- Page 3 1) System Overview The unit has been designed to interrogate individual outstations and report back to the main controller if water or a disconnected sensor is found. On powering up, the unit will display “SETTING UP PLEASE WAIT” until all remote outstations have been interrogated for their current status. Providing there are no alarms or faults on the system, the displays backlight will change to green and all zones will be shown as “NORMAL”.

- Page 10 17) Fitting Cable Clips If Cable Clips are required, to protect the small sensor wires and to stop false water detected alarms from occurring insulating tape should be first applied around the detection cable before the clip tongue is closed. Clips should be fitted approximately every 1 to 1.5 metres apart. When using clips make sure that the cable touches the floor between the clips, DO NOT tighten the cable so that the cable does not touch the floor.
- Page 11 PLEASE NOTE; We don’t recommend that this type of valve and will NOT be supplied by CMR electrical. However, if this type of valve MUST be fitted, ensure that the arrow on its body facing the direction of flow, if not, the valve will not stop the flow of water.

- Page 13 24) Fault Diagnoses “Active” LEDS are provided on all outstations and the main alarm unit. The lights are provided to help when fault finding. When all interconnecting cabling is correct, the alarm unit “Active” LED should look to ON and all the outstation “Active” LEDS should be flashing. If the alarm units LED is OFF, it indicates that the controller can communicate to any of the outstations.
