Description

The red Manual Call Point HFM/153-27D (fi g. A) and the blue Manual Call Point HM/152-27D with lettering „HAUSALARM“ (fi g. B) communicate with the RF Inter- face FUIF511-27D via a secured radio protocol. The plastic case, which is designed in accordance with EN 54-11/B, is provided with an integrated antenna and accommodates the 3.6V lithium battery.

4 data channels in the frequency band 868MHz as well as 20 channels in the frequency band 434MHz are avai- lable for the bidirectional data transmission. The avai- lability of the channel is checked regularly. During the learning phase of the detector, i.e., when the detector is registered at the radio interface, a unique key, based

on a choice of several million codes, is created, which allows the unambiguous identifi cation of the detector. Regular status messages, monitoring of the battery vol- tage and the long life of the included batteries ensure the high reliability of the system.

A built-in LED optically indicates the activated condition of the detector. The hinged door can be opened up to an angle of 180° and it is provided with a replaceable pane of glass. If the detector has been activated, an integrated locking device prevents the closing of the door. When the door is opened, the detector sends a fault message to the radio interface.
