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 you must get
approval from local fire officials 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
applications, 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 ACCEPT VERBAL APPROVALS, THEY ARE NOT VALID.

primary warning or monitoring system. Primary warning or monitoring systems should
always meet local fire and safety code requirements. The installer must also test the
system on a regular basis by instructing the end user in appropriate daily testing proce-
dures. Failure to test a system regularly could make installer liable for damages to the end
user if a problem occurs.
