The timer responds to the control signal by producing a fixed duration operation signal which is applied to a switching system within the power coupling to the lamp array. A pair of alternative power coupling networks are utilized to alternatively operate the lamps at either of two different voltages in response to the control circuit and switching system. Audible and visual indicating alarms are utilized to alert the operator to the operating state of the system. | |
