though it may be modifi ed for use with other types of equipment, as well, provided they are equipped with Form C or
Normally Open (N.O.) failure contacts.
All status contact connectors are for alarm inputs only and each is labeled INPUT. Two 3 position terminal block
connectors are provided for the summary alarm output and the Pre-LVD alarm. The output of the PFM summary alarm
and Pre-LVD alarms is Form C.
