Note: The AL642ULADA will only synchronize horns, horn/strobes and strobes that contain synchronization capability.
Contact signal manufacturer for more detailed info (see Appendix A.4, pg. 12). The same synchronization mode must be
selected for all outputs.

Terminal Legend Function/Description
These terminals connect to the 24VDC FACP notification appliance circuit outputs. (Class A, Style

the selected outputs chosen to drive notification appliances. The designated outputs are set by
(Supervised)
output switches [OUT1 through OUT4] (Output Programming Selection Table, pg. 4). A trouble
condition on an output loop will cause the corresponding input to trip the FACP by opening the
FACP loop. An alarm condition will always override trouble to drive notification appliances.
For Class A, Style Z hookups these terminal pairs return to FACP NAC1 and/or NAC2.

circuit power supplies may be connected to these terminals. If this option is chosen the EOL
resistor must be terminated at the last device.
An open across these inputs, will cause the selected outputs chosen to drive notification appliances.
