  is not connected
• PP2 2 pin header. Shunt during Firmware Upgrade
  when UCM programming cable is connected
• JZ1 - JZ8 3x8 way headers - Insert shunt in
  the position nearest the terminals for the
  corresponding Zone 1 to 8 if no EOL resistor is
  used for the zone. Insert a shunt in the
  position away from the terminal block if Double
  EOL resistors 2K7 connected in series and 4K7 is
  connected across the contact.
• S12V shunt to permanently connect 12V supply to
  S12V so S12V cannot be swicthed off

14

  affecting any programming settings
• SPK (VR1) trimmer - adjusts volume of the siren
  on SPK/COM output (not BELL volume)

15
Shunts Analog Section

• KPSIR (J56) 2 way header - Volume setting for
  Siren sounds on Keypads. Shunt for louder siren
  volume. This does not affect the BELL volume or
  the volume of the siren on the SPK output
• J52, J53 - factory settings for echo cancellation
  tuning. Do not change. Default is J52 Shunted,
  J53 shunt across pins 2 and 3.

16
Settings Analog Section

• KPMIC (VR51) trimmer - determines microphone
  signal level from the Keypads. Affects keypad
  recording level and Intercom level. Clockwise to
  increase microphone signal level. Fixed in
  factory
• DPMIC (VR53) trimmer - determines microphone
  signal level from the Door Stations. Affects Door
  Station recording level and Intercom level.
  Clockwise to increase microphone signal level.
  Fixed at factory

17
Settings Analog Section

• ECHO (VR52) trimmer - factory adjusted for Echo
  cancellation. DO NOT adjust
• BATT (SW52) Pushbutton - This is beside the large
  heatsink and the large capacitor. Press to
  connect backup battery if connected without the
  AC voltage at AC14V turned on. If the AC voltage
  is off and a backup battery is connected, the
  battery voltage is not applied to the system
  until the BATT switch is pressed. Use a
  non-conducting tool, eg a pen to press this as it
  is not easily accessible

30
Security Check (Walk Test)

• Press F3,2 for Security Check
• All zones which are ON or activated are
  announced on all keypads. Zones which change to
  OFF are not announced
• Zones announced at the start are already ON, it
  means that the window or door is already open
• Alarms are not activated in this mode, so it does
  not test that the Zone type is programmed
  correctly

• Press Away to arm system
• Please exit should be heard
• Open and Close the front Door
• After 6 seconds system says Away Mode

Dial Test

• F3, 3 Dial Test dials to all programmed
  telephones (max 8) according to the phone type.
• The sounds of the dialing tones and the tones
  generated when call answered are heard on the
  keypad
• This is very useful for testing CMS dialout to
  hear the handshake and kissoff tones to verify
  that the call is going through
• Useful to check that dial out to mobiles phones
  are successful
• Any line problems eg no dial tone, busy tone can
  be heard

34
Troubleshooting

• Refer to Installation Manual Section 4
  Troubleshooting
