ページを印刷する3. Maintenance
Detectors connected via an Accessory Enclosure should be calibrated and maintained in accordance with
the instructions provided with them. As a minimum Crowcon recommends that detectors are tested every six
months and re-calibrated as necessary.
All alarm output functions from the control panel should be verified on a six-monthly basis, and connections
between the Accessory Enclosure and the detectors and control panel should be check to ensure they are
secure.
