Looking to upgrade or repair your wired home security system? The Honeywell IS3035 is a classic, reliable passive infrared (PIR) motion detector. It has a solid 35-foot detection range, making it great for covering larger rooms, hallways, or garages. A key feature is its pet immunity – it's designed to ignore pets weighing up to 80 pounds, so your dog or cat can wander around without setting off false alarms (though positioning is still important). This is a wired sensor, so it needs to be connected to your existing alarm control panel's wiring, making it a common choice for professional installations or savvy DIYers replacing an old unit. It also includes a tamper switch for security. If you're familiar with Honeywell/Ademco systems, this is a standard workhorse sensor. It's not a wireless or smart home device you control with an app; it's a core component for a traditional hardwired security setup. Always consult with your system's manual or a professional if you're unsure about compatibility, but for the right system, this sensor is a trusted and effective way to detect movement.
