Honeywell Home Intrusion 5821 Wireless Temp Flood Transmitter

Product Description

The HONEYWELL HOME INTRUSION 5821 is a wireless temperature and flood transmitter designed for use in residential and light commercial security and monitoring systems. It serves a dual function, detecting both water presence and out-of-range temperature conditions, then transmitting alerts wirelessly to a compatible control panel or receiver. Licensed alarm installation technicians are the primary installers of this device. Its selectable configuration allows the technician to tailor the transmitter behavior to the specific monitoring application on site, making it a flexible option for environments where both flood and temperature hazards are a concern.

The 5821 is suited for installations in areas prone to water intrusion or temperature extremes, such as mechanical rooms, basements, utility closets, and crawl spaces. It is typically deployed as part of a broader wireless intrusion or environmental monitoring system. The selectable transmitter mode allows field configuration to match the detection scenario, whether the priority is flood detection, temperature monitoring, or both simultaneously.
