1. Introduction
The IP VisorALARM PLUS 2U receiver is designed to be both a desktop and a rack device. In either
case, in order to achieve correct installation, please follow the recommendations given below:
BEFORE CONNECTING THE DEVICE PLEASE READ THE FOLLOWING
INSTRUCTIONS CAREFULLY.
1.1. General installation conditions
Conditions
Bear in mind the following recommendations:
1. If the installation is UL listed, install the device in a 19” rack or box with a locking rear
access door.
2. Excessive cold and heat should be avoided, as should humidity and dust. Direct exposure to
sunlight should be avoided as well as other heat sources. The device should not be placed
amongst papers, magazines or other elements that could hinder natural air circulation.
3. The device should not be placed very close to strong electromagnetic fields such as speakers,
engines, etc.
4. Knocks and/or strong vibrations should be avoided during transport, operation and storage.
Power supply
The VisorALARM PLUS 2U device does not require special conditions as regards voltage stability or
protection against power malfunctions as it is already protected.
To avoid electric shocks, residual current circulation and other unwanted effects, also affecting
communications, the following is recommended:
•
It is highly recommended that all interconnected communication devices be plugged
to THE SAME GROUNDED POWER OUTLET, which should at the same time be
of good quality (lower than 10ohms).
•
Whether the workplace is provided with an uninterrupted power supply system
(UPS), regulated supply or it is independent from the rest (such as lighting, etc.); it
is highly recommended that all data devices should be connected to the same power
source. This will avoid operating and premature aging problems of drivers and
other components.
•
For UL listed installations the device must be installed in an Alarm Central which is
UL Listed where an independent generator provides uninterrupted power supply to
all the equipment. It is also necessary to connect an uninterrupted power system to
the device which permits it to carry on operating for at least 15 minutes.
