DF6000 - USER MANUAL

Input/Outputs

Panel Inputs

Class Change: (option not required by EN54)

A pair of terminals are provided for class change. By shorting these terminals together (e.g. switch, time

clock) the alarm will sound (panel sounders + loop sounders only). The panel will not indicate a ﬁre. The

alarm will cancel when the short circuit is removed. If the short circuit is not removed the alarms will not

cancel.

WARNING: No voltage should be applied to this input

Panel Outputs

Panel Sounders: (option 7.8 EN54 Pt 2)

Two pairs of outputs are provided. ONLY polarised equipment should be used. Ensure the polarity of the

connections are observed at all times and end of line resistors (6k8 5%) are ﬁtted for correct operation.

The total alarm load across all sounder outputs = 1.5 Amp all outputs are fused with 1.6 Amp glass fuse

alarm devices should be spread equally across the 4 sounder circuits.

WARNING: Do not exceed the rated output current

Output Fire Alarm Routing Equipment

(option 7.9 EN54 Pt 2)

This output, which is fused and monitored using a 6.8k end of line resistor, is used for the automatic

transmission of the ﬁre signals to ﬁre alarm routing equipment (e.g. ﬁre brigade). It operates by providing

12 V output to an auxiliary device (e.g. relay). It is current limited to 30 mA using a resettable polyswitch.

Class change and test conditions do not operate this output. If operated under a ﬁre alarm condition, the

indication will be displayed on the touch screen display and will remain until the ﬁre alarm is reset. Ensure

the polarity of the connections are observed at all times and end of line resistors (6k8 5%) are ﬁtted for

correct operation.
