1. Introducere
The Notifier ISO-X Alarm Fault Isolator Module is designed to protect fire alarm system Signaling Line Circuits (SLC) from wire-to-wire short circuits. This module ensures that a short circuit on the SLC loop does not disable the entire loop, allowing other devices on the loop to continue functioning normally. It is an essential component for maintaining system integrity and reliability in fire detection and alarm systems.
The ISO-X module is compatible with various Notifier fire alarm control panels, including NFS-3030, AM2020, AFP1010, NFS-640, AFP-400, AFP-300, AFP-200, AFP-100, and System 5000.

3. Configurare și instalare
Installation of the ISO-X module should only be performed by qualified personnel in accordance with all local and national electrical codes, and the manufacturer's specific installation instructions (document 156-3624 referenced on the module itself).
- Deconectare de la curent: Ensure all power to the fire alarm control panel and associated circuits is disconnected before beginning installation.
- Montare: Mount the ISO-X module in a suitable location, typically within an electrical enclosure or junction box, using the provided mounting holes. Ensure proper ventilation if required by local codes.
- Cablaj: Connect the Signaling Line Circuit (SLC) wires to the designated terminals on the module. The module supports two SLC loops (SLC1 and SLC2) with positive (+) and negative (-) terminals for each. Refer to the wiring diagram provided with the module and the fire alarm control panel for correct polarity and connection points. The module is designed for 4-wire applications.
- Verificare: After wiring, visually inspect all connections to ensure they are secure and correctly terminated.
- Restaurarea energiei: Restore power to the fire alarm control panel and verify proper operation of the SLC loop and connected devices.
Note: The module is designed for indoor, dry applications only.
4. Funcționare
The Notifier ISO-X module operates passively within the SLC loop. In the event of a wire-to-wire short circuit on the SLC loop, the ISO-X module automatically isolates the affected segment of the loop. This isolation prevents the short circuit from disrupting communication with other devices on the healthy segments of the loop.
Once the short circuit condition is cleared, the ISO-X module automatically restores the isolated segment to normal operation, allowing full communication across the entire SLC loop without manual intervention.
5. Întreținere
The Notifier ISO-X module requires minimal maintenance. Regular system inspections and testing, as mandated by local fire codes and standards (e.g., NFPA 72), will ensure the continued proper functioning of the module and the overall fire alarm system.
- Inspecție vizuală: Periodically inspect the module and its wiring for any signs of physical damage, corrosion, or loose connections.
- Testarea sistemului: During routine fire alarm system testing, verify that the fault isolation function operates correctly by simulating a short circuit (if permitted by system design and local codes, and only by qualified technicians).
- curatenie: Dacă este necesar, curățați ușor exteriorul modulului cu o lavetă uscată și moale. Nu utilizați substanțe de curățare abrazive sau solvenți.
6. Depanare
If a fault is indicated on the SLC loop, and the ISO-X module is suspected:
- Identify Fault Location: The fire alarm control panel should indicate the general location of the short circuit. The ISO-X module will isolate the segment containing the fault.
- Inspectați cablarea: Carefully inspect the wiring within the isolated segment for any signs of damage, pinched wires, or incorrect connections that could cause a short circuit.
- Verificați conexiunile: Ensure all terminal connections on the ISO-X module and connected devices are secure.
- Stare modul: Some ISO-X modules may have an indicator LED that changes status when a fault is detected. Consult the specific module's datasheet for LED behavior.
- Asistență profesională: If the fault cannot be identified and resolved, contact a qualified fire alarm technician for diagnosis and repair. Do not attempt to bypass or tamper with the module.
