ALARM AUXILIARY DEVICES
Control panel can drive a 24 Vcc siren via the first of the two
g
eneral alarm outputs.
Control panel constantly checks the lines inte
g
rity (a
g
ainst cuts and short circuit).
In order to obtain this function, it needs to have a siren equipped with an end-of-line resistor.
The output is protected by a 1 A fuse.
The second
g
eneral alarm output allows the user to have a volta
g
e free relais switch.
Besides, in the control panel you can find:
•1 switch control to si
g
nal GENERAL PRE-ALARM;
•1 switch control to si
g
nal the GENERAL TROUBLE;
•1 switch control to si
g
nal the ZONE 1 PRE-ALARM;
•1 switch control to si
g
nal the ZONE 2 PRE-ALARM.
All the above mentioned controls are VOLTAGE FREE and isolated from the internal circuit.

FAN CONTROLS
Control panel is able to check and drive 2 fan controls, joined respectively to zone 1 and to zone 2.
Fan lines are controlled for wire-cut, therefore relais and electro-valves used must bear a 1mA current.
As far as electro-valves or relais connection is concerned, follow the supplier’s instructions. Anyway it’s better
to use a shielded cable connectin
g
the shield to the
g
round.
For each line it’s possible to connect an electro-valve or relais 24 Vcc, max 100 mA.
Fan control lines are protected by an electronic device that, in case of persistent short, it operates limitin
g
the output current.
The line-cut is si
g
naled by special LED.
As far as INHIBITS and survey line connections is concerned, it’s better they are executed with a shielded
cable and with the shield connected to the
g
round.
»ATTENTION: not used line ALWAYS has to be closed with an 2K7, 5%, 1/4 W end-of-line resistor,
on the control panel terminal block. Otherwise you’ll receice a trouble signal for line-cut .
AUXILIARY INPUTS TO FAN CONTROLS
Inside the control panel there are also the followin
g
inputs for NORMALLY CLOSED CONTACTS, connected
to the fan control mana
g
ement:
•Input for FAN CONTROL 1 INHIBIT;
•Input for FAN CONTROL 2 INHIBIT;
•N.C. Survey line for FAN CONTROL 1;
•N.C. Survey line for FAN CONTROL 2.
»ATTENTION: not used lines ALWAYS have to be connected to ground on the control panel terminal
block. Otherwise you’ll have:
- for inhibit input = control panel behaves as the fan control is INHIBIT;
- for N.C. survey line = control panel behaves as the fan control CANNOT START.

FAN CONTROL MANAUL START INPUTS
Control panel has two manual start inputs, each associated with the relatives fan controls.
Whenoneof this buttonsis released (arenormallyclosed),therelativefancontrol starts(apart fromthecontrol
panel state of the moment).
Fan controls don’t start in the followin
g
cases:
•Inhibit input = open;
•Fan control = in trouble;
•Survey fan controls line = open;
•Battery trouble detected.
FAN CONTROL INHIBIT INPUTS
Control panel has two inhibit inputs, each associated with the relatives fan controls.
These N.C. inputs inhibit the fan control on which are joined, accordin
g
to this rule:
•Input contact closed = ENABLED line;
•Input contact open = DISABLED line.
In case of inhibit, on the control panel front, you can see the correspondin
g
LED steady on .
The led survey in real time the inhibit input state.
When there’s an alarm the control panel proceeds as above mentioned, up to the end of pre-alarm time.
At this point panel verify the inhibit input state.
When the input is enabled the relative fan control starts.
Anyway, the procedure is stopped by a SIGNAL SILENCE and /or by a ZONES RESET.
