Honeywell FG1625SN Wired Glass Break Detector
The Honeywell FG1625SN is a wired acoustic glass break detector engineered for commercial and industrial perimeter protection. It integrates directly into Honeywell VPLEX security control panels and detects the distinctive acoustic signature of breaking glass — providing reliable intrusion detection for windows and glass doors without the maintenance burden of battery-powered alternatives.
Key Features
- Wired Connectivity: Direct hardwired connection to VPLEX control panels eliminates battery replacement cycles and ensures continuous availability. No periodic testing or power-up latency — the detector remains armed and responsive 24/7 without power-budget constraints.
- Acoustic Glass Break Detection: Monitors the specific sound frequency pattern of tempered and annealed glass breakage. This acoustic approach avoids false triggers from vibration, wind, or structural noise common in warehouse and manufacturing environments.
- VPLEX System Integration: Pairs directly with Honeywell VPLEX platforms — no protocol conversion or third-party gateway required. Simplifies panel wiring, reduces commissioning time, and maintains full system visibility within your existing Honeywell command center.
- Commercial-Grade Reliability: Designed for industrial facilities, warehouses, and commercial buildings where perimeter integrity is critical. Wired architecture means no signal dropout due to interference or range limitations.
- Low Maintenance Footprint: Without batteries, there is no scheduled replacement cost, no disposal compliance, and no risk of dead-battery lockout during an intrusion event — a real advantage in facilities with hundreds of detection points.
Integration and Compatibility
The FG1625SN is purpose-built for Honeywell VPLEX security systems and compatible Honeywell control panels. Wired installation via standard security zone wiring provides the stable, low-latency signal path required for time-critical perimeter detection. When integrated with a properly configured network video recorder and IP cameras, glass break detection can trigger automatic video capture and alerting — creating a closed-loop response to intrusion attempts.
Installers familiar with Honeywell hardwired systems will recognize the FG1625SN's zone-based provisioning model. It supports standard alarm panel input formatting and integrates without custom drivers or firmware updates.
When to Choose a Different Model
If your facility already uses wireless-only Honeywell panels or a different vendor's ecosystem (such as access control systems from a third party), verify compatibility before ordering — VPLEX-specific wiring is not backward-compatible with all Honeywell product lines. For outdoor glass surfaces exposed to extreme vibration (heavy machinery, blast zones), consider consulting with a Honeywell field engineer to confirm acoustic sensor placement and sensitivity tuning; glass break detectors may require repositioning to avoid environmental noise saturation.
Frequently Asked Questions
Q: Is the FG1625SN compatible with all Honeywell control panels?
A: The FG1625SN is designed for Honeywell VPLEX systems and compatible panels. Verify your panel model in the Honeywell documentation before installation — not all Honeywell panels support the same wiring protocols.
Q: Does the FG1625SN require batteries?
A: No. The FG1625SN is fully wired and draws power directly from the control panel. There are no batteries to replace, test, or manage.
Q: Can the FG1625SN trigger video recording on an NVR?
A: Yes, when paired with a control panel that supports alarm output triggering and connected to a compatible NVR or video management system via relay or IP integration. This allows synchronized recording during glass break events.
Q: How is the FG1625SN mounted?
A: Mounting varies by installation — consult the Honeywell datasheet for recommended placement near windows and glass doors. Acoustic sensors should be positioned to detect breakage while avoiding placement directly adjacent to HVAC vents or machinery that generates continuous noise.
Q: What is the warranty on the FG1625SN?
A: Standard Honeywell commercial security equipment typically includes a 1-year manufacturer warranty. Confirm warranty terms at purchase from your specialty reseller.
Q: Does the FG1625SN work with wireless monitoring systems?
A: No. The FG1625SN is a wired detector and must be connected to a VPLEX or compatible hardwired control panel. Wireless integration would require a compatible wireless-to-wired interface module, if available.

The Honeywell FG1625SN solves a real pain point in hardwired security: detecting glass breakage reliably without the maintenance overhead of battery-powered sensors. Wired acoustic detection is the right tool when you're protecting a perimeter with dozens of windows — zero battery lifecycle, zero power-budget negotiation with the panel, and direct integration into VPLEX without protocol middlemen.
Technical Highlights:
- Wired Power and Signal: Eliminates battery replacement cycles entirely. The FG1625SN draws power and communicates via the panel's hardwired zone interface — no supervision latency, no RF interference, and no blackout risk from dead cells.
- Acoustic Signature Detection: Monitors the specific frequency fingerprint of glass breakage rather than generic vibration or shock. This dramatically reduces false alarms in industrial settings where machinery vibration is constant background noise.
- Direct VPLEX Integration: No gateway, no translation layer, no protocol conversion — the FG1625SN speaks native Honeywell zone language, which cuts commissioning time and troubleshooting surface area.
Deployment Considerations:
- Acoustic Placement Matters: Sensor positioning is critical in high-vibration environments. HVAC ducts, machinery, and heavy traffic noise can degrade detection sensitivity if the sensor is poorly placed. Plan mounting locations during the site survey, not during rough-in wiring.
- VPLEX-Only Ecosystem: If your facility is mixed-vendor or you've standardized on a different Honeywell panel line, this detector won't integrate. Compatibility must be verified before procurement — there's no workaround for wired-only architecture.
- Relay Output Synchronization: To tie glass break detection to video recording, you need a panel with relay outputs or IP alarm integration capability. A standalone FG1625SN on a basic panel will only generate a local alarm — no remote capture without additional infrastructure.
Position the FG1625SN as the perimeter anchor for mid-sized commercial and warehouse deployments where VPLEX is already the standard and battery maintenance is a budget drain. It's not a retrofit solution for wireless-first sites, but it's the right choice for hardwired facilities that prioritize uptime and zero-touch operation.
