Honeywell 5853 Wireless Glass Break Detector

Honeywell 5853 is a battery-powered wireless glass-break detector that listens for breaking or impacted glass and reports fast, reliable alarm signals with high false-alarm immunity.

This compact Honeywell Home (Resideo) 5853 detector uses an advanced FlexCore™ signal processor built on an ASIC to analyze sound data in parallel, improving detection speed and accuracy. Designed for both professional alarm systems and homeowner upgrades, the unit detects many glass types — from plate and tempered to laminated and wired glass — while minimizing nuisance alerts. It combines a low-profile housing, tamper protection, and long battery life to fit modern security installations.

How does the 5853 actually detect broken glass?

The detector captures acoustic signatures associated with glass impact and shattering, then runs those signals through the FlexCore™ ASIC for rapid pattern analysis. Parallel processing helps the unit distinguish real glass-break events from ordinary household noises.

• Acoustic microphone tuned for glass frequencies
• FlexCore™ ASIC processes sound data in parallel for quicker recognition
• Four selectable sensitivity levels to match the protected environment
• Recognizes multiple glass constructions including laminated and wired

Where should I place the wireless glass-break detector for best results?

Mount the 5853 in a central position with a clear line of sight to the protected windows or glass doors; typically ceiling or high wall locations work best. Avoid placing it directly behind heavy drapery, inside cabinets, or near loud appliances that could mask glass sounds.

• Ceiling or high wall aimed at primary glass panes
• Coverage radius optimized when unobstructed by curtains or shelving
• Not recommended inside enclosed cabinets or behind thick fabrics
• Adjust sensitivity depending on room size and ambient noise

What installation and maintenance should I expect?

Installation is straightforward for technicians familiar with wireless alarm components, and the detector supports case tamper on both front and back for added security. Batteries are easily replaceable and rated to last about ten years under normal use, reducing long-term maintenance hassle.

• Front and back case tamper switches included
• Ten-year battery life with user-replaceable batteries
• Remote test mode available with FG-701 tester (sold separately)
• Selectable sensitivity (Max, Medium, Low, Lowest) for tailored setup

How does this detector integrate with alarm systems?

The 5853 is designed for compatibility with Honeywell/Resideo wireless security panels and other supported receivers. It communicates alarm and tamper events over the system’s wireless network, enabling central monitoring and automated responses through the control panel.

• Works with Honeywell/Resideo wireless alarm systems and compatible receivers
• Reports both glass-break events and tamper conditions to the panel
• Test mode helps verify enrollment and range without triggering full alarms
• Selectable sensitivity settings reduce false trips in shared living spaces

Who is this for: The Honeywell 5853 Wireless Glass Break Detector is aimed at homeowners, property managers, and security professionals who want a discreet, dependable glass-break sensor with strong false-alarm rejection and minimal upkeep. It suits installations where acoustic detection is preferred over contact sensors — for example, glass doors or windows that are difficult to wire, multi-pane or laminated glazing, or rooms where aesthetics call for a low-profile wireless device.
