Setting up extinguishing monitoring circuit
The extinguishing output circuit is factory set to monitor the end of line diode that is fitted to the terminals
and will normally show a value of around 270.
If the parameters of the Extinguishing output change e.g. by connecting a solenoid in parallel with the
monitoring diode or removing the diode and fitting igniting actuators, then the extinguishing output
monitoring level will need to be "learnt". See section 14.16 for details. To do this, operate the ENABLE
CONTROLS keyswitch to put the system into access level 2.
The LCD will show:
Operate the WRITE ENABLE switch by gently sliding it to the right. The LCD will show:
Press the ENTER button and then the UP button repeatedly until the LCD displays:
The XXX displayed here is the previous (factory level) to which the monitoring level had been sent.
Press the ENTER button. The LCD will now show:
The XXX shown here is the current monitoring level detected on the extinguishing input. Press the
ENTER button to learn the new monitoring level.
Press the UP button to set the monitoring level for output 2 in the same way if it is being used, otherwise
switch the WRITE ENABLE slide switch to the left and check that an open or short circuit fault on the
extinguishing output(s) is detected and shown on the control panel.
10 Aux 24V DC supply output
The terminals for the Aux 24V supply are labelled Aux 24V + and ROV. The ROV terminal is the negative
terminal.
It is possible to have the Aux24V supply outputs removed for a few seconds when the panel is reset.
Aux 24V not removed upon reset is set as default on the ECU. To change this, switch the system to
access level 2 by operating the ENABLE CONTROL keyswitch and then operate the WRITE ENABLE
switch by gently sliding it to the left.
The LCD will show:
Press the ENTER button and then the UP repeatedly until the LCD displays:
