Analogue Addressable Fire Alarm & Detection System
- Digital protocol
- Automatic address with patented XPERT card
- Alarm address provides for fast & exact location of fire
- Aesthetic appearance with intelligent devices
 |
Addressing & Communication :
Each device responds to interrogation & command from central control equipment. It communicates to the panel-information on status, command bits, type, location and other informations that allows an alarm to be raised even when the device is not itself being interrogated. Message error checking is also provided. The detectors provide an alarm facility that automatically puts an alarm flag on the data stream & reports its address when the pre-set EN54 thresholds are exceeded. All the electronic components are in the detector but the location - information is held in the base with the help of a patented XPERT card, which eliminates, the risk of addressing-errors during maintenance and service. |
 |
System configuration :
The choice of detectors from our range follows, well established principles of system design, that is, the optimum detector type will depend on the type of fire risk and fire load, and the type of environment in which the detector is sited. |
| |
 |
Intelligent Fire Detectors :
For general use, smoke detectors are recommended since these provide the highest level of protection. Smoke detectors from our range may be lonisation, Optical or Multisensor types. It is generally accepted that lonisation types have a high sensitivity to flaming fires, widely used for property protection whereas Optical detectors have high sensitivity to smouldering fires, widely used for life protection. |
| |
 |
The Multisensor is basically an Optical smoke detector and will therefore respond well to the smoke from smouldering fires. This detector also senses air temperature. This temperature sensitivity allows the Multisensor to give a response to fast burning (flaming) fires, which is similar to that of an lonisationdetector. The Multisensor can therefore be used as an alternative to an lonisation detector.
Where the environment is smoky or dirty under normal conditions, a Heat detector may be more appropriate. It must be recognized, however, that any Heat detector will respond only when the fire is well established, generating a high heat output. |

MOUNTING
BASE
There are four
double
terminal and
one single
terminal to
isolate and
provide
continuity of
an earth or
shield.
These are Zero
Insertion
Force Bases,
particularly
useful while
fitting on
suspended
ceilings.

20D
ISOLATING BASE It senses and
isolates short
circuit faults
on loops &
spurs. The
base is loop
powered,
polarity
sensitive and
accepts the
XPERT card to
set the
associated
device
address
|
XPERT CARD
A unique
patented XPERT
card provides
simple, user
friendly and
accurate
identification
of detector
location
whereby a
coded card,
inserted in
the base, is
read by any
detector once
it is plugged
in. |
|
 |
 |
 |
|
MANUAL CALL
POINT
When operated
it
interrupts the
polling
cycle and
reports its
address in
less than a
second. |
ISOLATORS
'Stand-alone'
isolators,
which have
their own
bases, may be
used instead
of isolating
bases. The
isolators are
wired to a
loop between
detectors or
other devices. |
LOOP-POWERED
SOUNDERS
There are two
types of loop
powered
sounders
available, one
ceiling-mounted
(85dB) and one
stand-aone
(100 dB). |
