Temperature Sensor - AJAX FireProtect 2 User Manual

volatile particles inside the chamber and respond only to smoke, ignoring
vapour and steam.
The smoke chamber in FireProtect 2 is protected from dust, dirt, and insects.
Even if dust gets inside and settles, this does not threaten or impair re
detection. The optical system is designed to prevent non-volatile particles from
getting within the eld of both blue and infrared LEDs at the same time. So that
situation does not cause a false alarm.
The HazeFlow 2 software algorithm also protects against false alarms. When an
alarm is detected, the algorithm additionally processes the data received from
the detector and con rms the alarm.

Temperature sensor

Two built-in class A1 thermistors detect a rapid rise and exceeding the
temperature threshold in FireProtect 2. The thermistors of this class notify of
alarms when a rapid temperature rise or static temperature is detected in the
range of +54°C to +65°C.
The thermistors are mounted outside under the front panel of the detector. This
allows you to respond to threats faster than when the sensors are inside the
detector enclosure.
FireProtect 2 will reports that the temperature threshold has been exceeded as
soon as its value exceeds +64°C. The detector will reports a rapid temperature
rise if the indicator increases by 10°C within one minute. If the temperature
indicator rises sharply by 20°C or more, the detector signals immediately.
Test/Mute button
The Test/Mute button is located under the front panel of the detector. This is a
mechanical button. Тo activate it, press lightly on the central part of the front
panel with your hand or a suitable item if the detector is installed in a hard-to-
reach place. For example, you can do this with a mop handle.
The button performs several functions:
In normal mode, it starts the detector self-test .
