VP-6124-UPS

ADD ON OPTION FOR THE VP-6124/VP-6124-E
POWER SUPPLY

INTRODUCTION

The VP-6124-UPS is an optional unit that allows the
VP-6124/VP-6124-E to supply power during a power
outage.

The VP-6124-UPS is comprised of a VP-6124-UPS
(Charger) and a VBB-1424 (Battery Enclosure). The
VP-6124-UPS connects to the VP-6124 Power Supply
(To receive power to charge the batteries).

Listed below are specifications and recommendations
for power sources as well as precautionary
instructions.

UPS Float Standby Charging

Charging Voltage: 27.6 Volts (13.8 Volts per battery)
Current Limit: 900mA charging
100mA at 27 Volts final charge
Fusing: 1 Amp auto-reset polyswitch
6 Amps accidental reverse battery polyswitch

Time Required to Recharge Battery

7AH Battery: 14 hours

Length of Time Battery Will Provide
Power

• With four 7AH 12V batteries for 14AH total
3 Amps load draw: 3 hours run time
6 Amps full load: 1.5 hours run time
Use of batteries greater than 7AH is not
recommended since 90% of all power outages are less
than an hour in length and the time to evacuate a
building is less than an hour.

NOTE: To insure trouble-free UPS back-up
operation, five years batteries must be replaced five
years from the date of manufacturing.

DIMENSION S/WEIGHT

• 10.30"H x 3.50"W x 2.25"D

INSTALLATION

The VP-6124-UPS (Charger) is designed for wall
mounting only. Screw the mounting plate to the wall

near the VP-6124/VP-6124-E and position the
VP-6124-UPS onto the mounting plate.

Attach the UPS unit securely to the bracket lip using
the 6-32 x 3/8" long Phillips head self-tapping screw
supplied. Place the VBB-1424 on the floor within six
feet of the unit.

CONNECTIONS

• Disconnect AC power from the power supply.

• Remove plug button from the VP-6124/VP-6124-E.

• Remove wire access cover from the

VP-6124/VP-6124-E.

• Using the cable designated by the tag labeled

Valcom P/N WA-784 with four positions
connector and attached to VP-6124-UPS
(Charger), place the Molex connector through the
hole on the power supply and connect the
charger to the Molex input connector on the
VP-6124 Power Supply.

• Snap strain relief into place.

• Replace wire access cover on the

VP-6124/VP-6124-E.

• Remove cover from Battery Backup.

• Push cable labeled Valcom P/N WA-783 with two

positions connector through the hole on the
battery enclosure and snap strain relief into
place.

• Attach connector from VP-6124-UPS to battery

box.

• Replace access cover.

• Plug power cord from VP-6124/VP-6124-E into AC

outlet.

• Turn ON circuit breaker on Battery Backup.

OPERATION

When a power failure occurs, the charger beeps to
alert personnel that the supply is operating on the
batteries and there is 1.5 hour run time available at 6
Amps full load. Pressing the white button will mute
the beeping.

There are three (3) LEDs located on the charger.
When the charger is connected to the
VP-6124/VP-6124-E power supply, the green LED
illuminates signifying the power supply and charger
are on line and the batteries are charging.

If the red LED illuminates, this denotes that the
batteries have dropped below 20 Volts and the UPS
goes into low voltage shutdown to protect the
batteries from damage. This disconnects the load.
The red LED will turn off and batteries reconnect
when power returns and the batteries are charged
above 25 Volts.

Pressing the battery test button illuminates the yellow
LED if the battery is above 24Volts (Signifies a good
battery). The charger will charge the batteries to 27.6
Volts in a 14 hour per iod assuming completely
discharged batteries.

Batteries must be replaced every five years.
CAUTION: To reduce the risk of fire or injury
to persons, read and follow these instructions.

1. Supplied with four (4) Union Type MX12070
batteries. Use only Union Type MX12070
batteries.

2. Do not dispose of the batteries in a fire. The cell
may explode. Check with local codes for possible
special disposal instructions.

3. Do not open or mutilate the batteries. Released
electrolyte is corrosive and may cause damage to
the eyes or skin. It may be toxic if swallowed.

4. Exercise care in handling batteries in order not to
short the battery with conducting materials such
as rings, bracelets, and keys. The battery or
conductor may overheat and cause burns.

5. Do not attempt to recharge the batteries provided
with this or identified for use with this product.

The batteries may leak corrosive electrolyte or
explode.

6. Do not attempt to rejuvenate the batteries
provided with or identified for use with this
product by heating them. Sudden release of the
battery electrolyte may occur causing burns or
irritation to eyes or skin.

7. When replacing batteries, all batteries should be
replaced at the same time. Mixing fresh and
discharged batteries could increase internal cell
pressure and rupture the discharged batteries
(Applies to products employing more than one
separately replaceable primary battery).

8. When inserting batteries into this product, the
proper polarity or direction must be observed.
Reverse insertion of batteries can cause charging,
and that may result in leakage or explosion
(Applies to products employing more than one
separately replaceable primary battery).

9. Remove the batteries from this product if the
product will not be used for a long period of time
(several months or more) since during this time the
battery could leak in the product.

10. Discard "dead" batteries as soon as possible since
"dead" batteries are more likely to leak in a
product.

11. Do not store this product, or the batteries provided
with or identified for use with this product, in
high-temperature areas. Batteries that are stored
in a freezer or refrigerator for the purpose of
extending shelf life should be protected from
condensation during storage and defrosting.
Batteries should be stabilized at room temperature
prior to use after cold storage.

NOTE: The batteries are excluded from the
WARRANTY.
