UPS / Battery Backup

UPS (Uninterruptible power supply) or battery backup.

This device is designed and supplied mainly in conjunction with our single phase 230v fire shutters to allow the door to close (or open) on receipt of a fire signal, it’s also used when a 230v shutter is a final exit from a building and if a use of a manual override device would compromise security.

Correct sizing of the unit is essential for the expected motor load and with consideration of the fact that all battery units will lose capacity over time so it’s always wise to include spare capacity in your calculations when installing these units.
