Warnings and Cautions
WARNING
Before installation, TURN OFF the external circuit breaker which supplies power to the
system.
Before connecting the device to the power supply, verify that the output voltage is within
specifications of the power supply.
Do not apply power to the system until after the installation has been completed.
Personal injury or death could occur, and the equipment could be damaged beyond repair
if this precaution is not observed!
WARNING
Fire Safety and Liability Notice
Never connect card readers to any critical entry, exit door, barrier, elevator or gate without
providing an alternative exit in accordance with all fire and life safety codes pertinent to
the installation. These fire and safety codes vary from city to city and approval from local
fire officials is required whenever using an electronic product to control a door or other
barrier. Use of egress buttons, for example, may be illegal in some cities. In most applica-
tions, single action exit without prior knowledge of what to do is a life safety requirement.
Always make certain that any required approvals are obtained in writing. DO NOT AC-
CEPT VERBAL APPROVALS, AS THEY ARE NOT VALID.
Northern never recommends using the PRO-2200 or related products as a primary warning
or monitoring system. Primary warning or monitoring systems should always meet local
fire and safety code requirements. The installer must test the system on a regular basis
and instruct the end user in appropriate daily testing procedures. Failure to test a system
regularly could make installer liable to the end user for damages if a problem occurs.
WARNING
EARTH ground all enclosures, for proper installation.
EARTH ground can be obtained through the power supply or by grounding the cabinet,
BUT NOT BOTH!
WARNING
Use suppressors on all door strikes. Use S-4 suppressors for installation. Northern
Computers recommends only DC strikes.
