Emergency Shutdown Wiring:
To connect your fi re alarm or emergency management system
to the RPC, follow these steps.
1. From the fi re alarm unit or latching Emergency Shutoff
switch, wire the Normally Open (NO) contacts to the IN and
24V positions of Digital I/O Port #1 on the Controller.
2. If a remote status indicator is used, ensure that the positive
terminal is wired to the 24V position and the negative
terminal is wired to the OUT position of Digital I/O Port #1.
3. When the Normally Open contacts are closed, the status
indicator will immediately light and all breakers that have
been selected for E. Shutoff should cycle to OFF.
4. When the contacts are released, the status indicator will
extinguish and all breakers that were ON when E. Shutoff
was activated should return to the ON state.
See Chapter 5 to confi gure the software for emergency
