The unit has two programmable and supervised voltage outputs (VO0-VO1),
intended for alarm devices (e.g. sirens, strobes, etc.). An End-Of-Line capacitor
(470nF) is to be mounted in the last device, alternatively, a capacitor (470nF) in up
to five alarm devices (T-off).
The unit also has a special voltage output (VO2) intended for fire door closing only.
The trigger condition "Fire Door Closing" and the controlling detectors have to be
programmed. The "fire door closing function" is described on page 101 and besides
that function, the output VO2 will also not be powered for approx. 30 sec. after:
The unit has two inputs, i.e. one for power supply (24V
For connections and examples, see drawings F733 & F737. Unit dimensions: (90L
x 70W x 32H mm. A plastic protection cover is attached. The cover's dimensions:
129L x 73W x 45H mm. The unit is intended to be surface mounted and for indoor
use in dry premises. When required, the unit can be mounted in a Waterproof box
(IP66 / 67).
The COM loop address is set with the Address setting tool 3314 / 4414 while the
unit is powered. The unit has an address label on which the programmed
technical address is to be written.
The Address setting tool 3314 / 4414 is also used for mode setting:
NORMAL mode: Used for 3364 in system FT1020G3.

Alarm devices (addressable sounders)
4477
Addressable siren. Replaces 3377, the new 4477 is similar to 3377 unit but it has
a built-in short circuit isolator, refer to section 9.1.4 Short circuit isolators
(addressable) page 64. The isolator does not use any COM loop address.
The power to the siren is supplied via the COM loop, i.e. the number of sirens is
dependent on the type and number of other units connected to the COM loop.
Three sound types (tones) and three priority levels are available.

The number of 4477 + 3379 units must be < 50 per COM loop.
The "/Mains OK input" (terminal 8) goes high, see below.
The COM loop communication is interrupted i.e. 3364 has no connection

VO0: Normally low or high (set via EBLWin), 24V
VO1: Normally low or high (set via EBLWin), 24V
