Description
The Isaacs RD810 Single Output Receiver continuously monitors the radio frequency band for signals from
its valid transmitter (the Isaacs transmitter that is specifically programmed to this receiver). The valid transmitter
signal causes the RD810 receiver to respond by switching its output relay per the programming established for the
valid transmitter. The receiver also provides a relay output for system faults including low transmitter battery
voltage and lost communication.

Site considerations
The Isaacs wireless controls have maximum range when used as line-of-sight communications. All units
should be mounted high enough to allow a minimum ten feet of clearance between the line of sight and the terrain
below and any intervening foliage. The line of sight should be clear of all metal buildings and chain-link fences, and
preferably clear of all buildings and foliage. Failure to maintain these clearances may reduce range.
The Isaacs PR810 Repeater is available for sites with significant obstacles or extreme range.
Installation
Mount the receiver and transmitter (models TD810-817) vertically, on rigid conduit masts, with the one-
inch NPT fitting at the bottom. Mount both units at least ten feet above grade on vibration-free solid structures.
The wiring may be spliced and extended only as specified in this install guide and in the transmitter supplement.
The units are weatherproof, but in some environments it is possible for liquids or gases to enter the unit
through the base fitting. Where there is such a possibility, before installing a unit on conduit, seal the base fitting
around the wires and grommet, with a non-corrosive curing RTV compound such as Dow 748 (Isaacs TS0658).
The transmitter is omnidirectional and, when mounted upright, may point in any direction. The RD810
receiver has better signal-detection capability on the front side (Isaacs label side). Mount the receiver so that the
transmitter is always within the 180 degree arc on the front side of the receiver.
