Two-wire fire alarm detector

by Mark Rowe

Fike Safety Technology has introduced a new detector for its TWINFLEXpro intelligent two-wire fire alarm. The Multipoint ASD detector has all of the features of the existing detector, including seven modes of detection and optional built-in sounder, and new features. The new detector includes an optional integral strobe, allowing the two-wire installation of a smoke-heat detector, sounder and strobe, in a single device.
The detector incorporates a new optical chamber for smoke detection and an LED in the base, which flashes when the detector head is removed. This enables users to identify which detector is missing even from a distance, as in a high-ceiling building. As for testing and maintenance at height, the new head is fully compatible with the Solo Detector Tester pole.

The whole system can be installed using only one pair of wires per zone – installation savings can be as high as 40 per cen the makers claim. As the product offers seven modes of detection, one device suits all applications it is claimed. The product has the ability to differentiate between call point and detector alarms; can accommodate up to 32 devices per zone; has a separate fault monitoring display for each zone; has a man walk test facility and allows zones to be configured without the need for resistors or capacitors. Fike can also provide a special Output Unit. This can be anywhere on the zone circuit and is for connecting to equipment such as plant shut-down controls and door release mechanisms.

Checkpoint Alarm Confirmation for use in Houses of Multiple Occupancy (HMO) is a configurable pre-alarm that can be set on detectors in dwelling areas that allows time to investigate the cause of the alarm before building-wide evacuation is initiated. This can the company adds reduce the disruption from nuisance alarms.
