Section 5 Commissioning System
5.5 Installing Manual Valve Actuator
Attaching the manual valve actuator to the electric valve actuator when the actuation pin is not fully locked into
the “up” position may cause the cylinder valve to actuate, resulting in potential injury and/or property damage.
Reset the manual valve actuator by pulling up on the palm button and inserting the ring pin. e actuation
pin should be in the full up position before installing on the electric valve actuator. If the pin is not reset the
valve could open when the manual valve actuator is threaded onto the electric valve actuator.
e manual valve actuator assembly has a swivel base that is threaded onto the top of the electric valve
actuator.
e actuator is to be installed hand tight until contact is made between the manual valve actuator and
the top of the electric valve actuator. A small gap may be present between the bottom of the manual valve
actuator and the top of the electric valve actuator.
The system is now fully armed and commissioned. Actuation of the manual or electric valve actuators will result
in the discharge of the system.
5.6 Warning Signs
Warning signs must be placed at entrances to and inside protected areas.
5.7 Additional Considerations
Janus Fire Systems® equipment as shipped does not require painting.
5.8 Enclosure Venting Considerations
e eectiveness of a total ooding re extinguishing system depends, in part, on retention of the agent
mixture within the protected volume for a period of time. Retention of the agent within the enclosure
requires that leakage be minimized, however, addition of a gaseous re extinguishing agent to an enclosure
having limited vent area will naturally result in a change of pressure therein. If the enclosure is sealed too
tightly during the agent discharge, i.e., too little vent area or equivalent leakage area (EQL), the pressure
change could exceed the structural strength of the enclosure. Conversely, if the enclosure has too much
vent area then FM-200® leakage will occur rapidly, leading to short retention time of the agent within
the protected volume. us, the use of gaseous re extinguishing systems must address both pressure relief
within the protected volume during the period of agent discharge, and retention of the agent-air mixture
within the enclosure for a specied period of time after the completion of the discharge.
