Fire detection systems
should be able to specify which detector bases should be used with different detector brands. A manual call-point consists of a simple switch with a resistor in series with it, usually 470 Ohms or 680 Ohms. When the call point is activated, the resistor is switched across the line, and a current of 50-80mA, dependant on the control panel, is drawn.
