equipment requiring 24 V DC with battery backup, e.g. the
3364 unit. It also has a "/Mains OK" output (normally low),
intended to be connected to the corresponding input on the 3364
unit.
A light grey metal housing (HxWxD, 288 x 400 x 95 mm).
There is space for two maintenance-free sealed Lead-Acid
backup batteries, 2 x 12 V, 7.5 Ah as the second power source.
Batteries with higher capacity (up to 60 Ah) have to be placed
outside the housing. There are cable inlets on the top, bottom
and back sides of the housing. Two compression glands are
attached.
The unit has a 24 V DC
equipment with up to 2.1 A or 0.85 A continuous current
consumption, at the same time as the battery charging is in
50
progress. In case of no battery charging, the continuous
current consumption can be up to 4 A.
It has a number of security functions, e.g. against to high
current output and to low battery voltage etc.
information, see the Technical Description and the Product
Leaflet.
The technical address is set with an Address setting tool (AST)
3314. The unit has an address label on which the programmed
technical address is to be written.
The Address setting tool 3314 is also used for mode setting:
NORMAL mode: Used for 3366 in EBL128.
2330 mode: Not used in EBL128.
2312 mode: Not used in EBL128.

in an attached base and the colour is white.
technology will secure the highest reliability possible. The
smoke detection chamber contains an IR LED and a
photodiode. Scattered light (i.e. reflection of infrared light) is
used to detect smoke. The smoke enters the detection chamber
through an insect filter and an optical labyrinth. Fire alarm will
be activated after three values over the fire alarm threshold
level. The detector has sensitivity compensation for
contamination. Transmission distance between Detector and
Base station is min. 40 m in open air. The Wireless smoke

The rated output voltage for the main power source (rectifier) is 24 V ±
1%. Max. ripple 500 mVp-p. The rated output voltage for the second power
source (the backup battery) is 18 – 28 V DC. NOTE! The voltage will,
however, decrease to approx. 15 V when the output will be switched off in
order not to damage the battery.

A current consumption of 0.85-2.2 A allows only the "low current
charging mode", i.e. the battery capacity can be up to 27 Ah.
A current consumption < 0.85 A allows the "high current charging
mode", i.e. the battery capacity can be up to 60 Ah.
