The IDP-MONITOR-2 is an addressable monitor module with two initiating circuits for use with Honeywell Farenhyt Series fire alarm control panels (FACPs). The IDP-MONITOR-2 acts as an interface to contact devices, such as waterflow switches and pull stations. The IDP-MONITOR-2 supports Class B supervised wiring to the load device. Conventional 4-wire smoke detectors can be monitored for alarm and trouble conditions. Because the IDP-MONITOR-2 is capable of monitoring two separate Class B circuits, it is ideal for waterflow tamper switch and flow switch monitoring.
