S-Quad
Speech (Sp)
The S-Quad Speech function is provided by stored messages on
a flash memory chip within the assembly. The standard flash
memory can hold up to 60 seconds of audio and additionally it
holds local complex attention tones, such as the bell and DIN
signals. Each signal output from an S-Quad Speech device
consists of an attention tone followed by a message. The
attention tone can be a local complex tone or a panel tone, such
as the standard 'nee naw' sound.

Description & Commissioning
Strobe (St)
Flasher LED
The Strobe utilises a high-power red LED that receives its power
from a super capacitor in the S-Quad assembly. The high light
output from the LED is made possible by the low impedance of
the capacitor. When compared with the conventional Xenon
flasher the S-Quad strobe outputs a lower level of light over
longer duration to achieve the same intensity. The strobe is
designed for installation on a ceiling and provides a wide viewing
angle to allow the light to be seen all around. As factory set the
strobe provides a pulsed output every 2s with signal 1, 1 second
with signal 2 and 1 second with signal 3, however the operation
of the strobe with the signals 1, 2 and 3 can be changed at the
commissioning stage. The strobe is synchronised with S-Cube
strobe installed in the same system.
The Disability Act 1995 recommends visual alarms, like S-Cube
and S-Quad, are installed in protected premises to warn
occupants who are hard of hearing.
A metal back box must be used for semi-flush mounting. The
earth continuity must be maintained throughout the whole loop.
The earth must be securely connected to the metal back box.
