4.3.4 Notification Circuit Installation
Notification appliances used with the SK-6324 must be UL listed for compatibility with the
SK-6324. Refer to the list in the Appendix at the end of this manual for a list of compatible
devices.
For proper operation, you must use polarized notification devices with a model 7628 4.7k
ohm end-of-line (EOL) resistor on each loop. Select ANSI output pattern, if desired. Output is
configured as steady (continuous sound) at the factory. See Section 5 for information on
changing the pattern.

4.4 Alarm and Trouble Relays
The SK-6324 has built-in relays for alarm and trouble. The alarm relay is energized during
any alarm condition. The trouble relay is energized during any trouble or supervisory trouble
condition. Each relay has three terminals (N.O., Common, and N.C.). Refer to Figure 3-1 for
location of these terminals.
4.5 Auxiliary Power Circuit
The SK-6324 has a power limited auxiliary power circuit which can source up to .5A. The
terminal is labeled “AUX PWR”. Refer to Figure 3-1 for location of this terminal.
