3. INSTALLATION
Overview
A typical installation comprises the following main steps:
1. Carry out a Risk Assessment of the premises and agree a security grade
for the proposed alarm installation. Decide on positions for wired
detectors, control unit, keypads, external and internal sounders. As part
of the site survey ask the user what facilities they require .
3. Ensure that there is a suitable mains supply present at the site of the
control unit.
4. If you are going to use a communication device (for example a Speech
Dialler) arrange for a PTT (Public Telephone and Telegraph) connection
point near to the control unit.
5. Install the wired detectors and run cables to the control unit. Connect
each detector to its cable.
7. Run cables from the keypads, external and internal sounders to the
control unit.
8. Install keypads and connect them to their cabling. Ensure that each one
has the correct address setting.
9. Install internal and external sounders and connect them to their cabling.
10. Install the control unit and connect it to the mains supply cabling. Do not
apply power at this point.
11. At the control unit, complete all connections to keypads, and sounders.
12. Apply power and program the control unit.
13. Test that the alarm system functions as required.
14. If required, install a communication device (for example a Speech
Dialler), connect it to the PTT network, and check that it functions
correctly.
15. Hand the system over to the user and instruct them in its use.
Cabling Keypads
Cooper Security recommend that you use a minimum 4-core 7/0.2 alarm
cable for wiring keypads.
You can connect the keypads in either a star or bus configuration. If you are
intending to use long cable runs then Cooper Security recommend that you
use star wiring with no more than 300m of cable total for the keypad wiring.
The maximum length of any one run from control unit to the most remote
keypad depends on the number of items connected to the cable. You can
double the maximum length by using two cores each for the 0V and 12V
terminals or by using 16/0.2 cable. The table below shows the maximum
