Figure 2-1. Typical Detector/Sensor Mounting
Notes:
1. Break off plastic lock tab to engage locking mechanism. To lock detector/sensor into base,
turn unit until the locking tab clicks into place. To unlock detector/sensor, insert the blade of a
screwdriver into this slot and then pull down on handle. This action allows the detector/sensor
to be turned and removed (see Figure 2-1).
2. Refer to the “Compatibility and Testing” chapter of this publication for detailed information
on compatible detectors/sensors.
3. Bases with relay modules require a 1 ½-inch extension ring (not supplied) mounted to the
4-inch square or octagonal electrical box to meet the space requirement of the relay cube and
its wires. The relay module(s) cannot be used in single-gang electrical box installations. The
relay cube 4098-9822 must be installed in the electrical box directly behind the sensor base.
4. Use Adapter Plate Kit 4098-9832 when mounting the 4098-9794 and 4098-9795 to a surface
mounted 4-inch square or octagonal box. Adapter plates must be installed with textured side
towards the electrical box for this installation only.
