1.1 Federal Communications Commission Interference Statement
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. To assure continued
compliance, use only shielded interface cables when connecting to
computer or peripheral devices. Any change or modification not
expressly approved by the party responsible for compliance could
void the user's authority to operate this equipment.
1.2 General Description
The DC UPS (DC Power Supply /Battery Back-Up Unit) is designed
to be mounted inside a customer premise. The DC UPS converts
90-264 Vac to 12Vdc and provides four to eight hours of backup
battery power for lifeline equipment service.
Alarm outputs are available on the DC UPS to monitor the status of
the backup battery (On/Low/Faulty/Missing). The DC UPS indicates
its status to the resident with LEDs and to the equipment by a signal
return connection.
1.3 Components
The DC UPS consists of an integrated AC to DC power supply and
battery backup unit.
The DC UPS houses a dedicated battery charger to maintain a 12V,
7AH (or 7.2Ah) lead-acid sealed battery, battery monitoring and
alarm circuitry. User interface for the dedicated power supply
consists of a single LED to indicate correct DC output.
The DC UPS contains four indicator LEDs to provide operational
status at a glance, status audible alarm and two customer operation
buttons that one to make the unit enter the Cold Start mode when
user replace the battery and the other to Enable/Disable audible
alarm.

ONLY qualified personnel should service this equipment.
SAVE THESE INSTRUCTIONS - This manual contains important
instructions for our inverter that should be followed during installation
and maintenance.
Verify line voltage requirements and the supplied line voltage prior to
installation.
Verify branch circuit breaker or fuse on the service feed is correct for
the equipment being installed.
The battery contains hazardous currents and may present a burn
hazard if damaged or shorted.
The following precautions should be observed when working on the
unit:
1. Remove watches, rings, or other metal objects.

2. Wear protective clothing and eye protection when working with batteries and installing this equipment.
3. Always carry a water supply to wash eyes and/or skin if exposed to battery electrolyte.
4. Use tools with insulated handles.
5. Examine the packing container for damage. Notify the carrier immediately if damage is present.
6. Do not disassemble the unit.
7. Do not operate near water or excessive humidity.
8. Keep liquid and foreign objects from getting inside the unit.
9. Do not operate close to gas or fire.
10. Do not operate if the unit is leaking liquid or if any liquid residue is present.
11. Auxiliary power source needs to use Alkaline battery (1.5V*12pcs)
Electrical Warnings
Servicing this equipment may require working with protective covers removed and utility power connected. Use
extreme caution during these procedures.
Check that the power cord(s), plug(s), and output terminal are in good condition.
No user serviceable components other then the battery are present in the DC UPS.
Battery Warnings
Danger of explosion if battery is incorrectly connected or replaced. Use only approved replacement batteries.
Worn-out or damaged batteries are considered environmentally unsafe. Always recycle used batteries or
dispose of the batteries in accordance with all federal, state and local regulations.
Any gel or liquid emission from a valve-regulated lead-acid (VRLA) battery contains sulfuric acid, which is
harmful to the skin and eyes. Emissions are electrically conductive and corrosive.
Batteries produce explosive gases. Keep all open flames and sparks away from batteries.
Batteries contain or emit chemicals known to the State of California to cause cancer and birth defects or other
reproductive harm. Battery post terminals and related accessories contain lead and lead compounds. Wash
hands after handling (California Proposition 65).
Wear protective clothing and eye protection whenever installing, maintaining, servicing, or replacing batteries.
If any battery emission contacts the skin immediately and thoroughly wash with water. Follow approved chemi-
cal exposure procedures.
Neutralize any spilled battery emission with the special solution contained in an approved spill kit or with a
solution of one pound Bicarbonate of soda to one gallon of water. Report chemical spills and seek medical
attention if necessary.
Always replace batteries with new batteries of an identical type and rating.
Never use non-insulated tools or other conductive materials when installing, maintaining, servicing or replacing
batteries.
A battery showing signs of cracking, leaking, or swelling should be replaced immediately with a battery of
identical type and rating.

Prior to Installation
Installation of the unit must be performed by skilled technicians and electricians familiar with electrical equipment.
Do not allow unqualified personnel to handle, install, or operate the equipment.
Locate a location for the DC UPS within 6 feet or 8 feet power cord of an existing AC receptacle.
Different countries have different types of power cords as shown in the specifications.
Mechanical Installation
Install this unit in a sheltered location away from direct contact with water and rain.
Mounting Orientation
Locate a stud within the wall the unit is mounted and screw 2, #10-24 pan head screws 2.5" apart into the stud,
leaving ½" of the shaft of the screw exposed below the screw head. Mount the unit onto the screws and tighten the
screw firmly to prevent the unit from sliding after mounting. Ensure that the door has sufficient space to open.
1. Unit must be installed with battery removed.
2. Place the unit against the wall, and using the keyholes (located on rear of
enclosure) as a template, drill pilot holes for two 10-24 pan head screws.
3. Insert screws into each hole, leaving approximately 1/2" of screw protruding from
wall. Align keyholes with screws, and slide unit into place. Tighten screws firmly.
4. Connect battery wires. Verify that red wire is connected to positive terminal, and
black wire is connected to negative terminal. Unit will power up.
5. Carefully insert battery into unit. Do not pinch battery wires. Close front panel.
6. Install AC power cord.
Power Wiring Notes
The DC UPS has no electrically conductive parts exposed to the user.
Alarm Connection
To access the craftsperson interface a standard 216 tool is required.
3.5.1 Alarm Connections
Alarm connections are made using the supplied insulation displacement connector (IDC).
1. Verify DC UPS is disconnected from AC power.
2. Connect the 5-wire cable to the IDC in Figure
3. The connector pins are labeled with their function. Refer to the
specific instructions from the equipment supplier to determine what
alarms are accepted from the DC UPS to the equipment.
Alarm Conditions/Action (see table1)
AC Wiring Connection
The Power Supply will come with a separate power
cord. The AC plug must be plugged into a grounded
3-wire style of AC receptacle for proper equipment
operation.
