Product information

Description

Evolveo ACS MST is a wireless opening detector designed to expand an alarm system by detecting the opening of doors or windows. It pairs with compatible alarm control units and includes tamper protection that triggers an alarm and can send an SMS when the unit is intentionally tampered with (requires EVOLVEO Alarmex). The compact device is intended for indoor mounting and offers a transmission range of approximately 80 meters in open space.

Advantages

The detector provides immediate response when the protected contact is separated, triggers alarm when the two parts are moved apart by more than 2 cm, and resists false alarms caused by vibrations or wind. It features tamper detection, compatibility with EVOLVEO Alarmex and EVOLVEO Sonix systems, an LED low-battery indicator, and an elegant modern design. Powered by two CR2032 batteries with an expected battery life of about one year depending on usage.

Suitable for

Monitoring doors in homes and apartments
Securing windows against unauthorized opening
Supplementing small-business perimeter security

How to use

Mount the detector on the door or window frame and align the magnet part with the main sensor so the two parts are within the specified gap when closed. Pair the detector with the main alarm unit according to the alarm system’s pairing procedure (for example EVOLVEO Alarmex or Sonix). Install two CR2032 batteries, check the LED indicators, and test the device to confirm correct response to opening and tamper events.

Usage recommendations

Install the detector indoors, avoid placing it where repeated strong impacts or moisture occur, and test battery status regularly. For tamper alarm and SMS notifications, use with EVOLVEO Alarmex. Ensure the installation location keeps the two parts aligned within 2 cm when closed to prevent false alarms.
