The TempAlert® TA-1 offers reliable and economical temperature protection for residential or commercial security systems. Simply wire units in parallel for simple, wide-area coverage. Ideal for computer rooms, residential/vacation homes, greenhouses, animal buildings or unattended buildings. Monitor high and low temperature limits by setting an acceptable temperature range with high and low limit arms.
Not for use in cooler/freezer monitoring, instead choose an EnviroAlert® with probe.
