Incorporating the Multipoint detector with built-in
sounder means the whole system can be installed using only one pair of
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 required. 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
All Twinflex Systems have the ‘Checkpoint’ alarm confirmation feature drastically reducing false alarms.
Repeater panels are also available for the Twinflex system, which
