Technical Specifications

The Honeywell FC-BKM-0001 delivers uninterrupted operation during main power loss. Its integrated key switch allows manual mode selection. Therefore, this module suits safety-critical and battery-backed applications.

Temperature Ranges & Environmental Tolerance
The Honeywell FC-BKM-0001 operates from -5°C to +70°C. Similarly, its storage temperature ranges from -40°C to +85°C. Relative humidity tolerance spans 10% to 95% non-condensing. Consequently, this wide envelope ensures reliable performance in harsh industrial facilities.

Power Supply Requirements
This module needs a 24 Vdc supply with -15% to +30% tolerance. For instance, the FC-BKM-0001 draws a maximum 20 mA from each 24 Vdc input. In contrast, typical current draws only 7 mA under shared load. It also requires a 5 Vdc supply at ±10% tolerance. Furthermore, this draws a maximum 10 mA only.

Output Specifications & Protection
The Honeywell FC-BKM-0001 provides output supply voltage from 14 to 31 Vdc. Meanwhile, output resistance measures approximately 2 × 1.1 kΩ in parallel configuration. The module features continuous short circuit proof protection. As a result, this prevents damage from wiring faults or accidental shorts.

Input Signal Characteristics
For input signals, voltage high ranges from 14 to 35 Vdc. However, voltage low sits below 7 Vdc with reverse polarity protection. Input current measures 2.3 mA at 24 Vdc. Specifically, the FC-BKM-0001 includes three inputs with different filters. Input 1 filter is typically 0.1 ms. In addition, Inputs 2 and 3 filters are typically 10 ms.

Battery Specifications
The Honeywell FC-BKM-0001 uses a SAFT brand battery. Specifically, the recommended battery type is LS14500CGFG. Alternatively, you can use battery type LS14500W. The material consists of Lithium Thionyl Chloride. Therefore, nominal voltage reaches 3.6 V. Capacity exceeds 2 Ah, and battery size is AA. Finally, the operating temperature for the battery spans -40°C to +85°C.

Physical Dimensions & Weight
This module measures 176 mm in height, 35.2 mm in width, and 212 mm in depth. Total weight reaches 0.5 kg (500 g). Therefore, the FC-BKM-0001 fits compact Honeywell rack systems easily.

Certifications & Approvals
The Honeywell FC-BKM-0001 holds multiple global approvals. For example, these include CE, TUV, UL, CSA, and FM. Consequently, these certifications guarantee compliance with international safety standards.

Installation Guide

Follow these steps to install the Honeywell FC-BKM-0001 correctly. First, power down the system and turn off all power to the chassis. Then, insert a fresh SAFT LS14500CGFG battery into the holder. Next, align the FC-BKM-0001 straight into the guide rails. After that, press firmly until the locking mechanism engages. Meanwhile, tighten the top and bottom retaining screws. Then, connect both the 24 Vdc and 5 Vdc power sources. Finally, wire the key switch contacts to your control input. Once complete, restore power and verify the battery status LED.

Frequently Asked Questions (FAQ)

Q1: How long does the battery last on the FC-BKM-0001?
The Honeywell FC-BKM-0001 battery exceeds 2 Ah capacity. However, battery life depends on load current. Therefore, typical service life reaches 3 to 5 years under normal conditions.

Q2: Can I use a different battery brand instead?
No, Honeywell recommends the FC-BKM-0001 with SAFT LS14500CGFG only. Alternatively, you can use LS14500W. Other brands may not meet the temperature range or capacity specs.

Q3: What happens when the battery voltage drops too low?
The Honeywell FC-BKM-0001 monitors battery voltage continuously. Consequently, a low battery warning appears on the status indicator. For this reason, replace the battery immediately after any warning.

Q4: Is the key switch removable or replaceable in the field?
Yes, the key switch on FC-BKM-0001 is a field replaceable component. Therefore, contact Honeywell for the exact replacement part number. However, do not use third party key switches.

Q5: Does this module require both 24V and 5V supplies to operate?
Yes, the Honeywell FC-BKM-0001 needs both power sources. Specifically, the 5V powers the monitoring circuits. Meanwhile, the 24V powers the output and battery charging circuit.
