Reliable & Economical Temp Protection

The professional looking MTA-1 Mechanical Temp Alert adds reliable and economical temperature protection to your residential or commercial security system. The design can be used anywhere the monitoring of high and low temperature limits is critical. The unit allows you to separately zone out high and low temperature alarm signals. The MTA-1 requires no power for operation. Simply select an acceptable temperature range by setting the adjustable high and low limits from +32 to +100 F (0 to +38 C). If temperatures in the monitored area rise above or fall below the set limits, the temperature indicator contacts one of the preset limit arms providing a dry contact closure, which can like a switch be used to turn on an existing alarm panel, telephone communicator, or wireless alarm system.

Important: Install a Temp Alert on every level of your home or business to adequately protect against freezing.

Do not use for freezer or cooler monitoring. Instead use a Digital Temp Alert unit with a remote sensor probe.
