Type of Sensors

WATER

Water damage from a leak or burst pipe
can be very expensive and inconvenient.

REFRIGERANT GASES

All refrigerant gases including: Ammonia, Carbon
Dioxide, Hydrocarbons, Halocarbons – HFCs, HCFCs, CFCs.

COMBUSTIBLE GASES

Such as: Methane, LPG, Propane, Butane, and
Hydrogen

MISC INPUTS

Using the Digital Input on our system
You can use the following switches
which in turn can use a relay

Water Detection - Examples

24Vac Four Zone Water Leak Detection Module

The WLM4 Leak detection module has 4 inputs with zone indication and 1 common Output with fault indication. Din rail or wall mount options. The WLM can be used with a combination of sensors.

Gas Sensors - Examples

Bacharach HFC Sensor

– 1 or 2 alarm levels
– Refrigerant, combustible, toxic or
environmental gases
– Visual alert
– Audible alert
– Common relay per alarm level
– Flexible housing & remote sensor
head options

GS-CO2-1001

The GS-CO2 is a non-dispersive infrared sensor for measuring CO2 concentrations in controlled spaces.

Misc Inputs

Water Leak Cable

The water leak sensor cable is a multi-conductor wire with embedded gold plated sensors every 3 feet. These water detection sensors act as extensions of the sensing probes contained within the detector. Should any of the sensors come in contact with liquid moisture the Water Alert will activate.
