Replacing an ESM-01 Plug-in Sensor
1. Turn off or disconnect power to the M2A.
2. Unscrew the detector cap from the detector housing body. Take care not to lose the cap gasket.
If the splashguard begins to unscrew from the detector cap, make sure to remove the detector
cap also. See Figure 8 for an illustration of the ESM-01 detector.
3. Unplug and remove the sensor.
4. Carefully match the replacement sensor’s plug with the socket in the housing body and plug it
in.
WARNING: The ESM-01 detectors cannot be changed from one type to another. Replace the
plug-in sensor only with the same type of ESM-01 sensor.
5. Make sure the cap gasket is in place and screw the detector cap back onto the housing body. If
the splash guard was unscrewed from the detector cap, screw it back onto the detector cap.
6. Turn on or reconnect power to the M2A.
NOTE: Allow the replacement sensor to warm up for 15 minutes before you continue with the
