CHAPTER 2
INSTALLATION AND COMMISSIONING
2.1 GENERAL
The installation of the fire detection and alarm system should comply with the current editions
of:-
1. The IEE Wiring Regulations.
2. The British Standard for Fire Detection and Alarm Systems for Buildings.
Care should be taken not to install cables in the proximity of high voltage cables or in areas likely
to induce electrical interference.
Junction boxes should be avoided but if they have to be installed then they must clearly be
labelled "Fire Alarm".
2.1.1 Static Sensitive Devices
A static sensitive device is any transistor or integrated circuit which may be permanently
damaged due to electrostatic potentials and is generally encountered during routine handling,
repair and transportation.
Static electricity is produced almost every time plastics or textiles are stroked or separated.
Static charges are collected on adjacent conductors and are delivered in the form of sparks
passing between conductors through insulating space or material. The sweat layer on the human
skin is a sufficient medium to store induced static charges and deliver then to any receptive
conductor such as a component or printed circuit board.
Static discharges can be reduced by adhering to the following guide lines:
1. Always use conductive or anti-static containers for transportation of storage.
2. Wear an earth wrist strap while handling, ensuring a good earth connection is maintained.
3. Never subject a static sensitive device to a sliding movement over any surface and avoid
any direct contact with the pins.
4. Avoid placing sensitive devices on plastic or vinyl surfaces.
5. Minimize the handling of sensitive devices and pcb's.
