29. DECT & FIXED CLI TELEPHONES
When the Advent xt is operating in Onsite Mode all alarm calls are reported via DECT cordless or desk CLI telephones.
When answered, a voice message will announce the call type and channel ID before a speech link is opened. With the fixed
CLI telephone and DECT models the caller will be identified on the LCD (provided the phone book memory is programmed).
A maximum of 4 telephone devices can be connected to the Advent xt controller via master BT sockets. The number of
telephones can be increased using a Matrix IP PBX & DECT telephone system.

DECT OVERVIEW

The maximum theoretical range for any DECT system is 500 metres under ideal conditions, in practice the range will rarely
exceed 300 metres due to reflections from nearby buildings, trees, water, etc. Obstructions inside buildings such as walls
and floors will reduce the range further, especially thick brick walls and reinforced concrete. It is impossible to state a
specific indoor range in advance of a site survey; however, as a guide you can usually achieve 50 metres.
Locating the wireless server/base station as high and free from immediate obstruction as possible will help to maximise its
range. Even if the wireless server/base station is placed in the optimum position it may not always achieve coverage in the
most remote corners, if this is the case then additional repeaters will be required.
Repeaters are generally placed in a star configuration around the wireless server/base station; however, it is possible to
extend the coverage in one direction with up to 3 repeater jumps. A site survey will always be required to establish the
best DECT system and base/repeater configuration required.
The wireless server, base stations and repeaters should always be located at least 5 metres away from the Advent xt
controller or network receivers and any other electrical equipment to avoid the risk of interference.
There are 3 DECT options;
1. Kirk 400 Solo Base ‐ for small installations
2. Kirk 400 Multi Cell ‐ for most medium/large installations
3. Kirk 6500 ‐ for very large or complex installations
