The HCMD0004SS battery charger kit replaces the battery charger in a Metron FD4 diesel fire pump controller. It can be configured for either 12 or 24 volt DC battery systems, accepts a wide 100–305 volt AC input, and ships with an adapter plate and installation instructions.

Diesel fire pump controllers rely on the charger to keep the engine's cranking batteries ready at all times, so a charger fault alarm, low-voltage alarms, or batteries that will not hold charge between weekly tests are common reasons to swap the unit. The included adapter plate and instructions support retrofit installation in the existing FD4 enclosure.

This kit fits the Metron FD4 diesel fire pump controller and is sold as part number HCMD0004SS. Cybertronic Controls is veteran-owned and ships from Hammond, Louisiana — call 985-351-5681 to verify compatibility with your controller before ordering.
