Alpha LI404B Emergency Call Light

The Alpha Communications/Tektone LI404B strobe adaptor is a high-intensity remote visual signaling device for use with apartment intercom stations that are powered by the PK543, PK292A, PK205 and PK104B type amplifiers. They can also be used on systems utilizing one or more PK502B multi-entrance switching adaptors. The LI404B strobe is primarily for use in locations where hearing-impaired persons require supplemental call notification, but can be used anywhere that a visual indication of an incoming call is desired. The bright strobe flashes once per second, for approximately 10 seconds, when an incoming call tone is detected. The LI404B strobe can be installed over most standard single or double gang flush electrical boxes or over double gang surface type boxes. It is not a weather proof device and should not be used in any outdoor locations. Installation is made easy by use of simple connections to the pre mounted circuitry and a complement of mounting hardware.
