1.5.3.6- Addressable sounder (SIRAY / SIRAYL / SIRAY+BSLC)
Microprocessed addressable sounder (with short-circuit isolator)
installed as another element inside the loop.
This sounder is manufactured in red plastic ABS.
It is a module with a single programming function respecting the
timing and combination of sensors that activate it. This sounder is
configured as a relay being able to act as a sounder.
The SIRAYL and SIRAY+BSLC variants additionally emits light
signals, where, SIRAY+BSLC is EN 54-23 certified (visual alarm
devices). The fact that these sirens emit light specifically does not affect
the programming of control panel. For this reason, these devices are
programmed in the control panel as it was SIRAY.
The standard configuration of the sound of the siren is shown in
Figure 8A according to EN 54-3 (sounder). In the same figure the
standard configuration of the light signal in the socket of the
SIRAY+BSLC siren according to EN 54-23 (visual alarm device) is
shown.
It is allowed to change the selection of the tone and light signal,
but this operation affects the power consumption of the sounder, and
therefore consumption elements equivalence of the device. Figure 8B is
a table showing equivalence to tone selections (standard 95-1m dB and
105 dB maximum sound intensity-1m) and visual signal (W-2,4-2,3/7,5).
Calculation can be made with the software of loop elements capacity
calculation.
It is shown the microswitchs position for standard and maximum
loudness at figure 8A, also including light signal for standard or
maximum power emission.
Internal wiring and other microswitch positions should not be
modified.
