3364 Addressable 2 voltage outputs unit. The unit is connected directly to the COM loop.
External 24 V
DC
supply is required (via a 3366AU unit or FT128).
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 alternativly 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 99 and besides
that function, the output VO2 will also not be powered for approx. 30 sec. after:
 the "/Mains OK input" (terminal 8) goes high, see below.
 the COM loop communication is interrupted i.e. 3364 has no connection /
communication with FT128.
The unit has two inputs, i.e. one for 24 V
DC
supply and one for "/Mains OK".

: From an external power supply (unit 3366AU or FT128)
 Mains OK: From an external power supply unit (3366AU). Normally low =
the main power source (230 V

For connections and examples, see drawings F733 & F737. The unit's 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 technical address is set with an 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 FT128.
6.1.3 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 6.1.5 Built-in Isolators page 63. 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.
63
Three sound types (tones) and three priority levels are available.
 Steady (continuous) 990 Hz
 Intermittent (pulsed) 990 Hz, 0.5s / 0.5s (1 Hz)
 Alternating (two-tone) 990 / 650 Hz, 0.25s / 0.25s (2 Hz)
61
Cont. 1 A, during 10 ms 1.4 A.
62
When the 24Vdc power to 3364 is supplied from FT128, this terminal must be connected to negative. To simulate “Mains Ok”
for 3364.
63
The number of 4477 + 3379 units must be < 50.
