
switch voltage is wired from the control circuit socket to the auxiliary relay board actuating the relays.
The auxiliary relay board has several relay options that can be ordered. The options are as follows:
• Dry to 2 amps at 115 Vac or 28Vdc, Dry to 1 amp at 230 Vac (relay is enclosed in a plastic sealed cover).
• 100mA to 10mA at 115 Vac or 28Vdc, 50mA to 3 amps at 230 Vac (relay is enclosed in a plastic sealed cover).
• Dry to 0.5 amps at 115 Vac, hermetically sealed relay.
