The wireless alarm system features an integrated GSM telephone dialer with emergency call and hands-free functionality. The package includes numerous sensors in addition to the base station, and the set can be expanded with additional sensors to a maximum of 32 sensors. Break-ins are a true nightmare. The built-in siren of the Olympia Alarm System Protect 9868 Smart Home serves as an effective deterrent against intruders. If a break-in does occur, the telephone alert allows you to take appropriate action even when you are away. This way, you can call for help and fend off an intrusion. The Olympia Protect 9868 Smart Home alarm system is easy to install. Thanks to wireless technology at 0.868 GHz, no wiring or drilling is required. The operation of the system is straightforward and intuitive. The sensors are integrated into the system using a plug-and-play method. Wall mounting is possible. With the mobile ProCom app for Android (from 4.4) and iOS smartphones (from 7.0), you can conveniently control your Protect alarm system's base from anywhere using your smartphone or tablet. When the installed sensors trigger an alarm, the signal is transmitted wirelessly to the base unit. This unit sounds an acoustic alarm with its built-in siren or sends a notification to selected, programmable phone numbers. Up to 10 phone numbers can be programmed. If a line is busy, the next number is automatically dialed. The wireless Olympia Protect 9868 Smart Home alarm system can be configured in 6 modes: Alarm mode, Silent mode, Home mode, Disarmed mode, Room monitoring, and Hands-free calling from external phones. The color of the LCD display, which features a 13-digit numeric and alphanumeric keypad, is blue or yellow depending on the alarm status. The base unit is secured against power outages.
