The JA-181M is a component of Jablotron’s alarm system. It is designed to detect the opening of doors, windows etc. 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 CT-01 ratchet-wheel movements. Small movements are filtered out so that wind blasts do not cause false alarms. The JA181M can be used with the LD-81 flood detector as well.
