The FW841 conventional zone module is intended to allow Maple Armor intelligent fire alarm control panels to interface and monitor 2-wire conventional detectors in retrofit applications.
The initiating zone can support a mix of 2-wire conventional automatic detectors as well as normally open dry contact alarm initiating devices such as mechanical heat detectors and manual stations.
The Initiating Zone power can be derived either from the SLC loop or be provided by an external UL/ULC listed 24VDC power supply.
