Control Panel Installation
4.1 Mounting the Control Panel Cabinet
Read the environmental specifications in Section 3.2 before mounting the control
panel cabinet. This will ensure that you select a suitable location.
The panel should be accessible to main drop wiring runs. It should be mounted as
close to the center of the building as possible and located within a secured area, but
should be accessible for testing and service.
Mount the control panel cabinet so it is firmly secured to the wall surface. When
mounting on concrete, especially when moisture is expected, attach a piece of 3/4-
inch plywood to the concrete surface and then attach the cabinet to the plywood. Also
mount any other modules to the plywood.
The cabinet can be surface- or flush-mounted. If you flush-mount the cabinet, the
hole for the enclosure should be 14.75" W x 25" H x 4" D. Do NOT flush-mount in a
wall designated as a fire break.
4.1.1 Preventing Water Damage
Water damage to the fire system can be caused by moisture entering the cabinet
through the conduits. Conduits that are installed to enter the top of the cabinet are
most likely to cause water problems. Installers should take reasonable precautions to
prevent water from entering the cabinet. Water damage is not covered under
warranty.
4.1.2 Removing the 5820XL Assembly from the Housing
If it should ever be necessary to remove the control panel assembly from the cabinet
for repair, do so by unscrewing the nuts that connect the control panel assembly to
the cabinet. Do not attempt to disassemble the circuit boards. See Section 3.5 for
location of the nuts.
Caution!
To avoid the risk of electrical shock and damage to the unit, power should be OFF at the control
panel while installing or servicing.
