INSTALLATION MANUAL
General
The Fyreye MkII Addressable Input/Output Module is supplied with a backbox for surface mounting.
NOTE: The Input/Output Module is designed for indoor use only.
This product is loop powered and a maximum of 60 devices are allowed on any Zeta detection loop.
Model No: ZAIO-MI
Fyreye MkII Addressable Input/Output Module With Isolator
Surface Mounting
1. Mount the backbox as required and install all cables for termination.
2. Set the address of the unit as shown on page 3.
3. Terminate all cables.
4. Gently push the completed assembly towards the back box until the mounting holes are aligned and secure with the two mounting screws provided.
DO NOT OVERTIGHTEN.
Isolator Module
The ZAIO-MI Module is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output.

Address Setting
The address of the Input/Output Module is set using the eight segments of the DIL switch. Each segment of the switch must be set to “0”(ON) or “1”(OFF), using a small screwdriver or similar tool. A complete list of address settings is shown overleaf. The maximum address is 250.
Alternative Soft Addressing Option
Using our hand held MkII programmer (Part No: 48-004), the unit can be addressed electronically.
Step 1: Set all addresses to zero 0000000
Step 2: Connect leads to LOOP IN+ and LOOP IN- as shown below
Step 3: Follow the procedure as described in the handheld programmer manual.
NOTE: When a device is soft addressed as above, the address CANNOT BE CHANGED by mechanical setting of the dip-switch. In order to re-enable the dip-switch the unit needs
to be set electronically back to zero first.
Isolator Function
The Isolator Function can be enabled or disabled according to the wiring method.
A. Enabling the Isolator Function
B. By-passing the Isolator Function

Troubleshooting
Before investigating individual units for faults, it is very important to check that the system wiring is fault free. Many fault conditions are the result of simple wiring errors. Check all connections to the unit and make sure that the correct value resistors are fitted where necessary.
Faultfinding
Problem | Possible Cause | ||||||||||||||||||||||||||||||||||||||
No response or missing | Incorrect address setting Incorrect loop wiring | ||||||||||||||||||||||||||||||||||||||
Fault condition reported | Incorrect input wiring | ||||||||||||||||||||||||||||||||||||||
Relay fails to operate | Control panel has incorrect cause and effect programming Incorrect address setting |
||||||||||||||||||||||||||||||||||||||
Relay energized continuously | Incorrect loop wiring Incorrect address setting |
||||||||||||||||||||||||||||||||||||||
Analogue value unstable | Dual address Loop data fault, data corruption |
||||||||||||||||||||||||||||||||||||||
Constant alarm | Incorrect wiring Incorrect end-of-line resistor fitted Incompatible control panel software |
