2.3.2 - Outputs on CNO terminal block
General fault output
Uncontrolled relay output with NO-NC changeover contact selectable via jumper (J2).
This output signals the presence of any "fault condition".
Output not suitable for connection of a fault-transmitting device.
Release in progress
Uncontrolled relay output with NO-NC changeover contact selectable via jumper (J3).
This output is active as soon as the UDS-4N enters the "release condition" and will remain active until the reset
command is executed.
Output not suitable for connection of an alarm transmission device.
Emergency extension output active
Uncontrolled relay output with NO-NC changeover contact selectable via jumper (J4).
This output is activated as soon as the UDS-4N enters the "emergency prolongation condition" and remains active
until the "emergency prolongation" input returns to the normal condition.
Manual-only shutdown output active
Uncontrolled relay output with NO-NC changeover contact selectable via jumper (J5).
This output is activated when the UDS-4N enters the "manual only mode condition".
Emergency stop output activated
Uncontrolled relay output with NO-NC changeover contact selectable via jumper (J6).
This output is activated when the UDS-4N enters the 'emergency shutdown condition' .
Discharged output
Uncontrolled relay output with NO-NC selection via (J1).
This output is activated at the end of the shutdown cycle only if the release is successful (pressure switch and/or flow
switch input active) and indicates that the extinguishing agent has been discharged.
3 - INTERFACE TO THE ANALOGUE PANELS
The UDS-4N has an analogue loop input for analogue control panel signalling. The extinguishing zone to the analogue
fire panel is emulated with 2 output modules and 4 input modules. The CNL terminal block is dedicated to the analogue
loop input for commands and signalling.
3.1 - Functional description of analogue modules
– 2 output modules (in the fire panel to be programmed as TYPE-ID = UDS1).
These outputs for the fire panel are inputs for the UDS-4N and are dedicated to the activation of the extinguishing
cycle. Like the conventional inputs (ALL1 and ALL2), when both are activated (CMX/1 and CMX/2), they allow
the UDS-4N to be placed in the activated condition.
A fault on conventional inputs does not block the functionality of these inputs.
– 4 MMX/1÷4 input modules (in the fire alarm control panel programmed as TYPE-ID = UDS2) for signalling
faults of the UDS-4N to the analogue control panel.
N.B: these six modules have consecutive addresses and only the following addresses are possible:
– 10-15, 20-25, 30-35, ..., 90-95, for CLIP module emulation;
– 10-15, ..., 90-95, 100-105, 110-15, ..., 150-155, for ADVANCED module emulation.
