Description
The 400 Series thermal rate-of-rise with fixed heat detector contains a unique dual thermistor heat sensing circuit to provide maximum performance and solid state reliability. The 60-1027 is designed to initiate an alarm at 135°F and to respond to a temperature increase in excess of 15° per minute. This enables the heat detector to communicate an alarm to the central control panel prior to reaching the static set point for these high rates of rise, providing a timely response to both rapid and slow temperature increases. THis model should be used in applications where rapid response is desired and where rapid temperature increases would only be caused by a fire emergency.
