Digital TempAlert 4-zone (DTA-4)

[PN# **DISCONTINUED**]

Part #1105. Four zone temperature monitoring - Microprocessor controlled.


The model DTA-4 offers precise temperature monitoring of four channels (zones) through microprocessor-controlled console. It scans and updates each zone 15 times per minute to monitor for potentially damaging temperature changes.

The DTA-4 is capable of measuring any temperature from -67 to +300 F (-55 to +150 C) based on your choice of remote sensor probe (see accessory options). If temperature in any of the monitored areas rise or fall below your preset limits, the unit will provide a relay contact change which can activate any type of alarm panel, telephone dialer, wireless alarm system, etc.

This model has been discontinued. Please use the EnviroAlert EA400 as a replacement.
