2. Power supply Connect the lithium battery making sure it is the right way round. Ò The red LED flashes for 15 sec, then once every 10 sec to indicate that the detector is working normally. 3. Recognition programming iMPoRtAnt: during recognition programming, the product to be programmed for use with the control panel does not need to be placed next to it.
4. Installing the detector Make sure there is a distance of at least 2 m between each product, except between two detectors. 4.1 Choosing the best place iMPoRtAnt: the heat detector is not supposed to replace smoke or gas detectors to ensure the safety of people against smoke or gas, and notably in rooms such as bedrooms, playrooms and other living areas.
• in rooms where the relative humidity might 4.2 testing the radio range rise above 95% (without condensation), at the chosen location • close to heating, cooling or air vents. iMPoRtAnt: the control panel must be in installation mode to perform this test (see Mounting examples: Recognition programming).
4.3 Fixing the detector in place Align the 2 locating arrows marked on the mounting Standard fixing method base and the detector, then 1. Install the base in the desired location, then mark the lock the unit by turning position of the 2 fixing holes (marked ) using a clockwise.
fire detectors installed in the home. iMPoRtAnt: 155-21X heat detectors can only be connected with the same type of detectors: e.g. a 155-21X can be connected with 155-21X heat detectors or 151-21X smoke detectors. You can therefore be sure of being warned if smoke is detected in a room far away from the room in which you are in.

5. Testing the detector Although alarm sounding is reduced during a iMPoRtAnt: you can recognise this heat manual test of a heat detector, it is advisable detector by the white slots in the detection to inform neighbours beforehand and to use head.
