DISPLAYS

Quantec's displays scroll automatically and only show the calls
which are the most urgent plus a message saying how many calls
are waiting on that part of the system. Therefore, if there are
no calls, the displays will show the time, then Staff Presence calls,
Standard calls, Help Required calls, Emergency calls & Attack calls.

INFRARED CEILING RECEIVERS

Infrared ceiling receivers are designed for use with Quantec's wide range of
infrared transmitters (see page 10). They are usually located in bedrooms,
corridors, common rooms and any other internal area that requires infrared
coverage. Slave infrared ceiling receivers are also available (up to three per
master infrared ceiling receiver or infrared call point) to improve coverage in
'L' shaped rooms, etc. Dependent on the type of transmitter(s) used, master
ceiling receivers allow standard and/or attack calls to be made (both levels of
call can be reset by entering a special code at the Quantec Controller or a corridor display). The
type of calls that can be made from a slave ceiling receiver will depend on whether they are
connected to a master ceiling receiver (standard and attack calls only) or an infrared call point
(standard, help required, emergency and/or attack calls).

RADIO RECEIVERS

Radio receivers are designed for use with Quantec's QT412 range of
dual action infrared/radio transmitters (see page 10). Dependent on
the transmitter(s) used, they allow standard and/or attack calls to be made
from external areas such as car parks, loading bays, etc., (both levels of call can
be reset by entering a special code at the Quantec Controller or a corridor display). Receivers
must be mounted internally - typically in a building's roofspace - where they can provide RF
coverage of typically 60m (dependent on conditions/location). An optional RF extension aerial is
available for outdoor use and we recommend this for sites where the receiver is located close to
large metallic objects or thick structural walls. In some cases external aerials can increase a
receiver's RF coverage to typically 90m. For areas such as large car parks, it is not uncommon for
multiple radio receivers to be used (for example, on adjacent walls) to ensure sufficient coverage.
For sites with multiple, separately-managed areas, different radio receivers can be set up to respond
to calls from certain transmitters only. This is done via an RF grouping facility whereby a receiver
in, say, RF group 3, will only respond to transmitters assigned to the same RF group. The default
setting for all radio receivers and transmitters is RF group 1 (of 16).
To help ensure the integrity of Quantec radio receivers, we recommend at
least one monitored RF Integrity Transmitter is used with every radio
receiver. Supplied on a single gang plate, they work by sending a periodic
test transmission to the radio receiver. If the receiver fails to receive the test
signal, it sends a fault message to the Quantec Controller to advise that
