Gas leak detection system
for heating rooms
UCE13.5 - UR.13/A - EXT6.5
UCE13.5
Microprocessor electronic gas leak detection system for heating rooms. Central
unit UCE13.5 can control up to three remote sensors (also for different types of
gas), and the system can be expanded with the use of one or more EXT6.5. Each
expander can control up to six additional remote sensors. Dedicated output for
normally closed (delivery condition) or normally open 12V solenoid valve. 230VAC
power supply with optional battery charger card UZY-13CB for a 12V back-up
battery. Input for optional relay card to drive auxiliary devices as fans, lamps or
additional 230VAC solenoid valve. Remote sensors for the detection of methane,
LPG and carbon monoxide with tin dioxide semiconductor sensing element.
The UCE13.5 Central Unit, with one or more remote sensors, is used for optical and
acoustical signalling and for command a solenoid valve for shutting the gas flow in case
of dangerous concentrations of:
Methane (CH
)
4
LPG
Carbon monoxide (CO)
The UCE13.5 and expander EXT6.5 can control simultaneously different types of
remote sensors for a complete gas monitoring of a heating plant.

Page 3: Mounting Instruction
Current local regulation must be observed. The devices must be directly connected to the mains and kept it permanently supplied. Check that UR.13./A sensors are suitable for the type of gas being measured and verify that the valve is suitable for the system characteristics.
