Detector fault, DXX lost comms
The system believes it has lost connection to a detector on address XX, verify detector addresses and press the “learn
button”
(16)
. Verify all connected detectors are being registered by pressing “blind button B” (see page 2). If you have no
detectors connected to the system pressing the learn button will clear the error message.
Gas Off, Switch On Fan X.
The system can monitor the fan status via a current monitor or air pressure switches. These provide a closed contact to
terminals Fan A and Fan B, it is a requirement when using fan interlocking that the fans be running (and therefore the A and B1
receiving a closed contact) before the system can begin a gas pressure test. If at any point the fans stop running (opening the A
or B contact) the system will isolate the gas and report fans not running. Check that the fans are not only switched on, but
actually running and moving air.
Gas Off, Reset Em Stops & Switch On/Off
The system has an panel mounted emergency stop and connection inside for remote buttons. First check the panel button (once
pressed some require resetting by twisting and releasing). Clear the message by turning the main system switch off and then
back on, if the message remains check any remote buttons and their connections. The terminal for the remote buttons requires
a volt free normally closed contact, ensure all remote stop buttons, thermal links any another connected systems (BMS/Fire
panels) are reset and the contacts are closed.
In the event of any alert the system will always give a reason on screen as to the cause.
