The Supervisory and Security contacts can also be configured as Alarm contacts by setting
switches SW1 and SW5 away from the factory default positions shown in Figure 18. Follow
sequence of steps in Section 3.2 “Installation Checklist”, Table 2; this is part of Step 6.

3.5.14 Backup-Alarm Switches
Backup alarm switches are provided that enable NACs
and the alarm relay to activate during a backup alarm
condition. If the main board’s microcontroller fails and
an alarm is reported by any detector or a monitor
module that has backup reporting enabled, the NAC
will turn on if the corresponding switch was enabled.
The alarm will activate during microcontroller failure
regardless of the settings of Switch 6-9.
• Switch 6 - NAC#1
• Switch 7 - NAC#2
• Switch 8 - NAC#3
• Switch 9 - NAC#4
So, for example, if Switch 6 and Switch 8 were enabled at the time of an alarm during
microcontroller failure, NAC#1 and NAC#3 would activate. Follow sequence of steps in Section
3.2 “Installation Checklist”, Table 2; this is Step 7.
3.5.15 Installing a Transmitter Module TM-4
TM-4 is power-limited. Connections are on TB7 nonresettable output and TB13 EIA-485 ACS
Mode. Refer to the Transmitter Module TM-4 installation document for installation details.
