Monitor the open/closed status of a door or other open/close object with the Qolsys IQ Wireless S-Line Encrypted Mini Door/Window Sensor (AKA the IQ Mini-S). Used with any compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.) or a Qolsys IQ Panel, this wireless battery-powered sensor sends intelligent notifications to your panel, such as "door left open". Notifications can be custom-named, so you can know exactly what's going on, such as "front door left open". For each sensor, you can also determine a unique chime type and turn voice prompts On/Off. Additionally, the sensor can be included in automation rules. For example, you could create a rule that adjusts your thermostat when a door is left open. FEATURES: Compatible with 319.5 MHz wireless panels, such as GE/Interlogix or Qolsys IQ. Wireless range up to 600 feet from panel. "S-Line" encryption protects signals. Using Alarm.com (requires optional subscription), you can get a text if your door or window is left open. Triggers alerts for tamper, tamper restore, alarm, alarm restore, and low battery. The sensor consists of two components: the sensor and the magnet. The sensor installs on the door/window frame, and the magnet installs on the door/window itself. When the sensor detects the magnet has moved more than 1 inch, a notification is triggered. CONTENTS: Sensor, Magnet, Batteries, Adhesive, Instructions. NOTE: Requires connection to a compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.), Qolsys IQ Panel, Leviton 64-Zone Receiver for GE/Interlogix, Elk M1 Wireless Receiver for GE/Interlogix Crystal Transmitters, or other legacy 319.5 MHz system (all sold separately).
