3. INSTALLATION
Caution: Always remove mains power before opening the case lid. Do
not work inside the control unit with mains power present.
Overview
A typical installation comprises the following main steps:
1.
Survey the site and decide on positions for wired detectors, 9954 wired
expanders, control unit, keypads, external and internal sounders. As part
of the survey ask the users what facilities they need.
2.
If you are going to use wirefree detectors, carry out a radio site survey
and decide on positions for the wirefree detectors and the radio
expanders. For more information, refer to the "Installation and
Programming Guide" for the expander you are using.
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 communicator, 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 site of the control unit or
9954 wired expanders. Connect each detector to its cable.
6.
Run cables from the sites of the keypads, expanders, and external and
internal sounders to the site of the control unit.
7.
Install keypads and expanders, and connect them to their cabling.
Ensure that each one has the correct address setting. If necessary,
install 934 ScanProx modules on the keypads.
8.
Install internal and external sounders and connect them to their cabling.
9.
Install the control unit and connect it to the mains supply cabling. Do not
apply power at this point.
10. At the control unit, complete all connections to keypads, expanders and
sounders.
11. Apply power and program the control unit.
12. Let the radio expanders learn the wirefree detectors and then install the
detectors at their selected sites.
13. Test that the intruder alarm system operates as required.
14. If required, install a communicator, connect it to the PTT network and
check that it operates correctly.
15. Hand the system over to the users and instruct them in its use.
