Noby-420 Installation & Programming Instructions Rev3 Page 7 of 12
Configure Fault_Input Polarity [6][2][5][3] [2][4] [1]
This option configures the Fault_Input signal to be normally high, going low to initiate a fault condition.
Key [1] to Toggle the option - the Common Fault LED indicates the current option status.
Key [4] to Accept and update the configuration option to E2PROM . . . OR
Key [5] to Quit and revert back to normal standby mode without updating the E2PROM.
The factory default is with the option disabled i.e. the Fault_Input is normally low, going high to initiate a fault
condition.
ENGINEER PROGRAMMING - System Options 2
The following options allow various monitoring functions to be disabled, and are intended to make the Noby-420
backwards compatible with detectors and sounders that may be encountered in older installation sites. With each
of the following options the corresponding status LED indicates that the monitoring is disabled when the status
LED is ON.
Detector Head Removal Monitor Inhibit
[3] [3] [5] [1] [4] [2] [6] [3] [1]
This option disables the head removal monitoring.
Key [1] to Toggle the option - the Zone-1 fault LED indicates the current option status.
Key [4] to Accept and update the configuration option to E2PROM - then revert back to normal standby mode..OR
Key [5] to Quit and revert back to normal standby mode without updating the E2PROM.
Zone Short Circuit Fault Monitor Inhibit
[3] [3] [5] [1] [4] [2] [6] [3] [2]
This option disables zone short-circuit monitoring and forces s/c’s to be detected as a fire condition.
Key [2] to Toggle the option - the Zone-2 fault LED indicates the current option status.
Key [4] to Accept and update the configuration option to E2PROM - then revert back to normal standby mode..OR
Key [5] to Quit and revert back to normal standby mode without updating the E2PROM.
Battery Condition Monitor Inhibit
[3] [3] [5] [1] [4] [2] [6] [3] [3]
This option disables the battery capacity and battery fuse monitoring.
Key [3] to Toggle the option - the Isolate LED indicates the current option status.
Key [4] to Accept and update the configuration option to E2PROM - then revert back to normal standby mode..OR
Key [5] to Quit and revert back to normal standby mode without updating the E2PROM.
Sounder Circuit Fault Monitor Inhibit
[3] [3] [5] [1] [4] [2] [6] [3] [6]
This option disables the sounder circuit fault monitoring.
Key [6] to Toggle the option - the Test LED indicates the current option status.
Key [4] to Accept and update the configuration option to E2PROM - then revert back to normal standby mode..OR
Key [5] to Quit and revert back to normal standby mode without updating the E2PROM.
TROUBLESHOOTING
Power Supply
The Power LED not illuminated
• Check that the mains supply is connected and switched on.
• Check the mains supply fuse in the terminal block adjacent to the transformer.
• Check the transformer secondary fuse F5 on the main board.
PSU Fault LED continuously illuminated
• The panel is detecting low voltage (< 21V) from the batteries.
• Check the batteries are connected correctly, in series, and observing strict polarity.
• The batteries may be heavily discharged – allow approx. 1hr for a partial re-charge.
The PSU Fault LED will flash when the battery voltage increases to 23V.
The PSU Fault will clear when the panel is reset.
• The batteries may be faulty – replace as necessary.
PSU Fault LED flashing
• Check the batteries are connected correctly, in series, and observing strict polarity.
• Check Fuse F4 (Battery).
• Check Fuse F1 (Aux 24V).
