Planning An Installation - C-TEC QT606A Manual

PLANNING AN INSTALLATION

Although Quantec far exceeds the minimum requirements of all agencies, rules regarding
installation may vary depending on the area of the country. If there is any doubt, please
check with the relevant authorities/building management.
The Quantec Controller can be located anywhere on the network although it is usually
installed centrally to reduce wiring runs or in the manager/matron's office. When not being
used for programming, it operates in exactly the same way as a display.
Displays should be located strategically around the premises where they can be readily seen by
staff, in areas such as junctions in corridors, staff rooms, etc.
In nursing home/hospital type applications, Call Points should be sited next to each bed
(preferably above bedhead height to avoid damage to them when the bed is moved) and in
lounges, dining rooms and other communal areas. In other applications such as leisure centres,
prisons, etc, they should be installed as advised by the client.
Ceiling Pulls should be fitted in each bathroom and WC.
Slave Overdoor Lights (if required) are normally installed outside rooms.
If area indication or 'follow me' lights are required, Addressable Overdoor Lights should be
positioned at the ends of corridors, above fire doors, etc.
Monitoring Points should be fitted close to fire exits, drug cupboards or alongside any other
area/device which needs to be monitored.
Infrared Ceiling Receivers/Call Points should be positioned in all areas which require infrared
coverage. The number and type of devices used will vary depending on the application. Note
that master infrared ceiling receivers can generate standard and/or attack calls only whereas
infrared call points can generate standard, help required, emergency and/or attack calls. Slave
ceiling receivers will generate the same levels of call as the master device they are connected to.
When deciding on the position of Infrared Ceiling Receivers, take into account the 10 metres
line-of-sight transmitting range of infrared transmitters. Use slave receivers in large open
areas, long corridors or 'L' shaped rooms where one master is unable to provide sufficient
coverage. Where possible, position master receivers in central positions and look at the
relevant sight lines. If any area of the room is out of sight of the receiver or is over 7 metres
away from it, boost coverage with slave receivers. If in doubt, use slaves (up to three slaves
can be used per master).
As Infrared Call Points are designed to be wall-mounted, pay particular attention to their
height as furniture or ornaments added to the room at a later date could obstruct them. As
with master infrared ceiling receivers, up to three slave receivers can be connected to one
master infrared call point.
Note that different types of lighting and wallcovering can affect the range of infrared
transmissions and rooms with excessively dark walls may require more infrared receivers than
rooms with reflective walls. Avoid placing receivers in direct sunlight. (Remember, when
surveying rooms that the sun's position changes and a room that is in the shade in the
morning may not be in the shade in the afternoon). Watch out for corridors with lots of
windows, conservatories and rooms with skylights - you may have to increase the number of
receivers used to compensate for this. Also, avoid placing receivers too close to fluorescent
lights and spot lights and be careful not to position them too close to smoke detectors,
lampshades or PA speakers as these may obstruct any signals transmitted.
Radio Receivers should be mounted internally - typically in a building's roofspace - close to
the area that requires RF coverage. Typical coverage (dependent on conditions) is around
60m per receiver, boostable to 90m if an external RF aerial is used. See Radio Receivers,
page 7, for more detailed information.
