• Remember the old WAPM door assignment!

25
General troubleshooting guidelines after
successful linking between PIM and Access Point

• Check the LED trouble indications inside PIM
• -Loss of RF communication, Low Battery, Tamper,
  etc.
• If there are trouble indications make
  corrections, else
• Functionally test the Access Point while it is
  properly connected to your access control system
• -When a valid card is presented the lock should
  release, and the LED indications on the reader
  should be normal
• If not, verify configuration of your access
  control software, if problem persists then
• Functionally test the Access Point using the CDT
  software
• -Manipulate the door status and REX, the picture
  of the door should update accordingly
• -Read in a card, the lock should release and the
  reader green LED blinks
• If the above is verified, then there are
  configuration/setup/wiring issues with your
  access control software
• If possible, temporarily connect a traditional
  reader to see if the problems go away

26
Access Point does not link to PIM

• If its a battery product make sure covers is
  properly installed on the Access Point
• Ensure PIM and Access Point are physically
  installed properly
• Test the Access Point location with
  Pre-Installation Test Kit
• Use the portable test reader and try to link with
  installed PIM
• If link occurs with the portable test reader,
  then the installed Access Point module is
  defective
• If link does not occur with the portable test
  reader, try linking the test PIM to the installed
  Access Point module (be sure to place the test
  PIM near the installed PIM location)
• If successful, set installed PIM to channel 15
  and try to link with the portable test reader (be
  sure to place the test reader near the installed
  reader). If it links, then use channel 15 on the
  installed PIM and try linking to installed Access
  Point module. If it does not link, then the PIM
  is defective.
• If unsuccessful, there may be large metal objects
  or shielded walls interfering with the
  communication between the PIM and Access Point.
• An interference search can be done using the test
  kit. Start the test kit linking at close range
  and slowly walk toward the installed Access Point
  location. When the test reader LED starts
  flashing red, this is where the signal is being
  lost. If this is the case, then move the PIM to a
  more suitable location and retest.
• If there are no metal objects in line, then try
  moving the test PIM a few inches and try to link
  to the portable test reader.

27
Access Point linked, but intermittent RF
communications occur after installation

• The RF environment is changing causing
  intermittent interference
• Try to re-link (if a battery product, close the
  door after linking starts)
• If linking occurs with door open but not when
  door is closed, then try
• Changing the RF channel on the PIM (with
  dipswitches), then try to re-link
• Move the PIM closer to the Access Point
• Implement Dynamic Channel Switching (with the CDT
  software)
• Note, on battery products, battery life is
  reduced by approximately 30.

28
Invalid reader data received by access control
system PIM-485

• Functionally test the Access Point using the CDT
  software
• Manipulate the door status and REX, the picture
  of the door should update accordingly
• Read in a card, the lock should release and the
  reader green LED blinks
• If the above is verified, then there are
  configuration/setup/wiring issues with your
  access control software
• If possible, temporarily connect a traditional
  reader to see if the problems go away
• Use the CDT, version 1.53 or higher, to decode
  data received by the PIM. If incorrect, the
  problem is at the Access Point module or reader.
• Check for correct card code conversion of the
  Wireless reader using the CDT
• Check card format setting in the access control
  system

29
Invalid reader data received by access control
system PIM-TD2

• Check the data wire connections from the PIM to
  the access control system including reader
  negative to PIM ground and data lines not
  reversed.
• Check for correct shielded cable with drains
  properly terminated
• Functionally test the Access Point using the CDT
  software
• Manipulate the door status and REX, the picture
  of the door should update accordingly
• Read in a card, the lock should release and the
  reader green LED blinks
• If the above is verified, then there are
  configuration/setup/wiring issues with your
  access control software
• If possible, temporarily connect a traditional
  reader to see if the problems go away
• Check card format setting in the access control
  system
• Check for correct card code conversion of the
  Wireless reader using the CDT
• If the other side of the PIM is working properly,
  then try temporarily swapping the connections at
  the PIM to determine if the PIM is defective

30
Access granted by EAC but Access Point indicates
access denied PIM-485

• Functionally test the Access Point using the CDT
  software
• Set to Grant Access, read in a card, the lock
  should release and the reader green LED blinks
• If the above is verified, then there are
  configuration/setup/wiring issues with your
  access control software
• If possible, temporarily connect a traditional
  reader to see if the problems go away
• If the units work properly on the CDT, then
  extend the First , Delay and Retry and
  retest with the EAC. If extending the query time
  works, the following are the recommended
  parameters to change
• For battery powered Access Points adjusting
  First and Delay are preferred to prevent
  shortened battery life
• For WRIs adjusting Retry is preferred to
  minimize unlock response when the panel response
  is faster on any given request to unlock
• If the Access Point module does not unlock in any
  of the scenarios above and no other problems are
  found, then the Access Point module is defective

31
Access granted by EAC but Access Point indicates
access denied PIM-TD2

• Check EAC relay input to the PIM STK-NO and
  STK-COM
• Temporarily place a short across STK-NO and
  STK-COM at the PIM, when a valid card is read, an
  Access Point should unlock, if it does, then
  Wireless units are functioning (verify wiring and
  configuration of your access control software)
• Check that the PIM is receiving the relay input
  with a DC voltmeter across STK-NO and STK-COM.
  This should read 5 VDC with the relay open and 0
  VDC with the relay closed.
• Functionally test the Access Point using the CDT
  software
• Set to Grant Access, read in a card, the lock
  should release and the reader green LED blinks
• If the above is verified, then there are
  configuration/setup/wiring issues with your
  access control software
• If possible, temporarily connect a traditional
  reader to see if the problems go away
• If the Access Point module does not unlock in any
  of the scenarios above and no other problems are
  found, then the Access Point module is defective

32
Card data is corrupted to the EAC and/or false
door status, requests to exit, and troubles
reported by PIM

• Verify CDT configuration settings
• Verify proper wiring, grounding and drain
  terminations
• Make sure the specified shielded cable or
  equivalent is used to connect the PIM to EAC and
  to connect the WRI to reader and status switches.
• PIM ground, EAC reader ground and status input
  ground must be terminated together at the EAC.
  The exception is when slave relays are used on
  PIM status outputs to supervised EAC inputs.
• Terminate the drain at the EAC and let open at
  the PIM.
• Terminate the reader cable drain at the WRI
  reader GND.

33
Battery Lockset or Exit Device does not react on
a card read

• Check reader tamper switch engagement
• A reader tamper disables the reader it appears
  dead
• PIM-TD2 reports a trouble and flashes the trouble
  red LED 3 times
• PIM-485 reports a tamper
• Make sure reader cover has foam spacer to
  reliably activate the switch
• Make sure the reader cover is properly seated and
  screws are snug
• Test reader by holding the tamper switch down and
  attempting a card read
• If LEDs start flashing 20 sec after read, then
  Request to Exit is shorted (and the reader thinks
  you are trying to link with a PIM)
• Check for low battery voltage

34
Battery product fails to read cards or is
intermittent

• Proximity Card Readers
• Card presentation technique is critical
• Card must be presented directly in front of
  optical window, do not wave card in front of
  reader
• Read range may be reduced in sunlight
• Check for low battery. The prox card read is
  typically the first function lost with a low
  battery.
• Initial low battery symptom is extra time
  required between card reads
• Mag Stripe Readers
• Teflon shim must be in place for the card present
  switch
• Make sure the reader is for the correct track to
  read the data
• Data must be in track 2 format (75 bpi)
  regardless of track used
• Note actions from the last read must be
  completed before the next card can be read
• If possible replace the reader with a known good
  reader, if problems persist, possible bad
  transceiver

35
Battery Lockset or Exit Device does not reliably
lock/unlock although the green and red LEDs
provide correct indications

• May have incorrect Motor configuration. Using the
  CDT make sure the settings are as follows
• WEXK Motor 1
• MIRL Mortise (Best) Motor 2
• MIRL Mortise (SafLok) Motor 3
• MIRL Cylindrical (Marks) Motor 4
• WA5600 Series Mortise Motor 4
• WA 993 Exit Trim Motor 4
• WA5200 Series Cylindrical Motor 5
• Motor runs in one direction only (should run to
  unlock, and then again to relock)
• Transceiver Assembly is defective
• Motor does not run in either direction
• Defective lock or Transceiver Assembly

36
PIM CR15 does not illuminate with power applied
and the other LEDs are not normal

• Momentarily depress the PIM Reset switch, S3
• Check that the input voltage is between 7.5 and
  14.5 VDC
• Check ripple on the input voltage on an AC true
  RMS voltmeter, the ripple should be no more than
  tens of mV
• If none of the above are the case, then PIM is
  defective

37
PIM sometimes resets on its own or locks up

• Check the power supply. It must supply at least
  300 mA at 12 VDC and never drop below 7.5 V or go
  above 14.5 V Note An unregulated 12 VDC supply
  output voltage varies with input voltage and load
• Check the ripple on the power supply with a true
  RMS AC voltmeter, the ripple should be no more
  than tens of MV
• If neither of the above are the problem, then the
  PIM is defective

38
Fail safe electric strike or mag lock controlled
by a WRI/PIM-TD2 remains unlocked all the time

• The EAC normally open relay contact must be used
  in all cases with a PIM-TD2/TD4, independent of
  the type of locking mechanism
• Use the WRI STK-NC and STK-COM to control a fail
  safe electric strike or mag lock

39
Card reads work fine but remote commands from
access control system do not

• The Access Point module is in control of RF
  communications with the PIM, and only
  communicates during a heartbeat or physical use
  of the lock (card read, REX, etc.)
• WRI
• Use the CDT software to reconfigure the default
  heartbeat from 10 minutes to 1 second, commands
  from the access control system will then happen
  within a second
• Battery powered products
• Kept in sleep mode almost all the time to extend
  battery life (minimum heartbeat setting is 10
  seconds, this will greatly reduce battery life)
• For a buzz-in application, install optional
  Request to Enter switch where the person at the
  entrance pressing the button to wake up the unit
  to accept the buzz-in command
• All units have provisions for the Request to
  Enter built in. Only a different reader cover,
  with a built in switch is required to add the
  function.

40
Battery Portable Reader (WPR2) with proximity
reader depletes battery packs prematurely

• Do not store units with readers facing each other
  within 8 of each other.
• Do not store with the readers facing a surface
  within 8.
• Do not store with the reader facing directly into
  the sun.
