TESTING AND MAINTENANCE
5-1 INTRODUCTION
The FenwalNET 8000-ML
TM
System must be inspected, tested and maintained in accordance with
the requirements of NFPA 72 (latest edition), or in accordance with the inspection, testing and
maintenance schedule mandated by the Authority Having Jurisdiction (AHJ).
Follow the required inspection, testing, and maintenance procedures for the associated extinguishing
system(s) as directed by the manufacturer and by the standards and codes that apply to those
systems.
5-2 SEMI-ANNUAL AND ANNUAL TESTING
Perform the following tests as part of each semi-annual or annual system inspection:
5-2.1 Lamp Test
Test the LEDs on the control unit's display by selecting “Lamp Test” from the system menu. Refer to
Figure 3-31 for menu stucture location. Replace the display's membrane if any LED fails to
illuminate.
5-2.2 Battery Test
Test the standby batteries by selecting “Battery Test” from the system menu. Refer to Figure 3-31 for
menu stucture location. Replace all batteries if either the charging voltage or current do not fall within
the specified ranges.
Replace batteries every three years, or more frequently as recommended by the battery manufacturer.
If Battery Monitoring Mode is enabled, the system software will emit an audible signal beginning one
month before the replacement due date of the standby batteries, based on the original install date.
WARNING
Do not attempt any testing or maintenance of the FenwalNET 8000-ML System until
you have:
• Isolated all onboard releasing outputs via the Isolate function.
• Ensured that all RRMs are connected to the control unit.
• Physically disconnected the wiring to initiator assemblies (if used) from the release-
circuit terminals, shorted the leads together, and wrapped the leads in insulating tape
• Physically disconnected all control heads (if used) from their associated agent-storage-
container discharge valves
• Physically disconnected the wiring to solenoid valves (if used) for pre-action/deluge
sprinkler systems
• Ensured that emergency operations controlled by this system such as facility power
shutoff are bypassed
• Notified personnel in the facility and at off-premises monitoring locations that
you are working on the system and that you will inform them when system
servicing has ended.
