## Summary description

Evolveo ACS MST is a wireless opening detector designed to detect door or window openings and provide tamper protection. It connects wirelessly to compatible alarm systems and triggers alerts when a contact is broken or tampering is detected. Suitable for home and small-business security, the compact detector enables easy installation on doors and windows and adds an extra layer of perimeter protection.

## Long 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

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.
