MODEL 1100329 TELEPHONE INTERFACE BOARD ADJUSTMENTS
All adjustments must be made in the following order:
SIDE TONE ADJUSTMENT: To adjust the side tone, the phone line must
be connected to the
unit. Infinity B Units: Adjusting the side tone balance is unnecessary.
1. Enter programming mode: Enter three (3) asterisks “ÃÃÔ followed by the six (6) digit
password. Multi-Link Units: When adjusting the first unit (for Infinity “S” or “M” only) or a
secondary unit of a multi-link chain, enter a password of “000000”.
2. In programming mode, press “69 + # (or ENTER)” on the keypad. The unit will connect to the
phone line. You will hear two consecutive beeps followed by the modem carrier tone.
3. Locate the -080 daughter board.
4. Adjust LINE BAL 1 until the tone is at its lowest level. Use an adjustment tool with a 0.1” wide
blade.
5. During adjustment: (a) You may hear the recording of an operator’s voice. Disregard it.
Adjusting LINE BAL 1 will not vary the operator’s voice level. (b) If the system times out
(default = 30 seconds), repeat step 2 and continue to adjust the side tone until minimum sound
level is achieved. The system time out will not affect prior adjustments. (c) Multi-Link Units:
When adjusting the first unit (for Infinity “S” or “M” only) or a secondary unit of a multi-link
chain, after completing each Line Balance adjustment, repeat steps 1 and 2 and continue to
adjust the side tone balance. Exiting and re-entering programming mode will not affect prior
adjustments.
6. Perform the same procedure on LINE BAL 2.
7. Confirm that LINE BAL 1 is still adjusted to the lowest tone level.
MIC. SENSITIVITY: The microphone’s sensitivity may be adjusted on the daughter board at MIC
SENS (see Figure 16). The mic. sensitivity affects the volume heard by the tenant. NOTE: Use
an adjustment tool with a 0.1” wide blade.
INSUFFICIENT VOLUME: The volume may be raised or lowered by adjusting the "SPEAKER
LEVEL" pot.
CLICK LEVEL: Adjust the click level as follows:
1. Set the "CLICK LEVEL" pot (see Figure 16) to the center of its range.
2. Enter a directory code of a tenant with a rotary-dial telephone.
3. When they answer, ask them to dial a "9". The "CLICK" LED should flash until the strike relay
opens the door and the board emits a click.
4. If the relay doesn't click and the "CLICK" LED doesn't flash regularly, turn the "CLICK LEVEL"
pot clockwise and repeat steps 2 and 3 until both responses are received.
5. If the relay clicks and the "CLICK" LED stays on or doesn't flash regularly, turn the "CLICK
LEVEL" pot counter-clockwise and repeat steps 2 and 3 until both responses are received.
