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.
(see Power Board Parameter for use of AC Delay, pg. 6)
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 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. 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 fuse on the power supply board, replace if necessary.
Input fuse rating is 5A @ 250V.
Note:
Maximum charging current is 650mA.
Note:
Expected battery life is 5 years; however, it is recommended changing batteries in
4 years or less if needed.
