Qolsys Inc QS1136-840 Wireless Door Window Contact

Product Description

The QOLSYS INC QS1136-840 is a miniature wireless door and window contact sensor finished in brown. Designed for surface-mount installation on doors, windows, and other entry points, it transmits an open or close signal to a compatible security panel when the contact pair separates or reunites. The compact form factor keeps the sensor low-profile on finished trim and cabinetry. Security technicians and low-voltage alarm installers are the primary trade installing this device. Its brown finish is intended to blend with wood frames and darker trim common in residential and light commercial settings.

This contact sensor is suited for residential and light commercial security installations where a discreet, wireless sensor is preferred over hardwired alternatives. It is appropriate for monitored entry points including hinged doors, sliding doors, double-hung windows, and casement windows. The wireless design eliminates the need to route signal wire through door frames or window jambs, reducing installation time and finish damage. It is part of the IQ Mini sensor family and is intended for use with compatible QOLSYS IQ security panels.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with applicable local codes and the panel manufacturer's wiring and enrollment guidelines. Power down or disarm the security panel before enrolling new sensors to avoid false alarm triggers. The sensor and magnet should be mounted so the gap between them does not exceed the manufacturer's specified activation distance. Avoid mounting on metal surfaces that may interfere with wireless signal transmission.
