WIRELESS FLOOD
DETECTOR
«STZ-RK»
Installation Guide
1 Product Overview
1.1 Wireless flood detector «STZ-RK» (hereinafter, the Detector) is intended
for detecting leaks of water, water solutions, other current-conducting
non-aggressive liquids 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 The Detector comprises a Signal Processing Module (SPM) and flood sensors
«DZ-3V» (FS). The SPM has two connecting blocks for FS hooking up: «Loop 1»
and «Loop 2». Not more than two FSs can be hooked up in parallel to each loop.
1.3 The Detector is able to operate in two-loop or single-loop mode. The last
mode presumes the «Loop 2» status is ignored. The operation mode choosing
is available during the detector logging in the CP.
1.4 Radio signals are exchanged within the 433.05 to 434.79 MHz frequency
range. The transmitter output power does not exceed 10 mW.
1.5 Two operating frequencies: main and reserve are used for the wireless data
exchange. The Detector switches over reserve operating frequency automatically.
1.6 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 the binding procedure. The SPM transmits alarm messages
to the CP immediately.
1.7 Independent power supply of the Detector is provided by power supply
batteries placed inside it’s case: the main one (CR123A) and the backup one
(CR2032). If the main power supply battery is low, the Detector switches over
to the backup power supply source automatically.
1.8 The Detector generates and transmits the following messages:
- «Norm in Loop 1» – under the absence of liquid between the FS contacts
plugged to «Loop 1»;
- «Norm in Loop 2» – under the absence of liquid between the FS contacts
plugged to «Loop 2»;
- «Alarm in Loop 1» – under the presence of liquid between the FS contacts
plugged to «Loop 1»;
- «Alarm in Loop 2» – under the presence of liquid between the FS contacts
plugged to «Loop 2»;
- «Tamper» – under the case tampering or SPM removal from the installation
surface;
- «Failure in Loop 1» under the break of communication bus SPM – FS,
hooked to «Loop 1»;
- «Failure in Loop 2» under the break of communication bus SPM – FS,
hooked to «Loop 2»;
- «Main Power Supply Low Battery» – under the main power supply battery
voltage drop over 2.8-0.4 V;
- «Backup Power Supply Low Battery» – under the backup power supply
battery voltage drop over 2.8-0.4 V.
1.9 The Detector is designed to operate continuously, around the clock.
1.10 The Detector provides immunity to electromagnetic interference.
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.

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 » – lights up by sending relevant
command from CP and remains active during 15 min or until the case is opened;
- LED indication of the Detector state – lights up and remains unchanged for
15 min after the case is closed under conditions:
- other LED indication types (except the sound alarm) absence;
- alarm
« Tamper » message is not generated during this time period;
- the Detector state indication is ON upon the receipt of relevant command
from the CP.
LED indicator modes are listed in the Тable 3.

4 Design of the Detector
The external appearance of the SPM is shown in Figure 1.
The SPM comprises a base, a cover and a printed circuit board (PCB).
The front side of PCB (1) comprises: tamper (2), LED indicator (3), connecting
blocks (4) for connecting the FSs, main power supply battery holder (5), «RESET»
contacts (7), sounder (8), antenna (9). The backup power supply battery holder
and the tamper are located on the reverse side of the PCB. The PCB is fixed in
the base of the case by a latch (6) and grips on the reverse side of the base.
The case of the FS is watertight, it is
provided with sensing contacts and a
1.5 m cable for connecting to the SPM.
The FS is designed to be fastened to both
horizontal and vertical surfaces.

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 If it is necessary to log the Detector in double-channel mode, hook up TS
to the Detector as shown in Figure or short-circuit the terminals of the Detector
« - » and « Channel 2 » . For the single-channel mode neither hooking on, no short-
circuit is required.
6.3 Set the backup power supply battery to the holder plate on the PCB
other side.
6.4 Set the main power supply battery to the holder plate (6).
6.5 Periodical LED indicator blinking green is evidence of binding process.
6.6 In case of mentioned above LED indication absence, short-circuit
« RESET » terminals for 2 – 3 sec.
6.7 Successful binding procedure complying is indicated by LED indicator
lighting red for 2 – 3 sec.
6.8 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 « Stand Alone » mode
7.1 The Detector changes to stand alone mode upon the expiry of 100 sec
binding procedure.
7.2 During operation in the stand alone mode the Detector has no
communication with CP and it’s state is displayed only by means of LED and
sound indication (see Table 3).
7.3 During operation in the stand alone mode LED and sound indication is
always ON under condition of
« Tamper » message absence.
8 Communication Quality Appraisal
8.1 For radio communication quality appraisal it is necessary to:
- 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.
8.2 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.

9 Installation
9.1 Drill holes for fastening the Detector elements. You may use the FD and
the SPM base without the PCB for marking out the holes.
The FS should be located in the place, where the water spilled in the
detection zone close the sensor contacts. The FS installation with the terminals
downwards ensures generation of alarm signal over appearance the liquid sheet
with a thickness exceeding 1 mm. The FS installation with the terminals sidewise
provides easy access to the sensor terminals for removal of a liquid from the FS
surface between the terminals after the leakage elimination.
9.2 Fasten the FS on the mounting surface with screws or a water-resistant
glue. Fasten the SPM base on the mounting surface with screws. For the wall-
tamper monitoring, the second screw must be screwed in a hole under the wall
tamper. Install the PCB, connect the FSs to the loop terminals (the red wire to
the «+» terminal). Install the cover.
