Key features

• 194°F (90°C) fixed-temperature set point for outdoor and high-ambient-temperature environments
• Panel-mount (-EPM) base configuration supports surface mounting or standard electrical backbox installation
• Rate-compensated mechanical element corrects for thermal lag to maintain accurate response under varying heat rise rates
• All-weather housing rated for outdoor exposure including moisture and temperature extremes
• FM Approved for industrial property protection applications subject to FM Global requirements

The Thermotech 302-EPM-194 differs from the standard -AW model in its panel-mount base design, which provides additional mechanical flexibility for installations requiring surface-mount or backbox configurations rather than ceiling pendant mounting. This makes the -EPM variant suitable for wall-mounted applications in mechanical equipment enclosures, outdoor electrical rooms, and transformer housings where standard pendant mounting geometry is impractical. The 194°F rating addresses environments where maximum expected ambient temperatures exceed the safe threshold for 135°F detectors. Confirm mounting orientation and detection spacing with NFPA 72 and the Thermotech installation data sheet.

Verify panel/device family compatibility before ordering.
