ASCO Controller 8214G, 8215G, 8215B Dimensions Sample Parameter Selection Manual

Features,

ASCO's reputation and long-term control experience guarantee a highly reliable system with full ASCO coordination. ?If the control voltage is completely lost, or drops to approximately 50% of the normal value, the relay de-energizes and closes normally with a valve to cut off the gas flow. ?The valve will not open when voltage is restored unless an authorized person operates the key switch on the console. This eliminates the risk of gas leaking unknowingly. The gas may also be turned off by pressing the normally off button located on the console. ?For convenience, auxiliary buttons such as ASCO catalog numbers 173A19 and 173A20 can be located at various accessible points throughout the building. ?No need to use the annoying hum of DC control provided by the relay panel. ?Shallow depth NEMA Type 1 flush mount enclosure allows for direct wall mounting, conveniently eliminating obstructions in hallways or high traffic areas. ?ASCO dustproof industrial relays and solid state rectifiers are designed to provide long life. ?The terminal and installation diagram positions are clearly marked on the inside door. ?Approved for use in public schools by the New York City Board of Education.
