The RF interface module is surface-mounted. The cables can be surface-mounted or flush-
mounted. For this reason, pre-punched openings are provided on the lower part of the
housing (on the sides and the base). The pre-punched openings can be punched out more
easily, if the PC board is first removed.

Installing DOW 1171 RF Smoke Detector

Notice!
Do not connect the batteries in the RF smoke detector base until the RF interface module is
permanently connected to the power supply. If this is not the case, the detector constantly
tries to establish a connection to the RF interface module, which substantially reduces the
service life of the batteries.
