TekTone LI404B Description
The LI404B Strobe is a high-intensity remote visual signaling device for use with TekTone® Tek-ENTRY® Apartment Entry 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.
