[FPKX15DQ]

This is not a Dual Technology sensor (it has no Microwave)it is a dual element Quad. I normally use this detector when it is not connected to an alarm system but stand alone for
switching something on, buzzer, door bell or the like. It can be used like this because it has a selectable N.O. / N.C relay. 99 % of sensors have a normally closed relay, this one can be switched to normally open if needed making it very versatile at switching things momentarily, or longer via a cheap time latching relay.
