Compatible with all ERA Wireless Alarm Systems, this Water Flood sensor triggers the alarm/ alert system when it detects water/liquid. When water/liquid is detected by the two detector probes, a signal is sent to the Control Panel, in turn sending an alert notification to system users. Highly reliable and easy to set up and ideal for use in areas such as kitchens, bathrooms, basements, utility rooms and where heating or water cylinders are housed; or in properties where there is a risk of flood. Battery operated and with a low battery indicator, the Water Flood Sensor is an ideal accessory for an ERA Alarm System. The box contains the Transmitter Module, batteries, Water Probe, fixing pack and instruction guide.
