OPERATION
EMERGENCY
1. Signal from smoke detector part No. 36418Q
This emergency is relevant to the presence of
smoke.
The smoke detector memorizes any active alarm
until it is disconnected from its base or the reset
button is pressed on the emergency push-button (if
present) or the reset inside the control unit.
This alarm state sends the opening command, the
red led of the emergency push button (if present)
and of the control unit switches on, and the siren
output is activated for as long as the alarm state
remains active.
2.
Pressing emergency button (N.C. button)
part No. 40564B
To activate the emergency opening control, press
the button on the emergency push-button; the red
led of the emergency push-button and of the
control unit switches on, and the siren output is
activated as long as the alarm state remains active.
The state of emergency can be deactivated any
time by pressing the reset button on the push-
button or inside the control unit.
The presence of the emergency push-button is
recommended to activate manually the emergency
opening control and to display the
anomaly/emergency and RESET signals.
N.B.: in case of alarm all manual controls
are disabled.
MANUAL CONTROLS
For the manual control, 2 inputs are provided for
standard buttons (
part No. 40050U
or others),
each of which controls an actuator output.
The control unit receives the impulse command
and maintains it for 3 minutes to allow every
actuator to reach the limit stop.
The control can be stopped using the following
ways:
a) after reaching the maximum travel time of 3
minutes
b) pressing the reset key (the device stops)
c) pressing and quickly releasing the relevant
control key (the device stops)
When the actuator is stopped, to select the new
direction of travel, press and release the button
relevant to the new action desired.
N.B.:
-
in case of alarm, all the manual controls are
disabled.
-
in case of voltage supply failure, only 1
closing control will be allowed (to avoid the
consumption of the batteries and to close the
windows waiting for the main power to
return).
ANOMALIES
Anomalies are signalled on the control unit
(through the transparent cap) and on the
emergency push-button (here the led blinks) by the
lighting of a yellow led.
Anomalies can be the followings:
- interruption of the smoke detectors electric wire
- interruption and short-circuit of the actuators
electric wire
-
flat or low batteries (every 6 hours an automatic
check up is provided)
SIGNALS
Visual signals are provided thruogh leds inside the
control unit and on the emergency push-button, as
well as emergency acoustic signals through the
self-fed external siren (
part No. 40892C
or
similar) connected to the SIREN/RELAY output.
The leds inside the control unit are evident through
the transparent cap on the cover.
Green led on:
it indicates the voltage supply is on
Yellow led on (blinking on the pushbutton
panel)
: it indicates one of the above anomalies is
present
Red led on:
it indicates an alarm is active
In a normal operating condition, if
voltage supply is provided and no alarms
or anomalies are present, only the green
led should be lit.
Siren:
the self-fed siren, connected to the
SIREN/RELAY output, is activated by the
presence
of an alarm.
