Abstract
A circuit for controlling operation of a load, such as an alarm circuit in a fire protection system, in which operation of the load is delayed for an adjustable time period. The load control circuit includes a DIAC for generating a first trigger signal, an SCR which generates a second trigger signal, and a switch, preferably a TRIAC, which provides a supply voltage to the load upon receipt of the second trigger signal. A variable resistor is provided to adjust the time required to generate the first trigger signal.
