Introduction This device is a radio transceiver. It receives signals from existing ITI transmitters or other transceivers. It transmits signals to other base station transceivers. A hardwired bus provides a data link to an external board or a security panel. Both the receiver and the transmitter operate as frequency hopping spread spectrum (FHSS) links using the 902-928MHz ISM band. We are requesting Certification under FCC Rules, Part 15, Subpart C, Paragraph 15.247. 12VDC power is supplied to the device via either a hardwired bus connection or a Class 2 transformer. Please send comments/suggestions on the report to [email protected]. Grantee Code: B4Z 2.
