Sense circuit wiring
The BPS has two Class B sense (activation) circuits (Sense 1 and Sense 2). See
Figure 13 and Figure 14.
Note:
When NACs 1, 2, 3, and 4 are configured for AUX (Figure 16), sense
activation of NAC circuits reports a trouble condition to the control panel using
these circuits.
Any BPS trouble opens the sense circuit, which sends a trouble event message
to the control panel, indicating that a trouble exists on that circuit.
AUX power wiring

NAC configured as AUX power
Each NAC can be configured through a DIP switch for use as AUX power. A DIP
switch also controls AUX operation during AC power loss. See “Setting the DIP
switches” for details.
This auxiliary configuration is compatible with fire alarm, security, and access
control applications, which can be combined in a single system, if all of the
devices are listed.
Trouble relay wiring with four AUX circuits
When all four NAC/AUX circuits are configured as AUX circuits and DIP switch
SW2-6 is ON, a SIGA-CT2 module must be used to monitor the sense 1 trouble
contacts and the trouble relay.
