SRM
The SRM is used in conjunction with the STRIKE™ ECS and is for UL Certification only
and cannot be considered for or used in installations of KP/ZD systems in Canada.
Actuator Disassembly (See Figure 1):
1.
Using 1 1/8” wrench, remove empty Nitrogen Cartridge (P/N 12856) from bottom of SRM
Assembly.
2.
Remove (unscrew) spent Linear Actuator (P/N 24448) from top of SRM Assembly.
3.
Using a 1” wrench, remove hex Body (P/N 26780) from top of the SRM Assembly.
4.
Locate and discard the small brass disc which was displaced from the end of the Linear
Actuator upon actuation.
It is normally found on top of the hex Puncture Stem Cap.
Actuator Inspection (See Figure 1):
5.
Inspect the upper SRM assembly (Puncture Stem, Stem Cap & Spring) for any damage or
foreign debris.
If any damage has occurred to SRM, replace the SRM.
6.
Verify that the Puncture Stem Assembly is in working order by pressing the hex Puncture Stem
Cap down and observing full travel of the Puncture Stem (fully compressed spring).
Verify that
the spring returns the stem to the raised position.
7.
Inspect and clean the Gasket (P/N 07247) on the bottom of the SRM. Replace if damaged.
Actuator Reassembly (See Figure 1):
8.
Replace the hex Body (P/N 26780), Ensure the Body is fully bottomed against the SRM
block.
Snug gently using a 1” wrench. Do not overtighten. Install new Linear Actuator and
Nitrogen Cartridge as instructed in Chapter 4.
FACTORY SUPPLIED PLUG. REMOVE AND
