- 8 - AL842ULADA
Optional hookups:
1- Battery and AC monitoring: AC or Battery Fail condition will cause the common trouble input [C “FAULT” NC] to
report back to the FACP via input 1 and input 2. The common trouble input may also be used for other optional
supervisory monitoring.
To report AC and Battery Trouble connect the battery and AC Fail relay output shown in (Fig. 2a) to the
common trouble input.
2- Dry contact input (C “DRY1” NC) (C “DRY2” NC) can be used to alarm output from an
addressable module (these inputs are unidirection and cannot report back to trigger module).
Connection to triggering devices must be made within 20ft of distance and using conduit for wiring.
3- Auxiliary output (-AUX+) 24VDC at 1 amp max.
4- AC Local [NC, C, NO] should connect to the host control panel for local annunciation of
the trouble condition.
Note: If common trouble input, terminals marked [C “FAULT” NC] are not used, these terminals must be
shorted (connect jumper) to remain inactive. For optional hookups (Fig. 2b).
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level
(26.2-26.4VDC recommended range).
Battery Test: Under normal load conditions check that the battery is fully charged. Check specified voltage
both at the battery terminal and at the board terminals marked [+ BAT -- ] to ensure that there is no break in the battery
connection wires.
Fuses: Check input and output fuses on the power supply board, replace if necessary. Input fuse rating is
10 amp @ 250V, Output fuse rating is 15 amp @ 32V.
Note: Maximum charging current is 3.2 amp.
Note: Expected battery life is 5 years; however, it is recommended changing batteries in 4 years or less if needed.
