Two-Way Adjustment: The potentiometer marked "2-WAY VOL" controls the volume level of voice over the
phone line to the inside speaker during two-way communication or paging. Using a
small screwdriver, turn the potentiometer to obtain the desired volume. Clockwise
increases volume. This adjustment will not the affect alarm notification volume from the
speaker during an activation. Use of two-way voice is not evaluated for UL installation.
Upload / Download LED: At the top right of the board is a yellow LED labeled "U/D" which is illuminated when
there is a modem to modem connection during upload or download.
POWER LED: At the top right of the board is a red LED labeled "POWER" which is illuminated when
the system is receiving power.
STATUS LED: At the top right of the board is a green LED labeled "STATUS" which flashes to show the
microprocessor is functioning. An incoming ring detection will cause this LED to flash
very fast.
Dial LED: At the top right of the board is a red LED labeled "DIAL" which is illuminated during
digital communication and remote phone access. The Dial LED is used as a diagnostic
tool to analyze communication problems. The number of flashes after a failed attempt
correlates to the communication stage that caused the system to fail. See
"Communicator Diagnostics" for more information.
Phone LED: At the top right of the board is a green LED labeled "PHONE" which is illuminated when
the system's supervision of the phone line verifies a valid phone line on "R" and "T." If
the system does not confirm a phone line, the LED will turn off. Phone line failures can
be indicated at the keypad as well as sound a local alarm. Phone line restoration can be
communicated to the central station.
X-10 TW-523 Interface: Plug a standard RJ-12 cord into J5 on the middle right side of the board when using the X-
10 TW-523 (X-10 Pro PSC05) module for lighting options. The termination of the four
wire connection will be another RJ-12 jack plugged into the TW-523. The cord must
have four wires (see "X-10 interface Cord"). 2-wire cords will not work. Use of X-10 is
not UL listed for fire and burglary functions and is intended for hom automation. See
Control Channel section for programming information.
X-10 Interface Cord
A 4-conductor phone cord must be used to connect an X-10 TW-523 (X10-Pro PSC05) to the interface jack on the
control panel. Maximum cord length is 15 feet. The conductors must be in the following order:
