8028 SIP Doorphone (G2) FW 3.2
INSTALLATION
EARTH GROUNDING MAY BE REQUIRED
This guide provides important safety information which should be read thoroughly before
permanently installing the product. Earth grounding is required for installations with door
station wiring that leaves the perimeter of a building due to the potential for over-voltage
fault conditions.
Note that this requirement does not apply when a door station is installed indoors
or on the outside wall of a building if the wiring runs directly into the building.
Earth grounding can be achieved by connecting the 8028 (G2) control unit power jack to
earth ground using either the supplied ground strap directly to a suitable ground point or
by use of the optional Algo 75-00004 24Vdc Power Adapter to socket outlet with a
protective earthing connection.
It is highly recommended that when an earth ground is required the control unit be
located in a restricted area and that the control unit be secured in place and cable ties
used to prevent accidental disconnect of the connection to earth ground. This connection
should be verified by a qualified electrician and routinely check as a safety precaution.
Under no circumstances can the Control Unit be disconnected from earth ground
while connected to outdoor wiring.
EMERGENCY COMMUNICATION
If used in an emergency communication application, the 8028 SIP Doorphone (G2) should
be routinely tested. SNMP supervision is recommended for assurance of proper
operation. Contact Algo for other methods of operational assurance.
WET OR OUTDOOR ENVIRONMENTS
The 8028 SIP Doorphone’s controller is intended for indoor locations with the Door Station
is intended for outdoor locations and may be subjected to spray or weather, provided the
rear wiring cavity is properly sealed to prevent water ingress.
Gaskets included with the Door Station may be effective against water ingress on some,
but not all surfaces in which case additional protective measures must be taken such as a
perimeter sealant.
CAT5 or CAT6 connection wiring to an IEEE 802.3af or IEEE 802.3at compliant
network PoE/PoE+ switch must not leave the building perimeter without adequate
lightning protection.
When the Intercom is connected to wiring that exits the building, there is potential
risk of lightning induced electrical surges or high voltages from fault conditions. To
reduce risk, outdoor wiring should be protected by Earth grounded conduit
whenever possible. Relay input and output connections must not leave the building
