Zeta MKII-HR Installation Manual

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 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 a clockwise direction until the
detector loads into the base. Continue to twist clockwise to secure it.
Model
There are 5 models of Fyreye II Conventional Detector.
Part No Model No.
80-200 MKII-OP
80-202 MKII-HR
80-204 MKII-HF
80-206 MKII-OH
80-208 MKII-HF/CS90
Monitor state
In monitor state, the two red LEDs on the top cover will blink every 5 seconds.
See Fig-1.
Pre-alarm state
In pre-alarm state, LED pairs will blink a clockwise circle in every 5 seconds.
Fire alarm state
In fire alarm state, the two LEDs shown in Fig-1 will light. The other 3-pairs of LED will light for 0.5 seconds
rotating clockwise.
False alarms
In case of false alarm, the LED pairs will blink alternately. Check if the air around the detector is
clear. Fan the air around the smoke alarm if necessary, until the alarm turns off. If the false alarm
occurs frequently or continuously, arrange to have the unit serviced.
Sensitivity Read
Take the Sensitivity Test Wand making the receive diode against the light-emitting diode (see Fig-2).
And push the button of the Sensitivity Test Wand, the sensitivity will be displayed on LCD of Wand for a few
moments later.
Drift Compensation Limit
In the case of the smoke chamber reaching the end of it`s compensation limit, the detector will flash it`s LEDs
continuously to signal that the detector should be replaced. This can be confirmed with the Sensitivity Test Wand.
