The LI404B Strobe is a high-intensity remote visual signaling device for use with TekTone® Tek-ENTRY® ApartmentEntry Systems that use either the PK543A Amplifier/Relay/Power Supply or the PK205 Amplifier/Relay/Power Supply.

The unit is primarily for use in locations where hearing- impaired persons require supplemental call notification, but can be used anywhere a visual indication of an incoming call is desired. The bright strobe light flashes for approximately 15-20 seconds when an incoming call is detected.

The device can be installed in most standard single or double gang electrical boxes or similar indoor openings. It is not a weatherproof device and therefore should not be used for any outdoor applications. Installation is facilitated by the use of simple connections to the pre-mounted circuitry and a complement of mounting hardware. The LI404B Strobe Light portion meets ADA and UL® 1971 requirements.
