FW811 Input Module
The FW811 input module monitors a single dry contact, and is a UL/ULC listed device according to UL864 and ULCS527 for fire protective signaling systems for indoor use.
The field circuit is monitored for open line faults and ground faults and the contact must be wired with an end of line resistor. The type of input contact is configurable for NO/NC operation.Read More
FW821 I/O Module
The input-output module FW821 is a UL / ULC listed device according to UL864 and ULC-S527 for fire protective signaling systems for indoor use. FW821 provides one 24VDC output and in addition monitoring for one feedback input contact.
The input line is monitored for open line faults and ground faults and the contact must be wired with an end of line resistor. The output line is monitored for open line, short circuit faults, ground faults, external 24VDC power source loss and an end of line resistor is needed as well.Read More
FW831 Relay Module
The relay module FW831 is a UL / ULC listed product according to UL864 and ULC-S527 for fire protective signaling systems for indoor use.
FW831 provides two control relay outputs which will be activated simultaneously. When the outputs are activated, the device LED will indicate the event condition by fast blinking. Supports both normally closed and normally open output contact configurations.Read More
FW851 Isolation Module
The FW851 isolator module isolates the short point on the signaling line circuit (SLC). The internal relay will be triggered to cut down the line power where the short trouble is detected.
The device LED will indicate the trouble condition by yellow steady on. A return to normal condition will cause the internal relay to normal position to restore the line power and the device LED indicator will return to the idle condition.Read More
FW951 Sync Module
The FW951 Sync Module is a device designed with FW961/FW971/FW981 Horn and/or Strobe with a built-in synchronization circuit to synchronize multiple FW961s in a complete fire alarm system.
There are up-to 64 Notification Appliance Circuits (NAC), networked, stand alone or interfacing with the FW951.Read More
