Gas detectors for car parks
IP55 Protection Degree
11...28Vdc power supply..
Pellistor sensing element for flammable gases, and Electrochemical Cell for toxic
gases.
Up to three alarm threshold.
Automatic counting life time of sensors.
The UR.20SP sensors, being specifically designed for car parks, are used primarily to
detect the presence of Gasoline vapours and carbon monoxide (CO), but also
methane gas, LPG and, on demand, nitrogen monoxide (NO) and nitrogen dioxide
(NO ).

The UR.40.L detectors transmit data from a local bus connected with their Control
Unit, which acts as the master unit of the gas detection system.
If there is a gas leakage, the detector compares the measured concentration value
with the threshold limit setpoints.
Alarm information is transmitted to the Control Unit, which energises its own internal
relay module (MR0) and the remote Relay and Display modules depending on the
associations.
To order, simply state the part number: see "available models".
