Typical Wiring Diagram
Note:
Polarity must be observed on detector as indicated on schematic wiring diagram.
Earth terminal is provided to maintain earth screen continuity. It does not connect to this detector head.
Base Installation
Connect the zone wires to the appropriate terminal. Tighten with a correct sized screwdriver: a wrong screwdriver may damage the screw
heads.
Make sure that the base contacts are clean and unobstructed.
Note, the base model No. for MKII-A Series is MKII-CB or MKII-CB/D.
Detector Head Installation
If there is still minor construction work in progress, the head may be fitted, provided that the dust cover is still in place.
To fit the detector, mate the detector onto the base and rotate the detector in clockwise until the detector loads into the base.
Continue to twist clockwise to secure it.
