Open the catalog to page 21 INTRODUCTION TO THE JEROME 651 The Jerome 651 is a non-portable hydrogen sulfide gas monitor designed for perimeter and other outdoor locations. The 651 utilizes a removable 631-X to monitor gas concentrations. The 651 is protected in an insulated all-weather (except flooding) enclosure; it is AC powered and has built-in heat and air-conditioning for increased 631-X accuracy. The 651 can be remotely polled for up-to-date readings or left unattended to log readings for up to a year. A PC that is equipped with “Jerome Monitor Software” (JMS) and a radio modem serves as a Base Station and...
Open the catalog to page 52 WARNINGS (READ THIS BEFORE USING THE 651) • • • • • • • THE 651 IS NOT DESIGNED TO OPERATE IN HAZARDOUS LOCATIONS. THE 651 IS DESIGNED FOR ODOR MONITORING OF HYDROGEN SULFIDE. Read the “631-X Operation Manual” (P/N 700-0037) for specifics on the 631-X. Sample intervals under 30 minutes will result in a 631-X sensor life of less than 1 year. Follow local and national codes when installing the 651. It is recommended to use a ground fault circuit interrupter (GFCI) on the AC power circuit for safety in an outdoor environment. Do not allow rain to get inside the enclosure. In the 651, the...

Open the catalog to page 11Outdoor/External Antenna Setup If you have purchased the optional outdoor/external antenna for the 651, the standard Phantom antenna mounted in the top of the 651 is unscrewed and replaced with a lightning arrestor installed inside of the 651 enclosure. 1. Connect an appropriate cable from the lightning arrestor to the outdoor antenna. Refer to §6 OPTIONAL EQUIPMENT for information on the different cables available. See the diagram below for an example setup.
Open the catalog to page 122. The lightning arrestor must be grounded to provide protection. Attach the grounding strap to the connector of the cable from the lightning arrestor to the antenna. This is just above the lightning arrestor, on the outside of the 651 enclosure, as shown below. Use the Grounding Strap to ground the system to a metal water pipe running into the ground, grounding spike, or other appropriate means using #6 gauge bare copper wire. (Follow national/local codes). For additional protection, install a lightning rod as well. Connector of Cable from Lightning Arrestor to Antenna Grounding Strap...
