15	Central Station Tips
15.1	Back-up Receiver
	Spare circuit boards and receivers should be available at the central station. Keep a spare kit
	on hand. UL Listed central stations monitoring burglary or fire alarms must have a spare
	receiver available for activation within 30 sec.

i	Notice!
	Keep spare cards for all receiver components.

	central station, you might prefer to use beehive lights instead of ringers.
	Rotary Lines
i	Notice!
	Use rotary receiver lines (hunt groups) to prevent delay in alarm signals during periods of
	busy central station traffic

Rotary lines are also important for providing alternate paths when a line is out of service. To use this feature have your dispatcher dial the out-of-service line and leave the calling telephone off the hook. This creates a busy signal on the line to all incoming communicators. The communicators automatically switch to an unused line. The telephone company provides rotary service when ordered.

i	Notice!
	UL and Factory Mutual central station service standards require constant monitoring of tele-
	phone lines.
