Chapter 3: Installation guidelines
3.1 Mains power connection
Use the mains connector terminal for connecting the mains supply. You can use a fixed cable or a flexible mains
lead to an earthed mains outlet. If fixed wiring is used, insert a dedicated circuit breaker in the power distribution
network. In all cases, the mains connection must comply with local regulations.
IMPORTANT:
Disconnect the mains power before opening the cabinet. To do this:
•
Disconnect the AC mains plug from the AC mains wall socket
or
•
Disconnect the mains with the dedicated circuit breaker.
CAUTION:
This unit can be provided with a lead battery inside. Dispose of this battery according to chemical
waste regulations only.
3.2 Mounting
•
Ensure that the unit is mounted on a flat, solid, vertical surface so that the base will not flex or warp when the
mounting screws/bolts are tightened.
•
Leave a 50 mm clearance between equipment enclosures mounted side by side and 25 mm between the
enclosure and the walkway.
•
The battery mounting facility inside the housing is only useful for steady state use of the control panel.
Remove the battery for transport of the control panel.
•
Take care that wire terminals are isolated. Use tie wraps to prevent contact with any other wires or circuits in
case wires break.
3.3 Cabling
3.3.1 Shielded and unshielded cable
•
In a clean environment, use unshielded cable. This provides the maximum cable length.
•
In a harsh environment, use shielded cable. The maximum cable length is reduced as part of the signal will go
into the shield. The amount of length lost depends on the type and quality of the shielded cable.
3.3.2 Twisted and untwisted cable
•
You can use either twisted or untwisted cable for the bus. Since the bus only has 3 wires, twisted pair cable is
not necessary.
3.4 Wiring guidelines
The CSx75 control panel has been designed, assembled and tested to meet the requirements of current relevant
standards related to safety, emission and immunity with respect to environmental electrical and electromagnetic
interference. Only a qualified electrician or other suitable trained and qualified person should attempt to wire this
system to the mains or to the public telephone network.
1.
Ensure that there is a good earth for the alarm system. A good earth is essential for effective resistance to
electrical interference. Do not forget to provide a (network) earth for the telephone dialler.
2.
Maintain a good separation between low voltage and mains supply cables. Use separate points of cable entry
to the control panel cabinet.
•
If the entry cable holes are used to route wiring into the control panel, always use a proper pipe fitting system
by means of an appropriate conduit and junction box. For this purpose, use only materials of suitable
flammability class (HB or better).
•
Avoid cable ducts and cableways that contain mains power cables. This is particularly important when such
ducts contain cables supplying electric motors, fluorescent lights or 3-phase power. If this is not possible,
