Rielta STZ-RK User manual

WIRELESS FLOOD DETECTOR
«STZ-RK»ver. 1
1 Product Overview
1.1 Wireless flood detector «STZ-RK» ver. 1 (hereinafter, the
Detector) is intended for detecting leaks of water from water-supply
pipelines or heating facilities and generating an alarm message
via a two-way communication by the «Rielta-Contact-R» protocol.
The Detector is intended to operate as a component of any control
panel (hereinafter, CP) supporting the wireless exchange protocol
«Rielta-Contact-R».
1.2 Water leaks control is ensured by measurement of an external
resistance between sensor terminals of the Detector.
1.3 Radio signals are exchanged within the 433.05 to 434.79 MHz
frequency range. The transmitter output power does not exceed
10 mW.
1.4 Two operating frequencies: main and reserve are used for the
wireless data exchange. The Detector switches over reserve operating
frequency automatically.
1.5 Radio exchange sessions are initiated by the Detector at a
preset frequency. The frequency settings are 10, 15, 30 sec, 1, 5,
10 min, chosen in the process of the binding procedure. The Detector
transmits alarm messages to the CP immediately.
1.6 The Detector power supply is provided by power supply batteries
placed inside it’s case: the main one and the backup one (CR2450).
1.7 The Detector state is displayed by two-color LED indicator.
1.8 The Detector generates and transmits the following messages
via a two-way communication:
- «Norm» – if the external resistance between sensor terminals value
is 200 kΩor more;
- «Alarm» – if the external resistance between sensor terminals
value is 100 kΩor less;
- «Tamper» – in the event of case tampering or the Detector removal
from the mounting surface;
- «Main Power Supply Low Battery» – under the main power supply
battery voltage drop below 2.8-0.4 V;
- «Backup Power Supply Low Battery» – under the backup power
supply battery voltage drop below 2.8-0.4 V.
1.9 The Detector is designed to operate continuously, around the
clock.

4 The Detector Design
The Detector comprises the base with the openable mounting
hole (7) printed circuit board (1) (PCB) installed on the cover. The PCB
comprises the following elements: main power supply battery holder
plate (2), «RESET» contacts (3), backup power supply battery holder
plate (4), sensor terminals (5), tamper contacts (6).

5 Indication
The Detector has the following indication modes:
- «Binding» procedure LED indication (procedure of logging in the CP);
- «Identification»indication mode –lights up by the relevant command
from CP and remains active during 15 min or until the case is opened;
- LED indication of the Detector state is activated after the Detector
cover is closed and remains active during 15 min under conditions:
- other LED indication types absence;
- alarm «Tamper» message is not generated during this time;
- absence of command from the CP disabling the Detector state
indication.
LED indicator modes are listed in the Table 3.

6 Binding with the CP
«Binding»mode is used for logging the Detector in the CP and service
information exchange.
6.1 Prepare the CP in accordance with CP reference guide.
6.2 Initially install the backup power supply battery to the holder
plate (4) on the PCB, thereupon install the main power supply battery
to the holder plate (2).
6.3 Periodical LED indicator blinking green is evidence of binding
process.
6.4 In case of mentioned above LED indication absence, short-circuit
«RESET» terminals for 2 – 3 sec.
6.5 The time limit for the binding process of the Detector is 100 sec.
To restart the binding procedure, short-circuit «RESET» terminals for
2 – 3 sec.
7 Communication Quality Appraising
7.1 To apprise the radio communication quality it is necessary to
act as follows:
- place initially backup and then main power supply batteries to the
correspondent holder plates;
- set the Detector on the assumed place of installation;
- push and then release case tamper.
7.2 After case tamper releasing the Detector generates case
tamper alarm message, transmits it via radio communication channel
and represents communication quality with CP by LED indication in
accordance with the Table 4.

8.2 Fasten the base to the mounting surface by means of double-sided
mounting tape. To ensure the Detector secure mounting act as follows:
- make sure, that the mounting surface is flat, dry and clean;
- remove protective film from the mounting tape working surface;
- press the Detector tightly to the mounting surface and hold it for
2 – 3 sec;
For the wall-tamper monitoring, the second screw should be fastened
in an openable hole (7).
