Some are listed on the previous page.2 Connect 4-wire smoke detectors across points 1 through 8 (25 through 38). See Figure 4-2.3 If EOL resistors are presently connected across the terminals, remove them.4 Connect the EOL power supervision relay module (435243) and the 2k EOL resistor at thelast detector on each point. See Figure 4-2.Note: Each point must have its own power supervision relay module.5 Connect the power wires from the 4-wire smoke detectors and the EOL power supervisionrelay module to the control unit. Connect the ground wire to terminal 12, and the positivepower to the normally closed side of the auxiliary relay (terminal 9). See Figure 4-2.Note: Auxiliary power is not automatically reset after an alarm, and therefore must bemomentarily interrupted using the built-in auxiliary relay.6 Move jumper P3 to short pins 1 and 2, making the auxiliary relay wet (12-volt output).7 Program the Auxiliary Relay Output to 4-wire smoke detector reset.Points 3 and 4 Style "D" (Class A Fire Loop) ConfigurationThe style "D" configuration is a Class A Fire Loop. It can annunciate an alarm condition even with anopen in the wire run. A break or open in the wire run will annunciate a trouble condition on point 3,but the system can still annunciate an alarm condition, if a sensor is shorted.Wiring for Style "D" Configuration2kEOLRPOINT 432313029POINT 3+--+CONTROLPANELA BCBreak #2Break #1Figure 4-3: Style "D" Configuration on Points 3 and 4
