Figure 10: Wiring of key switch and alarm contact for input type 33
Input type 33 (24-hour alarm & isolate input) is used to wire a key switch and an
alarm contact to the same input. For example, a key switch used to isolate a
shop’s input in a shopping centre where only one input is available for each shop.
Alarm is generated when input changes from sealed to open or short.
• The normal state of the key switch is sealed
• When unsealed the input is isolated, no alarm generated
