low Switch Information for Emergency Shower and Emergency Eyewash Units How does a flow switch work in an alarm? A flow switch operates when it senses water flow. This is achieved by a paddle that is inserted into the waterway. When an emergency shower or emergency eyewash is activated the paddle moves and closes a switch thus activating the alarm. What is the difference between a stay-open and self-closing valve? The ANSI Z358.1-1998 standard for emergency showers and emergency eyewash units recommends that the activating devices for emergency showers and emergency eyewashes remain open once they are activated. To achieve this Speakman Company uses ball valves which require specific actions to open and close the valve permitting the emergency eyewash or emergency shower to be used hands free after activation. A self closing valve is a spring activated device that requires a specific action to activate but will close on its own. This type of device requires the user to hold an activating lever while the unit is in operation and does afford hands free operation as required by the ANSI standard. In some school applications self-closing valves are permissible provided that approval is received from the local code authorities. In these situations this is desirable to prevent accidental or mischievous activation of an emergency shower which could cause significant water damage. |
