This power supply series is designed for installation with compliant fire alarm systems which require additional power for auxiliary devices connected to the system. The power supplies provide a voltage of 27.6VDC with options of 1A, 2A & 5A outputs and two different size enclosures depending on the battery size requirement.

In case of mains power failure, the PSU will switch to battery power, providing an uninterruptible power supply. The units are housed in a metal enclosure with space for two batteries. Maintenance free lead acid batteries are required to provide back up in the event of mains power loss.
