CRF-300 Addressable Relay Module

CRF-300 addressable relay modules provide a dry-contact output for activating a variety of auxiliary devices, such as fans, door holders, dampers, control equipment, etc. Addressability allows the dry contact to be activated through panel programming, on a select basis. Each relay module uses one of the addresses on a SLC loop. 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.

• Built-in type identification automatically identifies these devices to the control panel
• Internal circuitry and relay powered directly by 2-wire SLC loop
• High noise immunity (EMF/RFI)
• Wide viewing angle of LED
• SEMS screws with clamping plates for wiring ease
• Face plate is made of off-white heat-resistant plastic
• Controls include two rotary switches for direct-dial entry of address setting
• Configured for a single Class B (Style Y) or Class A (Style Z) NACs
• Provides two Form-C dry contacts that switch together
