5 Annunciator Design
The annunciator outside view is shown in Figure 1.
The annunciator consists of a base (1) and case (4). The base
comprises the oval holes (2) for it’s fastening to the mounting surface.
The case is fastened to the base with latches (3).
There is a two-color LED indicator (5) on the front surface of the
case. There are contacts (6), the main power-supply battery holder
(7) and the backup power-supply battery holder (8).
1 Product Overview
1.1 Wireless sound alarm annunciator «Trubach-RK» (hereinafter,
the annunciator) is intended for informing people about a fire or other
emergencies by generating an audible alarm.
1.2 The annunciator is intended for operation as a component of a
system that is operated by a control panel (hereinafter, CP), supporting
«Rielta-Contact-R» wireless two-way data exchange protocol.
1.3 The annunciator is switched on and off by means of CP, and it’s
operation modes are assigned by commands from the CP.
1.4 The annunciator monitors and transmits messages upon removal
from it’s base or upon discharge of both main and backup batteries.
1.5 The following rates of control radio exchange may be assigned:
10, 15, 30, 60 sec, 5 or 10 min.
1.6 The annunciator can operate in a continuous or pulsed
audible-alarm modes.
1.7 Pulse-mode parameters can be set by the user in the process
of the annunciator adjustment.
1.8 The annunciator operation mode is displayed by a two-color
LED indicator.
1.9 Two frequencies in the 433.05 to 434.79 MHz frequency range
are used for wireless signal exchange with the CP
–
the main frequency
and the reserve one. The annunciator switсhes to the reserve operating
frequency automatically in case of radio-frequency interference on the
main one. Transmitter power does not exceed 10 mW.
1.10 The annunciator is powered by two CR123A batteries, the main
and the backup one.
1.11 The batteries’ respective service-time capacities in a standby
mode (with a signal-monitoring interval of at least 30 sec) are as follows:
- main power-supply battery – at least 60 months or at least 2 months
in continuous operation mode;
- backup power-supply battery – at least 2 months.
1.12 The annunciator is designed to operate continuously around
the clock in closed premises of residential and industrial buildings
and structures.
1.13 The annunciator is resistant to the impact of electromagnetic
interference.

4 Informativity
The annunciator generates and transmits the following messages
to the CP via wireless communication:
- «Norm»;
- «Tampering»;
- «Main power-supply low-battery»
–
if power-supply voltage drops
below (2.4 ± 0.2) V during a regular communication session;
- «Backup power-supply low-battery»
–
if power-supply voltage
drops below (2.4 ± 0.2) V during a regular communication session.
The annunciator displays one of it’s operation modes as specified
in Table 3 (LED indication).
