The FRM-1A ULC Listed Addressable Relay Module provides the system with a dry-contact output for activating a variety of auxiliary devices, such as fans, dampers, control equipment, etc. Addressability allows the dry contact to be activated, either manually or through panel programming, on a select basis.
Features
• Built-in type identification automatically identifies these devices to the control panel.
• Internal circuitry and relay powered directly by two-wire SLC loop.
• Integral LED “blinks” green each time a communication is received from the control panel and turns on in steady red when activated.
• LED blink may be deselected globally (affects all devices).
• High noise immunity (EMF/RFI).
• Wide viewing angle of LED.
• SEMS screws with clamping plates for wiring ease.
• Direct-dial entry of address 01– 159 for FlashScan loops, 01 – 99 for CLIP mode loops.
Applications
The FRM-1A may be programmed to operate dry contacts for applications such as door holders or Air Handling Unit shutdown, and to reset four-wire smoke detector power.
Construction
• The face plate is made of off-white heat-resistant plastic.
• Controls include two rotary switches for direct-dial entry of address (01-159).
• The FRM-1A provides two Form-C dry contacts that
switch together.
Operation
Each FRM-1A uses one of 159 possible module addresses on a SLC loop (99 on CLIP loops). It responds to regular polls from the control panel and reports its type and status, including the open/normal/short status of its Notification Appliance Circuit (NAC). The LED blinks with each poll received. On command, it activates its internal relay.
Rotary switches set a unique address for each module. The address may be set before or after mounting. The built-in TYPE CODE (not settable) will identify the module to the control panel, so as to differentiate between a module and a sensor address.
