Keypad Jumper Options
Keypad Numbering (ident)
All keypads must have the ident jumper in position in order that the system can
recognise the keypad it is communicating with. This information is written to the log as
the system is set and unset. If greater than four RKPs are required on the
872
the Multi
Keypad option should be programmed to On, two keypads may then share the same
ident. It should be noted that LCD & LED RKPs may not share the same ident.
LCD and LED versions
Four jumper links are fitted on the LCD and LED versions of the keypad. On earlier
Standard keypads the legend was slightly different as shown in Fig 12.

Note:
Contour keypads fitted with ACE have two additional jumpers for the ACE
functions, these are:-
US
This jumper is the user select. With the jumper link removed each
ACE key fob will occupy one user code from the system, this is
termed as high security mode.
With the jumper link in position the ACE will occupy one user code
from the system but up to 28 key fobs may be programmed
into the ACE, this is normal security mode.
NVM
With this jumper in position the ACE NVM contents will be cleared
when the unit is powered up. All codes will be lost
On first power up this jumper should be on and then removed after.
The ident jumper should be positioned across the pins in one of the positions
before
the system is powered up.
