For ease of removal, Z620 series detectors plug into a range of base units. In order to prevent unauthorised removal, a site selectable option is provided to lock the detector into its base. Once applied the unit can only be removed by means of a special tool.
All Z620 detectors feature head out monitoring support. Should a detector be removed from its base, in addition to giving a fault signal, all devices down line of the removed unit continue to function normally when the detectors are used with a Z6-BS5-P diode base.
