Alarm Systems fall broadly in to
two groups - Conventional Systems or Analogue Addressable Systems.
'Conventional' Fire Alarm Systems, in their
various forms, have been around for many years and have changed
little in that time in terms of technology although design and
reliability have improved significantly. However, Conventional fire
alarm Systems are a well-proven technology protecting many hundreds
of thousands of properties worldwide. A Conventional Fire Alarm
System is often the natural choice for smaller systems or where
budget constraints exist.
Incorporating the Multipoint detector
with built-in sounder means the whole system cab be installed using
only one pair of wires.
Using the Multipoint detector as part of
the Twinflex 2-wire fire alarm system means that when a detector is
wired in, a sounder is too - with no extra wiring. This greatly
reduces the number of points that need to be installed and the time
it takes to install them.
As the Multipoint offers 7 different
modes of detection, the installation is made even simpler as this
one device suits all applications. Whatever type of detection is
required, for any part of the installation, it can be selected by
the flick of a switch at the time of commissioning. Any one of the 3
different smoke modes, 2 fixed temperature heat modes, a rate of
rise mode and a combination smoke or heat mode can be selected.
As the Multipoint detector is available
with or without a full specification 92dBA sounder (for only a
marginal cost difference) no extra devices need to be purchased when
audible warning is required (meets audibilty levels recommended in
BS5839 Part 1: 1988). Twinflex callpoints can be run on the same
pair of wires as detectors. Further cost savings can be utilised by
using the new combined callpoint / sounder. Both detectors and
callpoints have a selectable EOL module so any device can be set as
the end of line monitor. The panel can also differentiate between
callpoint or detector alarms.
|If extra sound is required, or
for areas that do not require detection, then the Hatari
Sounder can be used on the same two wires, offering sound
output of 100dBA. It also has a built-in EOL monitoring
The panel can
accommodate 32 devices per zone, has separate fault
monitoring displays for each zone, and a one man walk test
facility. Zones are configured without the need to use
resistors or capacitors on unused zones.
- Two wire installation - only one
circuit per zone to connect detectors and sounders.
- Installation savings as high as 40%
- save on cable, installation time and sounders.
- Callpoint identification - panel
can differentiate between callpoint or detector alarms.
- Built-in end of line device - all
devices including detectors, callpoints and stand-alone sounders
have a selectable built-in end of line monitoring function. No
resistors or extra circuits required.
- No base diode requirement.
- Multipoint detector provides 7
modes of detection.
- System fully complies with BS and
- 32 devices per zone.
- Easy to install - no need to worry
about marking "in's" and "out's".
- Available with 2,4 and 8 zone
- 8 and 16 zone repeater panels
- 72 hour standby.
- Auxiliary sounder circuit.
- Output module for plant switching,
door release etc.
