5. INSTALLATION
5.1
Prior to installation
Please perform the following before beginning installation:
5.2 Important Information
●
Qualified Personnel Only
●
Door station and roadside phones can be supplied with power supply options, which may
require connection of the power supply to an AC mains supply. Qualified personnel must
only perform installation and maintenance. Contact Dallas Delta if installation is required.
●
Test tools required
●
During testing and commissioning of the telephone it is recommended to use a laptop to
connect to the internal USB port. Configuration can also be performed via the keypad fitted
on the rear, or via SMS text messages.
●
Avoid contamination during installation
●
All possible measures must be taken to ensure water, fluid or dust does not contaminate
the internal components of the telephone whilst unpacking, preparing and installing the
telephone. Failure to do so may invalidate your warranty. Please retain and screws removed
during installation or maintenance – make sure the correct screws are refitted to ensure the
integrity of any seals.
●
Emergency Services warning
●
If the telephone is configured so that it cannot make a direct call to emergency services,
check with your telephone service provider or infrastructure maintainer whether it is
necessary to warn users and if so, provide a suitable warning notice.
5.3 Configuration
The unit can be configured through a web interface as described in the Web Interface
subsection.
