Using the Multipoint ASD detector as part of the TWINFLEXpro² system means that when a detector is wired to the system, a sounder and strobe can also be connected without extra installation time or cost. This greatly reduces the number of points that need to be installed and the time it takes to install. As the Multipoint ASD offers 7 different modes of detection, the installation is made even simpler since one device suits all applications. Whatever type of detection is required, it can be selected by the flick of a switch at the time of commissioning 3 different smoke modes, 2 fixed temperature heat modes, a rate of rise mode and a combination smoke or heat mode. As the Multipoint ASD detector is available with or without a full specification integral 90dBA sounder no extra devices need to be purchased when audible warning is required. If extra sound is required or for areas that do not require detection, then a choice of several different standalone sounders or sounder beacons can be used on the same two wires.
