AL642ULADA - 5 -
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.
Amount of Notification Appliances per NAC:
Amseco 27 per NAC* System Sensor® 32 per NAC*
Faraday 39 per NAC* CooperWheelock® 32 per NAC*
Gentex® 32 per NAC*
*Not to exceed a maximum of 2.5 amp per NAC.
Terminal Identification Table:
AL842LGK - Logic Board
Terminal Legend Function/Description
IN1+, IN1-
IN2+, IN2-
(Supervised)
These terminals connect to the 24VDC FACP notification appliance circuit outputs. (Class A,
Style Z or Class B, Style W, X, Y) Input trigger voltage is 8-33VDC @ 5mA min. Terminal
polarity is shown in alarm condition. During an alarm condition these inputs will cause
the selected outputs chosen to drive notification appliances. The designated outputs are set by
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.
RET1+, RET1-
RET2+, RET2-
(Supervised)
For Class A, Style Z hookups these terminal pairs return to FACP NAC1 and/or NAC2.
For Class B, Style W, X, Y hookups the FACP EOL resistor from the NAC1 and/or NAC2
outputs are terminated at these terminals. Optionally, other notification appliances or additional
signaling circuit power supplies may be connected to these terminals. If this option is chosen the
EOLresistor must be terminated at the last device.
C “DRY1” NC C
“DRY2” NC
(Dry input trigger)
An open across these inputs, will cause the selected outputs chosen to drive notification appli-
ances. The designated outputs are set by output switches [OUT1 through OUT4] (Output
Programming Selection Table, pg. 4). Note these inputs are unidirectional and will not report a
trouble conditionto the FACP.

(Supervised)
Notification appliances are connected to these regulated outputs (see Application Guide pg. 2-4).
Each power-limited output will supply 2.5 amp. Two (2) outputs may be connected in parallel for a
maximum NAC output capability of 4 amp. Total supply current is 8 amp (see note below). Outputs
are controlled by designated input 1 [IN1] or input 2 [IN2] (Output Programming Selection
Table, pg. 4). Maximum line loss or voltage drop (tested with 2.5V).

Used for Class A, Style Z hook-ups to terminate loops originating on
[OUT1], [OUT2], [OUT3], and [OUT4] respectively.
C “FAULT” NC
(Common
trouble input)
An open circuit across this pair of terminals will cause [INP1 and INP2] LEDs to
simultaneously signal a trouble condition back to the FACP (Typically used to report
AC or BAT Fail). (Fig. 2e, pg. 7).
NC, C, NO
(Common
trouble output)
These are dry contact trouble outputs that report any general loop/system trouble conditions.
(Typically used to trigger a digital communicator or other reporting devices).
(form “C” contact 1 amp / 28VDC 0.35 Power Factor) (Fig. 2, pg. 7).
-- AUX+
This separate 1 amp max. auxiliary Special Application Power output circuit is typically used
to power 4-wire smoke detectors. See attached list of devices (Appendix A, pgs. 10-12).
-- AUX2 +
This separate auxiliary regulated power output circuit supplies up to 1 amp during stand-by and
alarm condition. Since this output is not disconnected from its load during AC power failure use
the (Battery Calculation Worksheet, pg. 9) to determine battery size and/or allowable stand-by
and alarm current.
+ DC -- 24VDC from power supply.
