SENSOR
An ELD-H sensor will last between 25 and 30 hours of continuous use. A failed or failing sensor will be
indicated in one of the following ways:
1. Unstable or erratic operation of the unit and many false alarms, even in pure air.
2. A continuous "siren" sound.
SENSOR REPLACEMENT
In either case, replacement of the sensor is necessary:
1. Turn the power off.
2. Locate the replacement sensor in the battery compartment.
3. Unscrew (turn counter clockwise) the old sensor from the end of the probe.
4. Screw (turn clockwise) the new sensor into place.

any kind.
