Twinflex 2 Wire Fire Alarm System

Eliminate the problems of false alarms with 'Checkpoint' alarm confirmation.

Repeater panels are also available for the Twinflex system, which use key switch access and have the facilities silence, sound alarms and reset. 

All Twinflex Systems have the 'Checkpoint' alarm confirmation feature drastically reducing false alarms.

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.

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 switch.

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 audibiltiy levels recommended in BS5839 Part 1: 2002). 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.

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.

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.

Incorporating the Multipoint detector with built-in sounder means the whole system can be installed using only one pair of wires.
