375. Installation instructions5.1 InstallationProceed as follows when installing the accessory module:Determine the best possible installation location. This should beselected so that good wireless communication between thecomponents is guaranteed. We recommend using the wirelesstesting box for determining the installation location.Note: Select the installation position so that the assembly moduleis positioned within the monitored range of a detector. Make surethat the accessory module is installed as high as possible – at least1 metre above the ground.The device must not be installed in the following locations:- In protected or unprotected outdoor areas- Within 1 metre of electronic equipment and lines, such ascomputers, photocopiers, LAN and high-voltage or three-phasevoltage linesAfter deciding on the place of installation, open the housing of theaccessory module and first remove the PCB from the rear side bycarefully bending the upper PCB holder upwards until the PCB canbe removed.Using the rear housing side as a template, mark the fixing holes onthe wall. Fix the accessory module to the wall, but do not tighten thescrews yet.Connect the cables in the accessory module as shown on thefollowing pages. Ensure sufficient tension relief for the cables inthe accessory module.Replace the PCB and tighten the screws.Carry out the necessary programming (see point 7).Following successful programming, the piezo signaller on theaccessory module beeps at short intervals. Replace the cover atthis point, then close the casing.After about 5 seconds, the piezo signaller emits a double tone andconfirms the programming. If the housing is opened again, atamper alarm is sent to the wireless alarm system.5.2 Connecting the power supplyThis diagramshows the connection of theaccessory modulewith the 12 V DC power supply.nit.
