PENTATECH Pressure mat Indexa Black 95 dB 33620

This pressure mat sounder combo safeguards doors in an effective and unobtrusive manner. Just put it under the doormat or carpet. Mat and sounder are connected by a thin 30 ft (10 m) cable. Means you can place the sounder wherever you like. Also suitable for corridors or passageways. Sounder settings include a loud alarm signal as well as a chime with two volume levels (high/low). May also be used as a cat door bell. Your cat stepping on the mat placed at a closed front door or French window triggers a chime. Only for use in dry areas. Must not be exposed to rain or water.
