WIRELESS TEMPERATURE
DETECTOR
«CN-Celsius»
Installation Guide
1 General information
1.1 Wireless temperature detector «CN-Celsius» (hereinafter,
«the Detector») is designed for the temperature measurement and
it’s control within the preset range and out-of-range temperature
messages sending via wireless two-way communication channel within
433.05 – 434.79 MHz frequency range by the
«CN-Contact-R» protocol.
The Detector is designed for operation with the any control
panel (hereinafter, «CP»
) which supports
«CN-Contact-R»
wireless
two-way communication protocol.
1.2 The Detector is powered from a main lithium power supply battery
СR123A type and СR2032 backup one.
1.3 Two temperature measuring and control channels:
Channel 1 – built-in signal processing unit (hereinafter, SPM);
Channel 2 – external temperature sensor (hereinafter, TS).
1.4 Two operating modes are available: single-channel mode
and double-channel mode. External TS should be hooked up to the
Detector if double-channel mode is chosen. Operational mode selection
is available during the Detector logging in the the CP.
1.5 The Detector generates and provides transmission of the following
messages:
- «Normal»
– the temperature is within the preset range;
- «Channel 1 out-of-range» – temperature out of range in channel
1 for 1°
or more;
- «Channel 2 out-of-range» – temperature out of range in channel
2 for 1°
or more;
- «Tamper»
– case or wall tampering;
- «Failure in channel 1»
– SPM failure in channel 1;
- «Failure in channel 2»
– TS failure in channel 2;

1.6 Two operating frequencies: main and reserve are used for the
Detector – control panel wireless data exchange. The Detector switches
to the reserve operating frequency automatically.
1.7 The Detector is designed for continuous and uninterrupted
operation.
1.8 The Detector is able to operate in standalone mode (ref. section
«
Standalone mode
»).
1.9 The preset limits of temperature range (the lower +17 °C, the upper
+27 °C) rated by the manufacturer are stored in nonvolatile memory
and may be changed by relevant control panel assisted command for
each channel apart.
1.10 The detector provides immunity to electromagnetic interferences.
1.11 The level of industrial interference generated by the Detector
does not exceed the norms established for the technical equipment
operated in residential buildings or connected to power mains of
residential buildings.

4 The Detector Construction
The Detector comprises the following elements: cover, base and
printed circuit board (PCB).
The cover (not shown) is fastened to the base (1) by latches located
on it’s end surfaces. For the cover opening push the latches by fingers.
At the front side of the PCB (2) the following entry is located: case
tamper (3), two-color LED indicator (4), connecting block for TS
switching (5), main power supply battery holder plate (6),
«
RESET
»
contacts (8), SPM (9), sound alarm (10), antenna (11). Backup power
supply battery holder plate and wall tamper are located on PCB back
side. The PCB is fixed on the base by means of trip (7) and hooks on
the opposite side of the base.

5 Sound and LED Indication
The Detector has the following indication modes:
- «Binding» procedure LED indication (procedure of logging in the CP);
- LED indication of the mode «Identification» is switched on by sending
relevant command from CP and remains active during 15 min or until
the case is opened;
- LED indication of the Detector state is switched on and remains
unchanged for 15 min after the case is closed under conditions:
a) other LED indication types (except the sound alarm) absence;
b) alarm «Tamper» message is not generated during this time period;
c) absence of command from the CP disabling the Detector state
indication.
Indication modes are listed in the Table 3.
