Compass Intelligent Input Module
A device that provides information to a panel so it can make event or alarm decisions.
- Input Supervision
Detects if someone has tried to tamper with sensors/locks. These attempts can be detected by sensing multiple voltage levels at the door position switch. Inputs can be configured in up to 4 states. 2 state devices are like a light switch. On or off. 3 State devices with a resistor in series can determine whether an input is active, inactive, or not short circuited. 3 state devices with a resistor in parallel can determine whether an input is active, inactive, or the circuit is not open. 4 state devices have both parallel and series resistors and determine whether an input is active, inactive, and the wiring is open or shorted.
The initial surge of current through a load when power is first applied. Lamp loads, inductive motors, solenoids, and capacitive loads all have inrush or surge current. Resistive loads, such as heater elements, have no inrush.
A system of multiple doors with controlled interaction. Interlocks are also known as light- traps, air-traps, man-traps, and sally-ports (see security interlock).
