  • Page 6: Introduction

    Model 5052RD-OP1 ALERT1 Receiver/Decoder Option receives ALERT1 radio data transmissions from remote sites and provides a TCP/IP data output to the base station computer. The ALERT1 Receiver and Decoder are mounted inside the 5052RD-K Receiver/Decoder desktop enclosure. Model 5052RD-OP2 ALERT2 Transmit Option transmits ALERT2 radio data packets to remote sites using an additional transmit radio with its own antenna connector.

  • Page 7: Installation

    Radio Path Survey. 2.1.2 5052RD-K The 5052RD-K ALERT2 Receiver/Decoder enclosure should be located near the antenna tower to reduce the length of the RF transmission line and the associated RF signal loss. It is recommended that a lightning arrestor with ground lug (optional) be placed between the ALERT2 receiver back panel BNC connector and the antenna to protect against lightning damage.
