Trouble and Supervisory conditions

When the module detects a disconnected battery lead, it creates a shorted condition on the supervising zone or point.
Program the panel according to the appropriate programming guide to generate a trouble response to a shorted
condition on the loop. Reset the module by reconnecting the battery lead and clearing the trouble condition at the
FACP.

Caution!

When two batteries are connected in parallel to a FACP with on‑board battery lead supervision,

the panel cannot detect a single missing battery. Use this module in all fire applications using two

parallel batteries.

Notice!

The module will also indicate a trouble condition if one or both of the batteries are connected

with their polarity reversed. To reset, disconnect the batteries and reconnect properly.
