The NC511 (NC-511) is a high power repeater for the Tek-CARE®500 Wireless Emergency Call System. The NC511 (NC-511) repeater allows greater distances between the Tek-CARE®500 Transmitters and Receiver. The Receiver’s transmitter offers up to four miles of open field range. This dramatic increase in range makes this transceiver a practical wireless solution for open-air installations such as campuses, multistory buildings, and other large wireless projects.

Wireless radio protocols and Signal Synchronization Technology™ allow the repeater to act intelligently, amplifying transmission from any Tek-CARE®500 transmitter while ignoring background noise.

Architects' & Engineers' Specifications:

The repeater shall be TekTone® NC511 (NC-511) or approved equals supplied by LEE DAN®

The repeater shall increase alarm transmission range. This repeater shall provide at least 200 milliwatts of effective radiated RF power. The repeaters shall have the ability to communicate with other repeaters, thus allowing for multiple repeaters to be installed as a microcellular network. Alarm and supervisory check-in signals from transmitters shall be maintained reliably with multiple repeaters in the system.

The repeater shall not require a home-run wire back to the receiver or panel. A repeater shall not identify itself during transmissions; therefore it must not bt used where a locator is required.
