SE 127K

Central units to be connected to a remote sensor type SE 192KM or SE 192KG for methane and LPG, respectively.

Equipped with two alarm levels corresponding to two different concentrations of gas; they change over both relays as soon as the relevant alarm thresholds are reached. In most cases, the relays are connected to the devices as shown in the picture 2 hereafter. The concentration of gas monitored in the environment is displayed by the LED bar placed at the front of the device.

 

The central unit setting is intentionally delayed electronically by 30 seconds, in order to avoid any blind alarms due to the accidental presence of gases. The only difference of these central units is their installation system and rating. A TEST key to test the proper working condition of the unit and RESET the system at the end of an alarm condition completes the set of functions of these central units. In fact, the second-threshold relay (general alarm) remains stored as long as this key is not pressed.

Warning! A TEST key does not check calibration of sensors but a proper electric connection of the system.
