The RJ12 connector offers two possibilities for wiring, either a switch to GND or a 12V output. If the 

12V output is used, the power for the relay coil is supplied by the Kanomax AC/DC adaptor. In this 

case, ensure that the relay coil does not draw more than 150mA and that a protection diode is 

inserted across the relay coil.

 

 

If the switch to GND output is used, ensure that the relay coil does not draw more than 150mA, that 

the voltage does not exceed 24V and that a protection diode is inserted across the relay coil. 

 

5.1.  Wiring for Alarm

 

The high alarm and low alarm pins can be wired to supply simple on / off switching to operate 

equipment which requires only an on or off signal, such as an alarm.

 

To switch to GND use pins 4, 5 and 6. For a 12V output wire to pins 4, 5 and 1 (see the following 

diagram for typical wiring for high alarm). This feature will only operate while powered by the AC 

adaptor. 

 

 

High gas level alarm 

 

 

 

 

 

 

 

Note: Failure to insert a circuit protection diode, shown as above, will result in damage to the 

monitor if a voltage spike is created by the relay.

 

 

5.2.  Wiring for Control

 

The control pin can be wired to supply control of a gas concentration between upper and lower 

concentration limits. The upper and lower limits can be set by the user. The factory default settings 

are dependent on the gas sensor head selected at time of purchase.

 

To switch to GND use pins 3 and 6. For a 12V output wire to pins 3 and 1 (see following diagram for 

typical wiring). This feature will only operate while powered by the AC adaptor.

 

Control is achieved by using a software latch. If power is lost to the monitor, the switch will open and 

therefore turn off the external device connected to the monitor external output. The following wiring 

diagram demonstrates the typical wiring to achieve the required control.
