Power Supply Maintenance

The VESDA system power supply should be checked, at least, every six months or as required by local
codes and standards. VESDA products are designed to operate between 18 VDC and 30 VDC. We
recommend, as an absolute minimum, that you check the following:

l

Input voltage - from DC power supply to detector.

l

Output voltage - from detector to other devices.

l

Backup battery voltage - 24 VDC.

l

Charging backup battery voltage - typically 27.6 VDC.
