Terminal box

1. Zone outputs:

Outputs of control panel for connection of detection zones.
It supplies, 24 Vdc aprox, in standby condition. With End Of Line resistance of 4K7, it
supply 22 Vdc aprox. With detectors and wire, in standby condition, the voltage must
not be under 19 Vdc aprox.
When voltage is higher than 22,6 Vdc aprox, Control panel indicates open line.
In detector alarm status, the detector forces voltage line in a range of 8 to 15 Vdc. For
Manual Call Point alarm status, Manual call point force voltage in a range from 3 to 8
Vdc. Under 3 Vdc, Control Panel indicates crossed line.
Open line, detector alarm and manual call point thresholds can be modified using the
CPU microswitches (see chapter 7.3).
2. Sounder output:
Control Panel has 2 sounder outputs monitored and independent with simultaneous
activation protected by a fuse. In this way, in case of fault in one output, the other can
still be operated by the control panel.
The outputs are activated simultaneously when an alarm occurs in the system and the
programmed delay time is passed. It will disable when there is no alarm in the system.
It is possible to lock it (see control key 5).
In standby condition, the output delivers -14 Vdc aprox, and in active condition +29 Vdc
aprox.
3. Alarm output:
Dry contact output not monitored.
In Alarm status, contacts Common- Normally Open (NO) of the relay are shorted. In
any other status, contacts Common- Normally Closed (NC) of the relay are shorted.
4. Fault output:
Dry contact output not monitored.
In Fault status or Control Panel not electrically supplied, Common- Normally Open (NO)
contacts are shorted meaning FAULT. With Control Panel electrically supplied and with
not any fault, Common- Normally Open (NO) contacts are electrically Open.
5. Auxiliary Output of 30V:
Output of 30V monitored and protected by a fuse, which powers sounders,
electromagnets of fire doors, etc.
NOTE: Monitoring of this output is only for crossed line.
6. Batteries output:
The batteries output, monitored and protected by a fuse, allows the batteries to be
connected to the control panel.
Through this connection, batteries are charged and their condition monitored.
This output is protected against reverse polarity.
