AL1042ULADA / R1042ULADA Installation Guide
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. 8a, pg. 11
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 20 ft. of distance and using conduit for wiring.
3- Auxiliary output (– AUX +) 24VDC at 1A max.
4- AC Local [NC, NO, C] 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 see
Fig. 8b, pg. 11
.
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 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 6.3A @ 250V, Output fuse rating is 15A @ 32V.
Note:
Maximum charging current is 1.5A.
Note:
Expected battery life is 5 years; however, it is recommended changing batteries in
4 years or less if needed.
