SIMPLEX 4901-9820 RED NON-ADDRESSABLE HORN, FREE SHIP SAME DAY 415 TrueAlert non-addressable horn model Simplex 4901-9820 is an audible notification appliance with a loud and penetrating, harmonically rich sound that can be controlled either directly from a standard NAC (freerun operation mode) or by the SmartSync two-wire operation mode. In the free-run mode, a positive voltage from the controlling NAC will activate the horn according to the desired output of continuous or coded output per the controlling NACs capabilities. When selected for SmartSync mode and used with compatible Simplex control; this horn can be wire onto the same two-wire NAC circuit as visible appliances but with separately controlled operation. Typical applications are audible notification activate as onuntil-silenced and visible notification appliances activated on-untilreset. In addition, visible appliances (strobes) on the same circuit are activate with synchronized flashes. Allowing these separate controls to be carry on the same two-wire NAC circuit can significantly reduce installation time and expense for both retrofit and new construction.
