Product Overview

The “Nero” Water Detection System installed in vulnerable areas will continuously monitor the potential hazards- 24/7.
The system has the facility for 24 hour battery standby in the event of power failures.
The system has an attractive and unobtrusive control panel containing the alarm circuitry and power supply. Connection to the control panel via a simple two core leader cable of the recoverable moisture sensitive cable or point type localised detection probe provides rapid and cost effective installation. Upon detection of a leak, the green alarm lamp on the control panel willflash accompanied by a warning buzzer. The alarm may be extended to a remote location by extension sounder/indicator units. Disconnection of a moisture detection probe or break in the “Nero” moisture sensing cable is immediately indicated on the control panel by the yellow line fault indicator. This ensures that the integrity of the system cannot be compromised without a warning.

Floor Mounting Probe - PR2101

This adjustable height probe is simply screwed into the floor and adjusted to give the required detection level. An LED indicator on the top of the probe gives a clear indication of which probe has been activated and this may be extended to a remote lamp location (e.g. above false floor level) using a remote indicator. The probe is connected to the control panel wiring via a flexible cable which plugs into the probe. This plug connection is monitored by theline fault circuit of the control panel.

Drip Tray Mounting Probe -PR2102

This probe has exactly the same facilities as the floor mounting probe but has a bracket for mounting onto the side of an air conditioning unit drip tray. The probe is then adjusted to give the required detection level and plugged into the detection circuit.

“Nero” Moisture Sensing Cable

Available as either standard 5 metres,10 metres or custom designed lengths, “Nero” is a flexible cable which will continuously monitor large areas. When even a small amount of water comes into contact with the sensing cable it is absorbed by capillary action thereby triggering an alarm.
After the source of the leak has been removed, “Nero” will dry out in around 20 minutes for use again.
Unplugging or cutting the “Nero” cable will be immediately Indicated on the control panel by the line fault indicator.
Longer runs can be made by simply plugging lengths of “Nero” together. Special lengths can be made to order.
Each zone requires a junction box and an end of line DIN plug.
