UDS-3 is a control panel for any extinguishing systems: inert gas, CO2, water, dust, foam etc.
The new extinguishing management panel UDS-3 manages two discharge zones according to UNI EN
12094-1; each zone has dedicated input and output lines.
UDS-3 has a metallic box with LCD display to allow easy plant status view and different password level
protected keyboard for programming and local plant management.
Compatible with all NOTIFIER control panels available in commerce:
conventional fire control panels AM200, CFP12/24, NFS series, etc.
analog fire alarm control panels AM1000, AM2000, AM4000, AM6000, etc. since it has two output
modules and four input modules (for each zone) to send alarm and fault signals to the analog control
panel.
UDS-3 can be activated by:
two inputs for each zone that define pre-activation and activation conditions. Connections for
conventional control panels are also provided
analog control panels through Loop connection (one for each zone) for discharge activation and to
send alarms and faults directly to the control panel;
through manual push-button (for each zone).
UDS-3 is protected from over voltage, short circuits, electrostatic discharges,
UDS-3 USER INTERFACE FEATURES:
Mandatory LED lightings for each discharge zone;
Separate indications for each zone on alphanumeric display, related to pre-activation, activation,
release, fault. These indications can be accessed any time;
Instantaneous pre-discharge time (that can be set) count-down display
GAS label to show that discharge is in progress
Keyboard access to system and zone information
Graphical menu for programming/configuration
Menu voices have settable passwords of level 4, 3, 2 (consistent with EN54.2)
Through suitable remote repeater panel, signals from main panel can be duplicated (e.g. for locals
with more accesses).

For each input in the terminal board, the following “activation window” is valid. The only exception is for
Flowmeter and Manostat inputs that can have the alarm window instead of the stand-by one (for NA or NC
inputs) depending on the program.
All inputs are balanced with an end-line 2,7K-1/4W resistor.
ALARM 1 AND ALARM 2 INPUTS
Balanced inputs.
Terminal board inputs for conventional control panels connection.
An input activation brings UDS-3 in “pre-activated” condition; if this signal disappears, the panel gets back into
stand-by mode.
A further activation signal, present on another input, brings UDS-3 into “activation mode”.
MANUAL EXTINGUISHING ACTIVATION INPUT
Balanced input.
Terminal board input for connection with a manual activation push-button (Rapid Discharge) of extinguishing
system.
If activated for 3 seconds it brings UDS-3 into “active mode”.
EMERGENCY DELAY INPUT
Balanced input.
Terminal board input for connection with an optional mechanical device that can delay release, while active.
ONLY MANUAL EXTINGUISHING INPUT
Balanced input.
Terminal board input for connection with an optional key switch to allow UDS-3 to pass from “Automatic” to
“Manual” mode.
EMERGENCY STOP INPUT
Balanced input.
Terminal board input for connection with an optional ABORT button; its activation, before release begins, blocks
discharge.
MANOSTAT INPUT
Balanced input.
Terminal board input for connection with the output of a Manostat, for extinguishing control.
Activation of this input during release phase means that extinguishing cycle was ok.
Its activation during stand-by instead, brings UDS-3 into fault condition “Low pressure” for “Extinguisher loss”.
FLOWMETER INPUT
Balanced input.
Terminal board input for connection with the output of a Flowmeter, for extinguishing control. This input can be
disabled from programming menu.
If activated during standby condition, it means that extinguishing system has not been activated by UDS-3 but by
an external device (it can be due to a manual activation of the rapid flux valve). This brings UDS-3 into “release
mode”. Instead if UDS-3, after analysing input activation signals, gets into release status, this input is used to
manager extinguishing cycle.

NOTIFIER ITALIA Doc. M-205.1-UDS3N-ENG Rev A.1 UDS-3_manu
DESCRIPTION OF OUTPUTS ASSIGNED TO EACH UDS-3
EXTINGUISHING ZONE
PRE-ALARM DEVICE OUTPUT
Controlled output with a 2,7K-1/4W End-Of-Line resistor.
This output can be used to drive other devices of the extinguishing system, and it’s activated by a pre-alarm
signal. Being controlled, it’s particularly suitable for optical warning devices connections or for
optical/acoustic devices connection.
This output is activated during “pre-activated” condition, arisen by terminal board input or loop, and always
remains active. When UDS-3 goes back to standby condition this output switches off. This output can be
excluded.
N.B.: When pre-alarm output is activated polarity is inverted on the corresponding terminals.
SOUNDER OUTPUT
This is an output controlled by an End-Of-Line 2,7K-1/4W resistor.
Sounder’s acoustic signal is determined by extinguishing cycle phase.
These phases are determined by states in which UDS-3 is.
1. stand-by state: sounder OFF
2. pre-discharge state warning: sounder pulsing 0,5 sec ON - 0,5 sec OFF
3. active emergency delay state warning: sounder pulsing 1 sec ON - 0,5 sec OFF
4. release in progress status: sounder ON
Furthermore, sounder output can have the following functions:
1. Sounder output exclusion: sounder output can be excluded only if before actuators outputs are
excluded, in this case extinguishing output.
2. Sounder silencing: sounder output can be silenced when it is in “always on” status, that is
when UDS-3 is in “release condition” for that zone.
3. Evacuation: sounder output can be activated manually with continuous signal, to indicate an
evacuation of the zone, only if UDS-3 is in “standby” condition. Consequently in that situation
sounders can also be silenced. In case of evacuation command with alarm input activation,
sounder signals which phase is in progress.
N.B. When sounder output is active, polarity is inverted on the corresponding terminals.
