Honeywell Home BSM Battery Sense Module

Keep your security and surveillance systems reliable with the Honeywell Home BSM Battery Sense Module, a control panel module built to monitor and protect backup power. The BSM continuously monitors one or two batteries, reporting low-battery conditions and battery removal so integrators and monitoring centers can prevent unexpected downtime and nuisance alarms. With built-in deep-discharge protection that disconnects the battery at a safety threshold of roughly 9.5–10 V, the module preserves battery life and prevents irreversible damage during prolonged AC outages. Designed for quick integration with alarm and access control panels, the package includes the Battery Sense Module, mounting bracket and two battery harnesses to streamline installation and maintenance. Ideal for security installers, facilities managers and monitoring stations, the BSM enhances system reliability and simplifies preventive maintenance for surveillance, access control and intrusion systems. Add the Honeywell Home BSM Battery Sense Module to your control panel deployment to improve backup battery visibility and system uptime — order now or contact us for compatibility details.
