X7
For connection of smoke detector type WSA 300.
Data
7.1 +
7.2 -
Imax = 3,4mA
For connection of a different type smoke detector, see above.
When no smoke detector is connected to X7, a 10kΩ resistor is connected to the input.
X8
24/48V input from e.g. Fire Alarm System (used
primarily in France).
Data
8.1 +
8.2 -
Active at voltages between 18 and 50V
Passive below 1V
Max.50V
This input is only active when DIP switch 1.7 is ON,
see section 11.
When this input is in use, break glass units cannot
be connected to the panel.
Connection example
X9
Solid state outputs, one solid state output for transmission of fault signal to Fire Alarm System and 2 outputs
indicating alarm in the smoke zones.
Data
9.1 Fault – Open contact = Fault, closed contact = OK
9.2 Fault – Open contact = Fault, closed contact = OK
9.3 Output A, smoke zone 1 alarm – Open contact = normal, closed contact = Alarm
9.4 Output A, smoke zone 1 alarm – Open contact = normal, closed contact = Alarm
9.5 Output B, smoke zone 2 alarm – Open contact = normal, closed contact = Alarm
9.6 Output B, smoke zone 2 alarm – Open contact = normal, closed contact = Alarm
Solid state output for transmission of fault signal to Fire Alarm System.
A fault must last a minium of 20 seconds befoe the relay indicate a fault.
Data
Max voltage: 30 Vp (peak)
Max output: 150 mA
Typical On-resistance: 4,7 Ω
Max On-resistance: 8 Ω
Max switching speed: 2 ms
