How to choose
In the Bosch Wireless Fire Detection System, detectors and call points talk by radio to an FWI-270 radio gateway instead of being wired back. The area the gateway serves is called a radio cell, and each device can be mounted anywhere inside it. The gateway handles up to 30 radio devices and uses multihop mesh technology: messages travel over at least two independent paths and can pass through up to two intermediate stations, which extends the range.
Every device runs on a BAT3.6-10 lithium battery pack (3.6V, 10 Ah) that is ordered separately; Bosch gives a typical battery life of 3 years for the call points. The FDOOT271-O radio fire detector also needs the FDB271 base, and the FDME273-O call point needs the FDMH273-R housing, both ordered separately.
For manual call points, choose by how the alarm is raised. On the FDM275-O the alarm is triggered directly by pressing the plastic insert and reset with a key. On the FDME273-O the user smashes the glass insert and then presses the alarm button, which is an indirect activation. FPS supplies, installs and maintains Bosch wireless devices in Bhopal and across Madhya Pradesh; confirm the exact part numbers with FPS before ordering.
