Self-diagnosis sensor fault.
Construction and operation in accordance with BSI 7348, EN 50054 & CEI-UNI/CIG 70028 standards.
Power supply 230 V~ or 12V-; DIN rail mounting.

APPLICATION

RFG 65. is designed for the detection of gas leaks in spaces such as:
- boiler plants
- laboratories
- workshops
- garages.

FUNCTIONS

Monitors, according to type of sensor connected, the concentration in air of:
- natural gas,
- LPG,
- CO.
Indicates when pre-alarm threshold has been exceeded by blinking of alarm LED.
In the event that alarm threshold has been exceeded, RFG 65., by means of its output relays, can control:
