INTRODUCTION
The TM1A Digital Alarm is a temperature monitoring and alarm device with user-programmable
high/low alarm set points and initial alarm delay time. Parameters are stored in non-volatile memory
and are maintained even when power is removed.
The temperature readout for the TM1A can be factory-set to ºC or ºF. It can also be readily
mounted into optional custom panels, for integration with existing equipment.
The TM1A is quite simple to operate. Plug in the unit, place the probe in the location to be
monitored, and the display will show the temperature of that location. Pushing the three buttons
allows the user to program both high and low alarm set points for the temperature range.
Optional features allow the unit to send temperature data to a recorder or (through an
appropriate translator), a computerized monitoring system. Please contact Accucold for details of the
many possibilities!
