FUNCTIONS
When in alarm status the ECHO siren emits a
continuous high modulated frequency sound.
The modulation extremes (1300 and 2000 Hz)
have been selected to generate a high note,
which is particulary bothersome to the hearing,
and a low note that can be heard at a consid-
erable distance.
If alarm status continues for over 7 minutes
(the maximum alarm time), the acoustic signal
is automatically inhibited, whilst the flasher re-
mains active. Removal or breakage of the
flasher automatically signals tamper status to
internal circuit of the siren. The flasher is inhib-
ited if the battery is not fully charged, in this
case the remaining power is utilized to sound
the siren.
The siren starts when its power voltage fails on
the +N terminal or when -A terminal is short-
circuited to ground. The alarm ceases when
the previous conditions are restored (voltage
on +N and -A terminal disconnected). The si-
ren is also protected against tamper by two mi-
croswitches (fig. 4):
Ø the first (MS1) is on-board, and is activated
when the metal inner cover is removed;
Ø the second (MS2) is fixed on the wall with the
siren, its lever is held in position by the srew
used for closing the policarbonate box.
Therefore, the tamper circuit is activated
when the siren is pulled off the wall or the box
is removed.
These two microswitches send tamper signal-
ing to the internal circuit of the siren, or to the
control panel, by means of the S and S2 termi-
nals.
