TYPICAL WIRING CONFIGURATION
Several ceiling pulls may be connected in parallel on one zone.
Calls made from ceiling pulls can be reset at:-
• A call point connected in parallel to the ceiling pull
• A reset point connected in parallel to the ceiling pull
• An NC941, NC942 or NC944 call controller
• Any standard indicator panel with its reset button fitted.
Note: Resetting calls at indicator panels is not recommended on nursecall
systems as there is a definite requirement for calls to be reset at source.
