Security and fire sensors for GSM Alarm Security, magnetic contact sensors are designed for mounting on doors, gates, windows, etc. This type of sensor consists of two parts, performed in identical packages, one housing is a magnet in the other reed. Work data sensors on opening as soon as the magnet moves away from the reed 2 – 5 cm (depending on sensor type) contact opens the reed, creating an alarm. lready – you may have come to the same conclusion. When installing the necessary consider the following factors that affect the sensors. 1. Reed usually mounted on the stationary part of a door or window, and the magnet on the moving blade, although in some cases, you can set and vice versa. 2.
The gap between the magnet and reed should be between 2 and 6mm. It is important that the magnet and reed switch are on the same axis, especially, true for sensors hidden (inside) installed on metal doors. 3. It is advisable to install the sensor at a distance of no more than 25 cm from the solution by leaf, in its upper part, opposite the hinges. 4. When installing the sensors should be aware that by impact or other physical effects of the reed bulb can razgermetizirovatsya (destroyed). Sensors IR 102-2 (QMS 1), IO 102-16 (SMC 16) are designed for installation on an open structure of wood, plastic, aluminum alloys. IO102-5 sensor (SMC 5) is designed for flush mounting on the above listed construction for its installation must drilled holes of 9mm. Sensor IR 102-6 (SMC 6) is designed for flush mounting on metal doors.
