APPENDIX B: MAINTENANCE AND REPAIR
IMPORTANT!
The XT+ maintenance and repair must be performed by qualified service personnel.
XT+ units do not require any specific maintenance but should be kept clean by wiping with a slightly damp cloth.
Ensure that water does not enter the enclosure. Testing of the extinguishant system should only be carried out
by trained personnel and must be done with appropriate isolation measures in place to ensure that accidental
discharge of the extinguishant agent is avoided. The electronic assembly and front plate can be replaced if
necessary. AC and battery power should be removed before any internal components are replaced.
Batteries
Load test the batteries and inspect their connections to the power supply as part of annual system maintenance.
WARNING!
Battery terminals and leads are not power-limited. Shorts can cause a fire or an explosion. Use
extreme caution while connecting standby batteries.
Replacing Battery Leads
When replacing leads, disconnect them from the battery before disconnecting them from the power supply.
Replacing Standby Batteries
Typical battery life is 5 years. Specify replacement batteries that are Valve Regulated Lead Acid (VRLA) types.
