For difficult situations, the battery-operated probe is your solution.  You do not have to worry about running long wire runs.  The only wire is the 22/2 AWG burial cable that attaches the probe to the processor.  If you can, this wire should be buried; however, if the location is too difficult, you do not have to bury the probe at all.  The system will operate fine.

This alarm is available in two models : A DWA-7-2000 ( 2000 ft. maximum transmission range) & a DWA-7-4000 ( 4000 ft. maximum transmission range). Both systems are available in a dual probe configuration and may be expanded to accept four probes ( each with a different sound by the use of peizo chimes).

If desired, the second probe may be substituted for a relay that will turn off the system for a short time as set by the customer. This is accomplished by means of a transmitter about the size of a garage door transmitter. The cost for this system will be the same as that of the dual probe.

Both models are backed by a one year factory warranty.

This system may also be adapted for a wireless temperature sensor to be activated at 35 or 40 degrees. Our recommendation is to use the 4000 ft wireless probe.
