Chapter 6: Maintenance
38 ReadySET Aspirating Smoke Detection System Installers Handbook
Introduction
This chapter contains maintenance instructions for the ReadySET aspirating smoke
detection system. These procedures should be performed on a scheduled basis. In the
event that system problems are found during routine maintenance, refer to
“Troubleshooting” on page 34. Failure to properly maintain the system may affect the
functioning of the system.
Scheduled maintenance
The scheduled maintenance of the system should be performed at an established
interval. At a minimum, the interval between performance of maintenance procedures
should not exceed any applicable regulations. (See NFPA-72 or other local
requirements.) This chapter contains minimum maintenance procedures, however,
additional and/or more frequent procedures may be required by applicable codes and
standards.
Maintenance procedures
The following paragraphs outline general scheduled maintenance procedures.
Visual check
The visual check must be performed at least every six months. This check is to
ensure pipe network integrity. Ensure that the design is still valid. Building upgrades
can require changes to the piping and detector requirements.
To perform the visual check, observe the entire piping network and check for
abnormalities in the pipes including any breaks, blockages, crimps, etc.
Battery status check
Caution: Any battery that has been in service for 36 months or more must be
replaced.
The battery backup used in the power supply to power the detector must be tested
at least every six months.
A battery status check is best accomplished by running the load with the batteries
for about one hour. While the load is still on, measure the individual battery voltages.
If any battery reads 1.5 V or more below its rated voltage, that battery should be
replaced.
