PREVENT [d]s – carbon monoxide and methane gas safety system

General Details


Certified quality – the detector holds a Kitemark Certificate issued by British Standards Institution according to the BS EN 50194-1:2009 and BS EN 50291-1:2010 standards

Simple design – friendly shape, easy to integrate in any home design

Dual detection: methane and carbon monoxide – electrochemical sensor and semiconductor sensor inside, designed to sense low levels of carbon monoxide and/or methane gas.

Dedicated – provides an alarm signal well before the carbon monoxide concentration in the house could reach levels dangerous to your health

Double alarm – provides both a visual alarm (red light) and an audible alarm (buzzer)

Remote control – the detector supplies an output signal to activate an ancilliary device which could be a fan, a siren or a shut-off solenoid valve

Knows the difference – designed to avoid false alarms caused by contaminant factors in your home

Auto diagnostic – contains an auto-diagnostic system that constantly checks the detector’s operation. The yellow light continuously turned on indicates a possible malfunction of the detector

Test – features a button for testing in normal working conditions, allowing the user to periodically check the functioning of the detector

Solenoid Valve

Normally open or normally closed safety solenoid valves with manual reset. The closing/opening function is
electrically activated.
This type of device connected to one or more methane gas detectors and/or carbon monoxide
detectors, is suitable for performing locking operations on the gas line.

An incorporated fine mesh filter protects the valve seat and disc as well as downstream components
and prevents dirty contamination (except brass models). All components are designed to withstand
any mechanical, chemical and thermal condition occuring during typical service. Eective
impregnation and surface treatments have been used to improve mechanical sturdiness, sealing and
resistance to corrosion of the components.
Valves are 100% tested by computerized testing machineries and are fully warranted.
