The M500DM module is capable of monitoring two separate Class B circuits simultaneously, making it ideal for waterflow tamper switch and flow switch monitoring.

The System Sensor intelligent module products are designed to meet a wide range of applications.

M500R relay control modules contain two isolated sets of Form C contacts, which operate as a DPDT switch. The modules allow the control panel to switch these contacts on command. No supervision is provided for the notification appliance circuit.

System Sensor multiple input and output modules are designed to meet a range of applications in which numerous single modules are used.

The System Sensor M500M-4-20 analog input module demonstrates our commitment to offer solutions for all applications.

Backboxes are for use with fire alarm control panels (FACPs) and are used to mount up to two batteries and power supplies.

CB500 wiring barriers are used to separate power-limited and nonpower-limited wiring inside of junction boxes.

FP-WHITE faceplates are designed for use with Silent Knight® addressable modules. They better compliment the design aesthetics of a modern building and also match white System Sensor® L-Series AV devices.

The System Sensor M500X Fault Isolator modules enable part of the communications signaling line circuit to continue operating when a short circuit occurs. The Module is an automatic switch that opens when the line voltage drops below four volts.

ISO-6 six fault isolator modules provide six equivalent circuits that will allow a portion of the communications loop to continue operating when a short circuit occurs on that loop.

Ivory faceplates are sold in packs of ten. All faceplates are unmarked (without logos).
