Fike 204-0003-B multipoint ASD detector, Black

Please note: this is a non-returnable item (excluding faulty goods)

Fike 204-0003-B is a multipoint ASD detector.

The Fike 204-0003-B TWINFLEX Multipoint ASD Detector (Black) is a 2-wire device used with the TWINFLEX and TWINFLEX Pro systems. The TWINFLEX two-wire Multipoint ASD detector can be set to any one of 3 smoke modes, 3 heat modes, as well as a Combined Mode (Smoke 2 and Heat 2) where a smoke or heat source can trigger a fire decision – see below. All TWINFLEX products, including the Multipoint ASD detector, feature an End of Line switch, removing the need for end-of-line resistors.

The Multipoint ASD detectors have the unique benefit of an optional full specification integral sounder, where 90dBA output can be achieved. The two-wire Multipoint ASD detector can be set to 3 different sound patterns, as well as switched off, with 2 sound output levels. All Multipoint ASD detectors have the option of an integral combined strobe.

To ensure the detection capabilities of the detectors are never compromised, they self-calibrate every 6 hours. They also continuously monitor for dust contamination until, depending on the environment, it reaches a point where the chamber becomes saturated. Before this can develop into a false alarm situation, the panel will indicate that the device in question requires attention.

Modes of Detection

Smoke 1: Used where ionisation detectors are normally fitted, especially when there are high ceilings or a risk of free-burning fires (chemical stores etc.) or fires that need to be detected extremely quickly. Smoke 2: Used where optical detectors are normally fitted, when there is a risk of a smouldering fire and for escape routes. Smoke 3: Designed for use in areas that are prone to nuisance alarms.

The reduced sensitivity linked with a time delay feature means that a higher concentration of smoke needs to be present for a constant time period before a fire decision is made. For example, this setting is ideal for hotel bedrooms with en-suite shower rooms. Heat 1 (Rate of Rise): Used where a standard rate of rise detector would normally be used.

Heat 2 (Standard Fixed Temperature – 58ºC approx.): Used where a standard fixed temperature heat detector would normally be fitted, suitable for kitchens etc. Heat 3 (High Fixed Temperature – 90ºC approx.): Used where a high fixed temperature heat detector would normally be fitted. Suitable for commercial kitchens, boiler rooms etc.
