Jablotron JA-81M door detector
Jablotron JA-81M door detector has a magnetic sensor which activates when a door or window is opened. It can also be extended by a normally closed / normally open sensor. It is also designed to detect the handling of roller blinds. This is achieved by detecting ratchet-wheel movements. Small movements are filtered out so that wind blasts do not cause false alarms.
Can be enrolled to the control panel, to UC and AC receivers (to trigger relays) and to the JA-80L indoor siren (to indicate movement by making a sound)
