Remove the SK1L from the packing box and verify that all the contents are there:
SK1L Keypad
SK1L Installation Manual
SK1L Owner's Manual
2)
The front and rear covers snap together and can be easily separated for installation. Insert
a small screwdriver into the slots located at the bottom of the keypad and gently press in and
lift the front cover away from the backplate.
SURFACE MOUNTING
1)
Using the rear plastic housing cover as a template, mark the four mounting holes on the wall.
There are several different sets of mounting holes to suit a variety of different situations. The
recommended mounting height is between 48" and 54" from the floor to the top edge of the
keypad.
2)
Insert the keypad wire through the opening in the center of the back housing and then fasten
the back to the wall using sheet metal screws and wall anchors. On solid walls use the side
knock outs for wiring.
ELECTRICAL BOX MOUNTING
1)
The SK1L may be mounted directly onto a double gang box using the four curved slotted
holes and four #6 x 32 x 1" pan head screws.
2)

PROGRAMMING THE KEYPAD
The new version of the SK1L keypad has a 93C66 chip in location U1 on the back of the keypad
PCB. Original keypads have a 93C46 chip in location U1.
The SK1L keypad needs to have its keypad address and its text messages programmed.
These are set to default values at the factory. The SC800 / 1600 system will work fine with these
default values. If you are using partitioned mode in the SC800 / 1600 then you must set the
keypad address to match the partition to which it is assigned. Refer to the SC800 / 1600
installation manual for instructions on Partitioned mode. If you choose you can also modify
the text messages. Older SK1L keypads do not have programmable text messages and the
keypad address is the only programmable location.
