IS-280CM | Honeywell 360° ceiling-mount passive infrared motion detector

Honeywell · HMIs & Displays

Description The Honeywell IS-280CM is a commercial ceiling-mounted passive infrared (PIR) motion detector designed to provide full 360° coverage in indoor security applications. This part number uses an advanced microprocessor and a precision-tested pyroelectric sensing element to deliver accurate motion detection with strong false-alarm immunity. Its low-profile housing and wide coverage range make it suitable for offices, retail spaces, and open areas requiring reliable motion monitoring.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Security Part Number IS-280CM Subcategory Security Motion Detector Detection Method Passive Infrared (PIR) Coverage Area 360°; 14 m (46 ft) diameter Detector Zones 50 PIR fields of view Operating Temperature 14°F to 122°F (-10°C to 50°C) Relative Humidity Up to 95% RH, non-condensing Dimensions 125 mm Ø × 38 mm H (4.9" Ø × 1.5" H) Alarm Relay Output Form A, SPST, 30VDC 500 mA Tamper Switch N.C., 24VDC 50 mA Pulse Count Options 1, 2, 3, or 4 pulses Detection Speed 0.2–5.0 m/s (0.5–15 ft/s) Warm-Up Period 35 ± 3 seconds Power Requirements 9–30VDC or 7.5–24VAC Current Draw 17 mA max at 12VDC Alarm Indicator Red LED (selectable on/off) Mounting Height 8–12 ft ceiling mount     Information About IS-280CM The IS-280CM is part of Honeywell’s ceiling-mount PIR sensor family, designed for broad-area coverage from a compact and aesthetically neutral enclosure. Its construction incorporates a 50-zone optical layout and a microprocessor-based signal algorithm that enhances detection accuracy and environmental stability. The detector integrates easily with commercial security panels using Form A relay outputs, tamper protection, and selectable pulse count settings. Common applications include office spaces, open rooms, and cubicle environments where 360° passive infrared detection ensures comprehensive occupancy sensing and intrusion monitoring. Key Features: 360° detection pattern: Provides wide-area motion coverage up to a 46 ft (14 m) diameter. Advanced microprocessor processing: Improves detection accuracy while reducing false alarms. 50-zone PIR optical system: Enhances sensitivity and ensures consistent coverage across the monitored area. Selectable pulse count: Adjustable from 1–4 pulses to match application requirements and reduce nuisance trips. Integrated tamper switch: Protects against unauthorized removal or tampering. Visible walk-test LED: Enables simple installation and verification of detection coverage. Supports multiple power types: Operates from 9–30VDC or 7.5–24VAC for flexible system integration. Low-profile ceiling-mount design: Blends into commercial spaces and supports both surface and recessed wiring. The IS-280CM delivers the reliability and precision required for commercial passive infrared motion detection systems.
