1 FUNCTION
 The detector is designed to measure the
temperature at the installation site and transmit
by radio to the Security Hub.
 Temperature control is carried out using a
built-in temperature sensor and / or a DS 18B20
temperature sensor (not included in the delivery
set) connected to the detector terminal block.
Maximum cable length - 3 m
ATTENTION! The terminal block must not be
used to connect other sensors!
 The range of temperatures measured by the
detector is:
a) built-in sensor – from - 30 to + 55 °С;
b) external temperature sensor DS 18В20 –
from - 55 to + 125 °С.
 If an external temperature sensor is connect-
ed, the measurement results are transmitted
alternately from each sensor.
The sending frequency is 12 sec. or 60 sec, set
by a jumper (see the table in p. 4).
 The detector operates only in radio mode 2,
the jumper on the R plug must be installed.
