TTP4: Keypad Shows SERVICE 9210
Initial Actions
• Refer to
TTP32 Silencing Alarms or Troubles, and
Clearing Keypad Memory
on page 70 to silence
alarms or troubles, clear keypad memory, and
view the points that are in alarm or trouble.
• Verify that the D9210B’s DIP switch address
corresponds with the appropriate access door.
Refer to
Table 10 on page 19.
• Verify that DIP Switches 5 and 6 on the D9210B
are in the ON position.
• Verify that the wiring between the control panel
and the D9210B is correct. Refer to
Figure 9 and
Figure 10 on page 19.
Procedure
This procedure uses [COMMAND][4][6] to show access door
status. In this example, Doors 1, 2, and 4 are all known good
access doors. Door 3 is the affected access door. The keypad
display shows “F” instead of “3” for Door 3.
UNLOCK: 1 2 F 4 - - - -
Refer to Table 11 on page 20 for display descriptions.
If you see an F, A, or D as described in Table 11,
continue with the TTP identified in Table 11.
Otherwise, continue with this TTP.
Locate the OPER MON LED on the D9210B. Refer to
Figure 11 on page 19.
Is the OPER MON LED flashing?
Refer to
TTP51 Device or Module Does Not Have
Power
on page 111.
Are there any other programmed access doors that
work as expected?

1. Remove all device wiring from the control panel’s
serial device interface (SDI) bus except for the
keypad used to view door status.
2. Connect the affected access door’s D9210B
directly to the control panel’s SDI bus, at the
control panel.
Removing all device wiring from the SDI bus
causes “F” to appear for all other programmed
access doors.
3. Go to a keypad assigned to the same area as the
affected access door. Press [COMMAND][4][6].
4. If using the D1255 keypad, when the keypad
displays CYCLE DOOR?, press [NEXT] once.
5. Using either a D1255 or D1260 keypads, select
UNLOCK DOOR?. The keypad then shows the
current status for all access doors programmed
into the system.
Does the keypad still display “F” for the affected
access door number?
Refer to
TTP47 Open Wiring on page 100 for
open wire issues. If this TTP does not solve
the problem, refer to
TTP48 Noise on Wire on
page
102.
Replace D9210B.
1. Go to a keypad assigned to the same area as the
affected access door. Press [COMMAND][4][6].
2. If using the D1255 keypad, when the keypad displays
CYCLE DOOR?, press [NEXT] once.
3. Using either a D1255 or D1260 keypads, select
UNLOCK DOOR?. The keypad then shows the current
status for all access doors programmed into the
system. Refer to
Figure 12 on page 20.
4. For test purposes only, swap the DIP switch address
on a known good D9210B (for example, Door 2) with
the affected D9210B (for example, Door 3). Refer to
Table 10 on page 19. Refer to Figure 13 on page 20.
By swapping DIP switch addresses, Door 2 becomes
Door 3, and vice-versa.
Continue monitoring the affected door number on the
keypad display.
Does the keypad still display “F” for the affected access
door number?
