Overview

Protect entrances and sensitive storage with the IQ QS1135-840 IQ Mini DW-S, a compact S-Line encrypted door/window sensor engineered for professional security and monitoring installations. This IQ-branded magnetic contact transmitter pairs seamlessly with IQ Panel 2 and supports legacy 319.5 signals, making upgrades fast and painless. Installers and facility managers will appreciate the low-maintenance design: it runs on two CR2032 batteries with up to eight years of life and delivers a wireless range up to 600 ft (open air) for flexible placement. The sensor’s tamper switch, move detection (alerts if moved more than 1”), and included rare-earth magnet strengthen intrusion detection while supporting automation through Alarm.com — trigger lights, thermostats or custom notifications like “door left open.” Designed for indoor use on doors, windows, cabinets or safes, the IQ Mini DW-S balances discreet form factor with enterprise-grade encryption and reliability. Ideal for commercial security, retail loss prevention, healthcare monitoring and smart building automation. Add the IQ Mini DW-S to your next security deployment or contact us for bulk and system integration options.
