Lock Out Tool 12738

The Amerex 12738 Lock-Out Tool (also known as the Setup/Lock-Out Tool) is designed for use with Amerex Kitchen Protection Systems using MRM (Manual Release Module) and PRM (Pneumatic Release Module) release modules. The tool prevents accidental system discharge while installing or servicing the system — it stabilizes the manual-pull cam housing and secures the link plate tension during setup and maintenance procedures, allowing the technician to work on the release module and detection cable network safely without risking an unintended discharge.

Accidental discharge during Amerex KP system installation or service is a serious safety and liability risk — it wastes the wet chemical agent charge, requires complete system cleanup and recharge before the kitchen can reopen, and can injure nearby workers if the discharge occurs unexpectedly. The 12738 lock-out tool eliminates this risk by mechanically securing the release module in the locked-out position throughout the service procedure. This makes it an essential fire suppression tool for every Amerex KP system installer and service technician — analogous in purpose to the SRMKPIN keeper pin for Buckeye systems or the keeper pins used across other kitchen fire suppression system brands.

The 12738 is listed in the amerex fire suppression system parts documentation as the OEM lock-out tool for Amerex KP MRM and PRM release modules. Available through authorized amerex distributors. The Amerex KP system installation manual specifies when and how to install and remove the 12738 during each phase of system installation, cable tensioning, and commissioning. Always remove the lock-out tool and verify the release module is fully armed before leaving the site at the end of any service visit — a system left with the lock-out tool installed cannot activate automatically or manually, and is effectively out of service.

Installation and Service Use

Install the 12738 lock-out tool per the Amerex KP system installation manual at the start of any service procedure involving the MRM or PRM release module or the detection cable network. The tool stabilizes the cam housing and secures the link plate to prevent the release module from firing during cable tensioning, nozzle adjustment, or module inspection. Follow the Amerex KP manual sequence for installing and removing the tool at each step of the installation or service procedure.

Critical — Remove Before Leaving Site

The 12738 lock-out tool must be removed and the system returned to fully armed status before the technician leaves the site. A system with the lock-out tool installed is not capable of automatic or manual activation — it provides zero fire protection while the tool is in place. Verify the tool has been removed, the release module is armed, the gas valve is reset, and all other system components are in service-ready condition before sign-off. Document the service event in the fire suppression system inspection record.

Is the 12738 compatible with both MRM and PRM Amerex release modules?

Yes. The 12738 is designed for use with both the MRM (Manual Release Module) and PRM (Pneumatic Release Module) configurations in the Amerex KP Kitchen Protection system. Verify the correct lock-out procedure for each module type in the Amerex KP installation manual — the tool installation sequence may differ slightly between MRM and PRM configurations.

What happens if the lock-out tool is left installed when the kitchen reopens?

A kitchen fire suppression system with the 12738 lock-out tool installed cannot respond to a fire — neither automatically via the thermal detection line nor manually via the pull station. This is a critical life-safety and code violation. The system must be considered impaired and the kitchen should not be in operation until the tool is removed and the system is returned to armed status. Always conduct a final armed-status verification before leaving any Amerex KP service site.
