Sensazone is an intelligent PIR sensor which controls the water flow to the washroom with solenoid valves. When sensazone detects a user entering the washroom it activates the solenoid valves to allow water to flow into the washroom. If no motion has been detected for a user configurable time of either 15 or 30 minutes, the valve will close the water supply to the area until further movement is detected.
If a washroom outlet is defective or tampered with, water from the mains or central supply can pass uncontrolled through the outlet valves such as taps or WCs. This waste of water can often pass undetected and cause considerable costs. As the sensazone controls the flow of water into the washroom area at the entry point, the water is prevented from passing uncontrolled through the damaged outlet, which eliminates the risk of water wastage or flooding during vacant periods.
The washroom control has been designed as a simple yet effective management system for controlling all primary services within the washroom. Occupancy is constantly monitored by up to 10 PIR sensors strategically placed throughout the washroom. This ensures that the washroom services remain active when facilities are required and remain inactive when they are not.
When someone enters the washroom all services controlled by the washroom control unit are activated; the hot and cold water solenoids open, lighting is switched on (if necessary), the extractor-fans start turning and the internal timers begin counting. Every service system in the washroom is set to run for a fixed time or ‘service cycle’ which is determined by the installer. The PIR sensor(s) will remain active while the washroom is occupied and send signals to the power and solenoids to remain on and open respectively.
When the washroom is vacated the PIR sensor signals are no longer sent, the timers are not re-started and the washroom control sends no further output signals so the washroom services complete their service cycles and shut down.
This automatic shut-down process eliminates the costs of unnecessary lighting and hot and cold water loss caused by open taps and leaking valves. It also significantly reduces the risk of damage and associated costs from floods or vandalism, whether deliberate or accidental.
