The Honeywell IS335 is a wired PIR motion detector designed for reliable intrusion detection in residential and light commercial security systems. It offers a detection coverage of 40 feet by 56 feet, providing a wide area of protection for typical rooms or corridors. This model operates on a 12 VDC power supply and uses a low-current design to minimize wiring requirements. The detector is built with a sturdy ABS plastic housing that resists impacts and tampering. A built-in tamper switch activates if the cover is removed, adding an extra layer of security. The IS335 features a dual-element pyroelectric sensor and a Fresnel lens array that enhances sensitivity while reducing false alarms caused by small animals or environmental changes. The unit includes a walk test LED that can be disabled for covert operation. Installation is straightforward with a standard wall or corner mount bracket, and the wiring terminals are clearly labeled for quick connection to most alarm panels. The hardware is designed for long-term stability, with a temperature compensation circuit that maintains consistent performance across varying climates. Its compact form factor measures approximately 4.5 inches by 3.5 inches by 2.5 inches, allowing it to blend into most interiors without being obtrusive. The detector supports both normally closed and normally open alarm outputs, making it compatible with a wide range of control panels. The IS335 has been tested for electrical noise immunity and meets industry standards for RFI and ESD protection. This model is particularly well-suited for cost-conscious installations where wired connectivity is preferred over wireless to avoid battery changes or signal interference. The build quality reflects Honeywell’s reputation for durable security components, with reinforced screw terminals and a sealed optics chamber to prevent dust accumulation. The unit operates reliably in temperatures from -10°C to 50°C and humidity up to 95% non-condensing. For integrators and system designers, the IS335 offers consistent detection patterns that simplify layout planning. The affordable price point makes it an excellent choice for multi-sensor projects or retrofit upgrades where budget constraints are a consideration. Its simple functionality focuses on core motion detection without unnecessary frills, ensuring that the device does its primary job effectively. The wiring harness is pre-tinned for soldering or crimping, and the included mounting hardware allows for quick attachment to drywall or wood surfaces.

The Honeywell IS335 wired PIR detector balances solid engineering with economical pricing, delivering trusted performance in a straightforward package.
