Two Wire Fire Alarm System

Multiflex Manual Call Points can be run on the same pair of wires as detectors. Both detectors and Manual Call Points have a built in EOL switch so that any device may be set as the end of line monitor. The panel can also differentiate between a Manual Call Point and a Detector alarm. If extra sound is required, or for areas that do not require detection, then the Multiflex sounder may be used on the same two wires, offering sound output of 100dB(A). It also has a built in EOL monitoring switch. The Multiflex conventional fire alarm system incorporating the Multiflex combined smoke and heat detector with built in sounder means the whole system can be installed using only one pair of wires. The panel can accommodate up to 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.

Using the Multiflex detector as part of the Multiflex 2-wire fire alarm system means that when a detector is wired in, a sounder is wired in too – with no extra wiring, thereby greatly reducing the number of points that need to be installed and the time it takes to install them.

As the Multiflex 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 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 Multiflex Multipoint detector is available with or without a full specification 90 dB(A) sounder (for only a marginal cost difference) no extra devices need to be purchased when audible warning is required. (Meets audibility levels recommended in BS5839 Part 1:1988).
