Honeywell 5821PB-KT1 Wireless Combo Temperature/Flood Kit
Overview
The Honeywell 5821PB-KT1 is a wireless combo kit that pairs temperature and flood detection sensors for integration into Honeywell security and environmental monitoring systems. This accessory is designed for property managers and security integrators who need to monitor environmental hazards (water intrusion, freezing temperatures) in addition to physical access — basements, mechanical rooms, server closets, and wet areas where water or temperature excursions trigger costly damage or downtime.
Compatibility
The 5821PB-KT1 integrates with Honeywell wireless security control panels and environmental monitoring ecosystems that support the manufacturer's wireless sensor protocol. Confirm compatibility with your specific Honeywell control panel model number before deployment. Works with Honeywell residential and light commercial security systems that support wireless accessory expansion.
Installation Notes
Wireless sensors require clear line-of-sight to the control panel receiver or repeater module. Mounting surfaces must support sensor bracket attachment; verify wall or surface material compatibility. Battery replacement intervals depend on sensor duty cycle and RF environment — plan for annual or biennial battery service in high-interference areas. Test wireless range (typically 40–100 feet in open space) before final installation to confirm signal strength through walls and structural obstacles.
