OPERATION
Master Power Switch
This switch allows users to turn On or Off all power from the DC Output terminals for servicing.
Battery Supervision
If DC power from the ELK-P1417 is lost (i.e. AC power outage), the battery should continue to supply power to the ELK-P1215CB DC Output
terminals. The battery's voltage is then monitored and if the voltage drops to 11 volts, then the –SUP low battery supervision output will turn ON
(pull to ground) indicating a Low Battery condition.
The -SUP output can be connected to an LED, 12 Volts DC Sounder, or a zone on a Security Control to report a low battery condition
.
Note: The –SUP output will only work until Low Battery Cutoff activates, (see below) at which time -SUP becomes inactive since all power to the
P1215CB board will be completely shutoff.
Low Battery Cutoff
If DC power from the ELK-P1417 continues to be lost for an extended period, the battery should continue to supply power to the ELK-P1215CB
DC Output terminals. The battery's voltage is monitored during this time and if the voltage drops to 9 volts, then the battery will be Cutoff
(disconnected) from the DC Output terminals. This helps to prevent “deep discharging” of the battery.
Hookup
1. Observe
correct polarity
on all connections.
2. The ELK-P1215CB circuit board can be mounted directly on top of a battery. (ELK-P1215K kit includes battery, sold separately for ELK-P1215 kit)
3. Connect the two battery wires to the battery terminals. Red wire to positive, Black wire to negative.
4. Connect ONLY the ELK-P1417 Power Pack to the DC Input terminals. DO NOT CONNECT an AC TRANSFORMER.
Two-conductor jacketed cable having Red and Black color coded wires are recommended, minimum 18 AWG. Maintain polarity if using
non-color coded Zip cord. The consequences of using too small of a wire gauge, or extending the wire length beyond the recommended
lengths may harm the ability to properly charge the battery, especially at full DC Output Load.
If using 18AWG - Do NOT exceed a distance of 10 feet.
If using 16AWG - Do NOT exceed a distance of 15 feet.
If using 14AWG - Do NOT exceed a distance of 25 feet.
5. Plug the ELK-P1417 into a constant 120VAC source.
6. Connect the DC Output to the desired load.
7. Turn on Master Power Switch.
