6. The CXT Sensor can also be wall-mounted using the four holes provided in the mounting brackets.
The method of securing the device to the wall is via all four mounting holes, which shall safely
support four times the weight of the unit. The unit’s weight is 17 lbs = 7.7 Kg and the safe weight
support requirement is 68 lbs = 31 Kg.
7. The correct wall installation will be attachment to a solid plywood structure of minimum 0.5”
thick. The recommended mounting bolt specification is a 3/8”-16 x 1-1/2” long 316SS hex head
bolt. The recommended nut and washer components are a 3/8”-16 316SS hex nut and 3/8”-16
316SS flat washer. The unit should be marked and measured for wall mounting at approximately
four feet height. The unit shall be held up to wall to mark off the location of the four outer spread
mounting holes located on the two mounting ears of the enclosure. Four clearance holes of 0.5”
OD should be drilled through the wood. The unit is then held up in place and the bolts are passed
through the enclosure mounting ear holes and the wood. On the back side of the wood, an assistant
should secure the washers and hex nuts to hand tight torque.
CAUTION
The method of securing the device to the wall is via all four mounting holes, which
shall safely support four times the weight of the unit. The unit weight is 17 lbs =
7.7 Kg and the safe weight support requirement is 68 lbs = 31 Kg. This is required
to avoid the unit from unexpectedly falling off and causing a safety hazard.
NOTE
Position the wall mounted CXT controller such that all disconnecting devices are readily
accessible.
8. If the unit is ordered with the optional external A1 C1D2 Horn, the horn should be mounted either
on the tripod, or on a separate tripod. The optional A1 C1D2 Horn requires the cable for the
External ‘Wet’ Alarms.
a. The horn should be wired to the ‘Wet’ Alarm Output cable per Figure 12.
b. The alarm Cable should be connected to the External Alarm Connector on the controller.
