C. Installation
Introduction
These instructions cover installation procedures for
the BBU. Refer to Figure 500.6 for the location of the
input socket. The input socket of the key system
must be a female Mate-N-Lok type connector.
Installation Checklist
Remove the BBU cover by turning the 4 screw
locks and lifting the cover.
Install the two 12 V DC batteries in the battery
compartment. Thread the plastic tie wrap
through the vent holes in the side of the battery
compartment and fasten around both batteries.
Cinch the tie wrap tight.
The following items are required to install the BBU:
l
1 BBU with wire kit (5 wires) and tie wrap
l
4 No. 12 panhead screws (if wall mounted)
l
Screwdriver
Connect one of the adapter wires to the black
10” jumper wire. Now install this jumper wire
assembly between the NEG (-) terminal of bat-
tery 1 and the POS (+) terminal of battery ‘2.
Connect another adapter wire to the BBU red
battery wire. Now connect this wire to the POS
(+) terminal of battery 1.
l
Backboard or wall shelf if applicable
Mounting
The BBU must be located within 6’ of an AC recep-
tacle and 2’ of the KSU.
The BBU can be placed on a wall shelf or it can be
wall mounted.
Connect the BBU black battery wire to the NEG
(-) terminal of Battery 2.
Make sure the key system being connected is
turned on. Then connect the BBU DC output
cable to the battery input of the key system
KSU.

The BBU is designed to be mounted on a
backboard, either the backboard the KSU is
mounted on or one specifically for the BBU.
Mark for screw placement, either by measuring
(the 2 top keyhole mounting slots are 8 3/4” on
center) or by placing the BBU against the back-
board (before installing batteries) and marking
the location of the 2 slots.
Partially insert 2 No. 12 panhead sheet metal
screws into the backboard.
Suspend the BBU on these 2 screws. The large
section of the keyhole will allow the unit to easily
pass over the screwhead.
Slowly lower the BBU so the small section of
the keyhole is directly behind the screwhead.
Tighten each screw so the unit fits snugly
against the backboard.
Insert 2 more screws into the bottom of the BBU
where 2 more keyhole mounting slots are lo-
cated.
Before connecting the batteries, ensure the
BBU is unplugged from the AC outlet and
the ON/OFF switch on the BBU is turned off.
Grounding
To ensure that the BBU will operate properly, a good
earth ground is recommended. A metallic COLD
water pipe will usually provide a reliable ground path.
Carefully check that the pipe does not contain insu-
lated joints that could isolate the ground. In the
absence of the cold water pipe, a ground rod or other
source may be used. A No. 8 AWG copper wire
should be used between the ground source and the
BBU. A ground lug is provided on the lower-left side
of the BBU.
The ground wire should be kept as short as possible
and can be connected to the ground lug located on
the bottom of the 616 KSU. Installation of the BBU
is now complete.
D. General Information
There is a “power on” LED which is lit when the
supply is connected to the AC power source. There
is also a “battery” LED which is lit when the battery
back up is in use. The BBU is a filtered battery back
up power supply. Both input and output are fuse
protected. The charger circuit is floating with respect
to ground. The charging circuit provides a constant
voltage and is current limited to 350 milli-amps to the
2 gel cells.
