Powering the TouchCenter
When the TouchCenter is powered from an auxiliary power supply,
always apply power to the control panel first and then the
TouchCenter. Failure to observe this sequence will result in improper
operation of the TouchCenter and may result in an ECP Error
indication.
Important Troubleshooting Information
When the TouchCenter cannot communicate with the alarm panel,
the message "ECP Error" will be displayed at the top of the screen. If
this message is displayed, check the following:
• Verify that the AUI type device is enabled in the control panel, and
that the ECP address in the TouchCenter matches the address
enabled in the control panel. Use a different address for each device.
(See "Programming the Control Panel" in Section 4 of the
TouchCenter Installation and Setup Guide.)
• If powering the TouchCenter from a power supply, make sure you
have a "common" ground installed (wiring connection between Power
Supply "gnd" and panel "Aux. power neg").
While an ECP Error message is being displayed, you must use the
TouchCenter access code of "4140" any time the TouchCenter
requests an authorized code. Once communication has been restored,
then use the standard panel installer code for all installer functions.
Programming with the TouchCenter
We recommend that you use either a standard alpha keypad or the
TouchCenter in Console Emulation Mode when programming the
control panel. When in the Console Mode, the TouchCenter emulates
an alpha keypad and the programming of the panel is performed
following the procedures provided in your panel's Installation and
Setup Guide.
General Notes
• You may check to see whether the Chime Mode is ON or OFF by
viewing the TouchCenter Operating Modes screen as described in
"Setting Operating Modes" in Section 4 of the TouchCenter
Installation and Setup Guide.
• The TouchCenter is defaulted to arm the system in the STAY
INSTANT mode when arming the system using the NIGHT button.
To change the TouchCenter so that it arms the system in a different
mode when the NIGHT button is pressed, see "How to Set the
