ELECTRONIC FENCE ALARM |
|
Designed to alert you when the voltage on your electric fence drops below a preset voltage. It can be used on electric fence lines powered with any fence controller capable of producing and maintaining over 2000 volts. The alarm can be set to activate when fence line voltage levels drop to or below the 2000 volts or 4000 volts setting. For longhaired or hard to control animals such as sheep, goats and predators, it is suggested to set the alarm at the 4000 volt setting. The 2000 volt setting should be adequate for most animals. The EFA 1 comes equipped with a siren / light warning device. The siren / light device emits a high decibel siren (105 db @ 3.3 ft) and a bright flashing light. The siren / light device is visible and audible from great distances. With additional wiring (12/2 UL rated electrical underground wire, not included) the warning device can be placed up to 8000 feet from the EFA base unit. The alarm has other options such as turning on house lights, yard lights or dialing a telephone (autodialer). The voltage on the electric fence must drop below the alarm's preset voltage level (2000 or 4000 volts) for a period of 10 seconds before the alarm will activate. This should eliminate any unnecessary alarms due to animals touching the fence or periodic arcing due to something coming in contact with the fence for a short period of time. When the alarm activates, it will continue until the switch on the EFA base unit is placed in the off position. Make any necessary fence repairs before activating the alarm again. The alarm will also stop if the fence line voltage returns to a voltage level above the preset level for alarm activation. The EFA 1 can be used with a 12 volt transformer (sold separately) that can be plugged into a 110 volt outlet. For remote installations where electricity is not available, hook the power cord to the positive and negative terminals of a 12 volt battery. A Deep Cycle Marine battery rated at 85 amp hours or more is suggested. Battery should last approximately 3 months before having to recharge. Using a 12 volt battery source is useful during power outages, as the EFA 1 stays operational.
