Special Handling
Circuit cards are to be stored in anti-static packaging and kept away from the sun and from direct sources of intense
UV light. The circuit card may be subject to degradation due to electrostatic discharge; therefore grounding straps
must be worn when handling the cards.
Cable Entry and Internal Routing
On the enclosure there are two removable cable entry plates. These plates are to be removed, punched, and re-
installed. If additional entry holes are required outside the cable entry plates, before punching cable entry holes,
disconnect the door ground strap and remove the enclosure door with attached electronics.
Cable entry holes must be punched in accordance with the following criteria:
• Separate holes are required for the entry of Power-Limited and Non-Power-Limited circuit cables.
• Centre-to-centre spacing between an entry hole for Power-Limited circuit cables and an entry hole for Non-
Power-Limited circuit cables must not be less than two (2) times the diameter of the larger entry hole.
• Sufficient clearance must be provided around each hole to allow for any required conduit fittings, cable-clamps,
lock nuts, washers or other hardware.
• At no point inside the enclosure must the spacing between power-limited and non-power-limited circuit
conductors be less than 6,4mm (¼ po).
Wire lengths inside the enclosure should be kept to a minimum.
Cables must not interfere with, or touch any circuit card components other than the intended connector terminals.
Grounding and Bonding
All supply and device wiring must be grounded and bonded in accordance with applicable local regulations
governing the wiring of Fire Alarm Systems. The enclosure must be connected to earth Ground.
Enclosure Installation
All cable entry holes should be punched out prior to installation of base.
Ensure wall or structure to which the enclosure base is being mounted is capable of supporting a fully loaded unit.
Sufficient clearance must be provided around the unit to allow the enclosure cover door to be fully opened (180°)
without impediment. The enclosure box may be semi-flush mounted provided no less than 5 cm (2 inches) of the
box frame protrudes from the wall surface.
The top of the enclosure should be no more than 2 meters (6.7 feet) above the finished floor.
Recommended mounting hardware: four ¼ “ pan head screws (if bolts are used, four suitable flat washers are
required).
1. Remove the ground strap (14 Gauge, green) between the enclosure base and door by loosening and removing the
ground stud nut and star washer.
2. Remove the enclosure door from the slip hinges.
3. Secure the enclosure to wall using the four ¼” pan head screws.
4. Reinstall the door and ground strap between the door and the enclosure base.
