fuse and reverse polarity. The box has space for 2 x 12 Vdc 7 Ah. The connection is made
as shown in Figure 8.
2. Auxiliary 30 Vdc output.
30 Vdc auxiliary output with a maximum capacity of 1 A. It allows feeding other devices as
sounders (see Figure 7). This output is protected by a self-resetting fuse and performs
supervision of tension, consumption and cross line.
Figure 5).
3. Fault.
Fault dry contact output not supervised with capacity of 1 A (30 Vdc - 230 Vac). It is only
active on the card C1 (See Figure 5). It will be triggered when a fault occurs in the system or
there is not power in the system (the common contact-Normally Open (NO) relay is shorted
indicating fault). Only disabled when there is no fault in the system and the control panel is
electrically fed (Common-contact Normally Open (NO) relay is electrically open).
4. Alarm.
Dry contact output with common contact (C) Normally open (NO), and capacity of 1 A (30
Vdc - 230 Vac). Corresponds to the alarm output in zone 1, 2, 3 or 4 depending on the
position on the card, and the card in the box (see Figure 5).
It is activated when the measured concentration for any sensor of the zone communicates
instantaneous concentration values equal or higher than alarm level, for longer time than the
delay activation of alarm. It is deactivated when the above instantaneous concentration is
lower than the alarm level, for longer time than the delay to stop of alarm.
5. Ventilation 1.
Dry contact output with common contact (C) Normally open (NO), and capacity of 1 A (30
Vdc - 230 Vac). It corresponds to the ventilation zone 1, 2, 3 or 4 depending on the position
on the card, and the card in the box (see Figure 5).
It is activated when the sensor with the highest average concentration of the zone is higher
than the ventilation level 1, for longer time than the delay to activation of ventilation 1.
It is deactivated when the previous average concentration is lower than the ventilation level
1, for longer time than the delay to stop of ventilation 1.
In the event that an alarm occurs, it will also activate the ventilation 1 of that zone. In this
case, for stopping ventilation 1 of this zone it will have to wait for turning off the alarm and
the concentration of ventilation 1 be under ventilation level 1 higher time than the delay to
stop of ventilation 1.
