Notes
•
The NAC/AUX circuit must be configured for AUX operation using the DIP switches. See
“Setting the DIP switches” for details.
• CT2 modules must be wired and programmed on the Signature controller for proper
operation.
• AC power loss causes circuit 2 on the CT2 to report a trouble to the control panel (see panel
programming). All other BPS troubles cause circuit 1 (Sense 1) on the CT2 to report a trouble
to the panel.
Common trouble relay wiring
The BPS has a Form C common trouble relay that provides a normally open and
normally closed contact. The trouble relay switches under any trouble condition
when DIP switch SW2-6 is off. When the switch is on, the BPS trouble relay is
dedicated to AC power loss reporting. The trouble relay switches within
20 seconds when AC fails or restores. The sense circuits immediately signal a
fault condition for any non-AC power loss faults. When AC power fails, the sense
circuits signal a fault condition after three hours of power loss.
