Edwards 6251C-003 Detector Base With Auxilary Relay

The Edwards 6251C-003 is an intelligent detector base with an integrated auxiliary relay designed for use with compatible Edwards Signature Series smoke and heat detectors. The Edwards 6251C-003 combines detector mounting functionality with relay control capability, allowing fire alarm systems to activate external devices directly from the detector location. Therefore, it provides a flexible and efficient solution for HVAC shutdown, door release, fan control, and other life safety control applications.

Edwards 6251C-003 Function

The 6251C-003 serves as both a mounting base and a control interface for compatible Edwards Signature Series detectors. As a result, the detector can initiate relay-controlled actions when programmed by the fire alarm control panel. In addition, the auxiliary relay allows external equipment to be activated or deactivated in response to fire alarm events, supervisory conditions, or custom system programming.

Integrated Auxiliary Relay

The Edwards 6251C-003 incorporates an onboard auxiliary relay that provides local control functionality directly at the detector location. Consequently, system designers can eliminate additional control modules in certain applications, reducing installation costs and wiring complexity. Furthermore, local relay control improves flexibility when interfacing with building systems.

Form C Relay Contacts

The auxiliary relay provides Form C (SPDT) contacts, allowing support for both normally open and normally closed control applications. Therefore, the base can be used for a wide variety of life safety and building automation functions. Additionally, the relay design offers dependable switching performance for critical control operations.

Intelligent Addressable System Integration

The Edwards 6251C-003 operates within Signature Series intelligent fire alarm networks. As a result, detector status, relay operation, and device supervision are continuously monitored by the fire alarm control panel. Moreover, intelligent communications improve troubleshooting, maintenance, and overall system reliability.

HVAC and Building Control Applications

The auxiliary relay function is commonly used for:

• HVAC shutdown
• Fan control
• Smoke control systems
• Magnetic door holder release
