Fire alarm systems
Addressable siren
3377
• High sound output but low current consumption
• Three different tones and priority levels
• Connected directly on the COM loop
General
The siren is a general purpose sounder that
consists of a horn (incl. all electronics) and a
back box, which has double cable entries. It
is made of red ABS plastic. The COM loop
is connected directly to the siren via a plug-
in 4-way terminal block (2 in/2 out).
High sound output
The siren has a high sound output but a low
current consumption. The volume can be
adjusted via a potentiometer.
Tones
Three tones are available:
• Continuous 990 Hz
• Pulsed (Intermittent) 990 Hz,
0.5s / 0.5s
• Two-tone (Alternating) 980/645 Hz,
0.25s / 0.25s
Priority levels
Three priority levels are available in system
EBL512 and two in system EBL128. For
each level an output control expression and a
tone is programmed (via Win512 / Win
128).
The siren can, for example, be used for pre-
warning, fire alarm and general fire alarm,
with a different tone for each type of alarm.
Address & Mode setting
For COM loop address setting, the address
setting tool 3314 is used. The siren has an
address label where the address is to be
written. 3314 is also used to set the mode:
• NORMAL mode: 3377 (3377 in
Win512 / Win128).
• 2330 mode: Can not be used.
• 2312 mode: Can not be used.
Miscellaneous
The address setting tool 3314 is connected
directly to siren's connectors when the
terminal block is unplugged.
The siren is power supplied via the COM
loop, i.e. the number of sirens is depending
on the type and number of other units
connected to the same COM loop.
Product applications
Used in the systems EBL512 (SW version >
2.2) and EBL128. The siren is intended for
indoor use and in dry premises.
