TYCO 4B-C Base (Lot 4) New - Factory Sealed Fire Detection Modules

Product Overview

The Tyco 4B-C is a high-quality Continuity Base designed for use with Tyco’s range of addressable fire detectors. This base is a critical component for fire safety installations, as it features a continuity spring that allows the detection loop to remain closed even when the detector head is removed. This ensures that the rest of the loop remains operational during maintenance or head replacement. This listing is for a Lot of 4 (Four) units, all in New - Factory Sealed condition, providing a reliable and compliant solution for professional fire alarm system installers.

Key Features

• Loop Continuity: Integrated continuity spring maintains circuit integrity when the sensor is removed, preventing "Open Circuit" faults on the panel.
• Universal 4-Inch Design: Standard footprint that accommodates various Tyco and FireClass addressable smoke and heat detectors.
• Simplified Wiring: Features robust, clearly marked terminals for Loop In, Loop Out, and Remote Indicator connections.
• Aesthetic Integration: Low-profile, white plastic finish designed to blend seamlessly into commercial and industrial ceilings.
• Secure Fit: Precision-engineered twist-lock mechanism ensures a firm electrical and mechanical connection with the detector head.
