GENERAL DESCRIPTION
The combination heat detector is a conventional fixed temperature detector, category A1R. The detector
will give an alarm at a certain fixed temperature (59 °C) and/or at a certain temperature rise, "rate-of-
rise" function.
Used in system EBL512 G3, EBL128, and EBL512.
The unit is intended for indoor use and in dry premises.

DETECTOR
The sensing element is a thermistor. The detector and will give an alarm within a response temperature
range.
Static response temperature

54-65 °C
The rate-of-rise function (deltaT) will detect a fast temperature rise > 6 °C per minute.
3.1.1
LATCHING
The detector is latching. The detector will not be automatically reset if the temperature, after the alarm,
falls below the detector's static response temperature. The detector's LED and a connected external
LED will be lit until the detector is reset via the c.i.e.
