4.13.4 Using the SD500-ARM Addressable Relay Module
When the SD500-ARM is wired for polarity reversal, it reports alarm and trouble events to a remote site. Alarms
will override trouble conditions and it will not be possible to reset the remote indicator until the condition is
cleared and the control panel is reset.
Relay 2 must be programmed for Alarm (default).
Note: If you need to transmit supervisories or trouble conditions, additional SD500-ARM modules must be added.
Use relay 1 to transmit supervisory conditions. Use the trouble relay to transmit trouble conditions.
Wire the SD500-ARM as shown in Figure 4-35.
