Honeywell FC-BKM-0001 | Safety Manager Battery and Key Switch Module

Description

Core Product Summary

The Honeywell FC-BKM-0001 is a specialized Battery and Key Switch Module designed for integration within Honeywell Safety Manager control system architectures. It serves a dual functional role by housing backup lithium batteries to maintain critical system data during power losses and providing physical key switches for authorized system control, diagnostics management, and security tasks.

Operating within the controller chassis, the module interfaces with 24 VDC and 5 VDC system supplies to support real-time clock functions, diagnostic databases, and control processor integrity. It incorporates two SAFT lithium thionyl chloride backup batteries alongside dedicated Force Enable and Reset key switches. The unit features continuous short-circuit-protected output circuitry, an operating temperature range of -5°C to +70°C, and compact industrial dimensions suited for standard safety controller rack installations.

Key Technical Specifications

Detailed Product Overview

The Honeywell FC-BKM-0001 module functions as an essential supervisory and backup interface within industrial safety instrumented systems. Installed directly into the Safety Manager control chassis, it bridges physical operational controls with internal system maintenance requirements.

The onboard battery system utilizes two non-rechargeable lithium cells to sustain critical volatile records, diagnostic logs, FTE IP addresses, and real-time clock operations on control processor modules during unexpected primary power interruptions. Simultaneously, the physical key switches provide plant operators and maintenance engineers with secure, controlled access points. The Force Enable switch allows authorized execution of safety functions, while the Reset switch clears specific diagnostic databases, defaulting to an open position when released to prevent unintended states.

Integration of the module requires strict adherence to safety control guidelines, including ESD-safe handling procedures, correct battery polarity verification, and precise matching of supply voltage parameters to avoid loop or chassis communication errors.
