GAS LEAK DETECTORS
The new range of gas leak detectors under the name of “Gas Sentinel” for methane and LPG, available for wall
and flush mounting, comes with a new design and more compact size as well as with performance characteristics,
in terms of reliability and sensitivity in measurement, in accordance with current European standards (EN50194).
The alarm and closing of the solenoid valve are activated by the first or second threshold
depending on the programming of gas leak detector, selectable by user.
• Provision for simultaneous monitoring, through serial communication link, up to 11 zones:
(1 main detector + 10 secondary detectors)
• Provision for connecting the network of gas leak detectors to a PC for monitoring or programming the detectors
using a special software kit.
• Malfunction: the gas leak detector is provided with circuit for self-diagnostics, which, in the event of
critical fault of the sensor or to one of the main components, trips giving a visual signal (yellow LED).
Conforms with EEC 89/336, EEC 73/23, EN 50194. Certification pending.
Description
GAS SENTINEL
Gas leak detector, for domestic applications, for wall mounting, controlled
electronically via microprocessor, with audible and visual alarm, to be connected
to one or more solenoid valves, either normally closed (EVNC, EVNCR,
EVNCROT) or normally open (EVNA, EVNAOT).
GSX
GAS SENTINEL
Characteristics like GSX but for flush mounting. Compatible with the more
frequent commercially available plates and electrical boxes to DIN standards.
