Control Panel Installation
4.1 Mounting the Control Panel Cabinet
Read the environmental specifications in Section 3.2 before mounting the MS-25 panel.
The MS-25 cabinet dimensions are:
12-3/4” W x 15-1/8” H x 3-3/8” D (32.39 cm W x 38.42 cm H x 8.57 cm D).
The MS-25 panel should be located within a secured area, where it is accessible to main drop
wiring runs and where it can be easily tested and serviced. Building occupants are responsible
for maintaining the panel should be able to hear alarms and troubles. When selecting a
location, keep in mind that the panel itself is the main source of alarm and trouble
annunciation.
When mounting on interior walls, use appropriate screw anchors in plaster. 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 MS-25 to the plywood. Also mount any other desired
components to the plywood.
DO NOT flush-mount the MS-25 cabinet.
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 MS-25 Assembly from the Housing
If it should ever be necessary to remove the control panel assembly from the cabinet for
repair, do so by removing the screws that hold the control panel in to the cabinet. Do not
attempt to disassemble the circuit boards.
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.
