There may be false alarm in the alarm system. The Ministry of Public Security allows the alarm system to have a certain false alarm rate. The false alarm mainly comes from the infrared probe. Door magnet and host have no problem of false alarm, so when we install infrared probe, we should install it strictly according to the regulations, so as to minimize the false alarm rate.

The alarm system is not allowed to fail to report. In order to make the alarm system work well, please pay attention to whether or not the probe is well powered. If there is a weak current indication, please replace the battery in time.

How do you know it's time to change batteries?
When the power is insufficient, the power indicaticator light on door magnet and probe will be lit on. The low battery report will be sent to the alarm host.

Would the alarm work if the windows weren't closed?
Door/window magnetism will fail, but the probe can work as usual, so it is better to use double protection of door/window magnetism and probe.
