1. Introduction
This manual provides comprehensive instructions for the installation, operation, and maintenance of the Honeywell Intellisense FG-1625 Acoustic Glassbreak Sensor. This device is designed to detect the sound of breaking glass, providing an early warning system for security applications. Please read this manual thoroughly before installation and use to ensure proper functionality and safety.
2. Consignes de sécurité
Respectez toujours les consignes de sécurité suivantes :
- Coupez l'alimentation électrique avant toute opération de câblage ou de maintenance.
- L'installation doit être effectuée par un personnel qualifié, conformément à toutes les normes électriques locales et nationales.
- Do not expose the sensor to moisture or extreme temperatures.
- Assurez-vous d'une bonne mise à la terre pour éviter les risques électriques.
- Tenir hors de portée des enfants.
3. Contenu du colis
Vérifiez que tous les éléments sont présents dans le colis :
- Honeywell Intellisense FG-1625 Acoustic Glassbreak Sensor
- Matériel de montage (vis, chevilles)
- Guide d'installation (ce document)
4. Configuration et installation
The FG-1625 sensor is designed for easy installation and can be mounted in various locations to cover all glass types within a 25-foot radius. It features a FlexCore Signal Processor for reliable detection.
4.1 Emplacement de montage
Choisissez un emplacement de montage offrant une vue dégagée view of the protected glass. The sensor can be mounted on walls or ceilings. Avoid mounting directly opposite noisy areas or near air vents that could cause false alarms.

4.2 Instructions de câblage
The FG-1625 is a hardwired sensor. Connect the sensor to your alarm control panel using the following wiring scheme:
- V+ (Red Wire): Connect to the positive power terminal (12V DC).
- V- (Black Wire): Connect to the negative power terminal (Ground).
- C (Yellow Wire): Connect to the Common terminal of the alarm zone.
- NC (Blue Wire): Connect to the Normally Closed terminal of the alarm zone.
Ensure all connections are secure and insulated. Refer to your alarm control panel's manual for specific zone wiring details.
4.3 Ajustement de la sensibilité
The sensor features selectable sensitivity settings to optimize performance for different environments and glass types. Consult the internal dip switches or jumpers (refer to the sensor's internal diagram) to adjust sensitivity. Test the sensor after adjustment using a glassbreak simulator to confirm proper operation.
5. Fonctionnement
Once installed and powered, the FG-1625 sensor continuously monitors for the specific acoustic frequencies associated with breaking glass. When these frequencies are detected, the sensor triggers an alarm condition on the connected security system.
- Fonctionnement normal : The sensor remains in a standby state, monitoring its environment.
- État d'alarme : Upon detecting glass breakage, the sensor's relay changes state, signaling the alarm control panel.
- Indicateur LED : A built-in LED typically illuminates during detection or test mode to provide visual feedback. Refer to the sensor's internal documentation for specific LED behavior.
6. Entretien
The Honeywell Intellisense FG-1625 sensor requires minimal maintenance to ensure continued reliable operation.
- Nettoyage: Periodically wipe the sensor's exterior with a soft, dry cloth to remove dust. Do not use abrasive cleaners or solvents.
- Essai: It is recommended to test the sensor annually using a glassbreak simulator to confirm its detection capabilities. Follow the instructions provided with your simulator.
- Contrôles environnementaux : Ensure the sensor's environment remains free from excessive vibrations, loud noises (unrelated to glass breakage), or obstructions that could interfere with its acoustic detection.
7. Dépannage
If the sensor is not functioning as expected, refer to the following common issues and solutions:
| Problème | Cause possible | Solution |
|---|---|---|
| Sensor does not respond to glass breakage. |
