The Simplex 4098-9847 extension box mounts a TrueAlarm Sensor Guard onto a surface electrical box.
Specifically, it pairs with the 4098-9846 Sensor Guard. First, you fasten the guard frame to this extension box. Then the assembly shields the sensor in abuse-prone areas. As a result, detectors survive rough settings like jails, dorms, and industrial spaces.
Simplex 4098-9847 extension box installation
Simplex supplies the bolts that secure the guard frame to the box. However, you should use this box only with surface-mounted electrical boxes. In addition, it should not mount over flush boxes. Otherwise, it will not position the sensor correctly.
Therefore, the 4098-9847 is the correct surface-mount accessory for the 4098-9846 Sensor Guard.
