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.
CNL2 terminal board is dedicated to analog loop input for zone 2 command and signals.
N.B. CNL1 and CNL2 terminal boards must not be connected on the same analog loop, as indicated
by 1294-1
Analog mode operation

2 output modules for each zone (to set as TYPE-ID = UDS1).
These two alarms are in OR with conventional inputs (respectively: CMX/1=ALL1 and CMX/2=ALL2).
Damages on conventional input don't block these alarms.

4 input modules for each zone (to set as TYPE-ID = UDS2) for UDS-3 faults signalling to analog
control panel.
N.B. these six modules have consecutive addresses and only the following are allowed: 10-15,
20-25, 30-35, etc till 90-95.
Faults are sent towards analog control panel this way:

1st CMX signals (only if 3rd MMX is excluded) a fault (open circuit) when the control panel is
DISABLED or in MANUAL mode.

2nd CMX signals (only if 4th MMX is excluded) a fault (open circuit) for mains 230Vac missing or for
out of range power (voltage must be between 21-29Vdc).

1st MMX signals a fault (open circuit) in case of general fault of UDS-3

2nd MMX signals a fault (open circuit) in case of extinguishing line fault.

3rd MMX signals a fault (open circuit) when DISABLED or in MANUAL mode.

4th MMX signals a fault (open circuit) for mains 230Vac missing or for out of range power (voltage
must be between 21-29Vdc).

3rd and 4th MMX signals are also sent to CMX modules (1, 2) when two MMX modules (3, 4) are
excluded.

Commands
EVACUATION: Sounder activation output for each extinguishing zone.
Getting into this function through level 2 password, it allows selecting the zone to alarm
EXCLUSION
Allows exclusions setting through level 2 password.
Getting into this function, before entering into exclusions specific screen, it allows selecting zone (zone 1 or
zone 2).
A single exclusion presence, brings the relating zone into "out of service" condition
BUZZER SILENCING
It allows silencing UDS-3 buzzer.
