UDS-3 is a control panel for any extinguishing systems: inert gas, CO , 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.
Environmental conditions Operating temperature: - 5° C / + 40° C. Relative humidity: 10% - 93% (without condensate). Storing temperature: -10°C / +50°C UDS-3 Power The control panel is powered by mains and, when missing, it can still work thanks to inside fitted batteries. Mains characteristics are: ...

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.

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.
Page 11
FAULT EXTINGUISHING PLANT OUTPUT (UNIT BLOCKED/ZONE EXCLUDED) This is a controlled output with an End-Of-Line 2,7K-1/4W resistance. This output is activated if during UDS-3 standby state an extinguishing loss condition happens, caused by manostat input activation; UDS-3 goes in “agent loss fault” and shows the “Low pressure” fault, or it is activated when the associated zone is manually excluded from the “exclusions”...

UDS-3 control panel has two analog loop inputs to manage signals dedicated to analog control panels, one loop for each zone. Each extinguishing zone is interfaced with the analog control panel through emulation with two output modules and 4 input modules (six for each zone, twelve in total for both). CNL1 terminal board is dedicated to analog loop input for zone 1 command and signals.

Buzzer acoustic signalling is activated when one of the following happens: 1. in presence of the pre-activation signal, coming from terminal board or loop, buzzer acoustic signal is silenced automatically if the pre-alarm cause is removed, bringing UDS-3 back to standby mode. 2.

KEYS DESCRIPTION Keys to use: DURING PROGRAMMING or to INSERT PASSWORD ARROWS: used for selections. ENTER: after making a selection, confirms data ESCAPE: “back”, erases the last introduced data or gets out of the menu FUNCTION KEYS: these keys activate the corresponding displayed function. These keys change in function of the selected menu.
FUNCTION KEYS Function keys allow programming menu access and status visualization for each releasing zone. They are near display’s lower border and are active during visualization of UDS-3 main screen. F1 (MENU) It allows to access main menu for UDS-3 programming and configuration. F2 (INFO) It allows accessing the visualization screen for extinguishing condition, faults, and exclusions events in zone 1.
Operating conditions Pre-activated unit condition In presence of an activation signal on one of the two inputs zone 1 and zone 2 (for control panel connection) or for pre-activation signal coming from analog loop. UDS-3 shows this condition by: active buzzer ...

Release condition UDS-3 enters this condition when it gets a signal from flowmeter input or after pre-release period (if programmed). In this state, UDS-3 activates extinguishing output and manages release cycle, checking flowmeter and manostat input. This condition is indicated by: ...
Page 19
Manual activation Analog loop activation Terminal board input activation In case of activation, extinguishing output is not operated, neither common output for release in progress condition, but only sounder output. Only whether an activation signal was present on the flowmeter input, UDS-3 gets into release status, enabling also extinguishing outputs [UNI EN 12094-1 4.15.1].

Extinguishing output activation time programming. You can set the following timings: 2 seconds 60 seconds 150 seconds 10 minutes Enabling flowmeter control (Flow ctrl.: YES) This input activation indicates that extinguishing release is in progress. If flowmeter output activates during standby condition, it means that extinguishing has not been started by UDS-3 panel but by an external device (for example a manual activation of the rapid flow valve).
Manual mode menu Selecting “Manual mode” sub-menu (with 2 level password) it’s possible to access “MANUAL” or “AUTOMATIC” modes settings for each zone. Manual mode selection makes it possible to activate extinguishing system only with a signal coming from a manual activation.
