GETTING STARTED We strongly recommend that the Noby-420 is first powered up with all 4K7 End Of Line resistors fitted at the panel as supplied by the factory. In this way you can gain confidence that the panel is operating correctly before introducing detector and sounder circuits. Power-Up With Battery • Connect two 12v SLA batteries in series (+’ve to –‘ve) to form a 24 volt battery stack, using the battery jumper link supplied. • Connect the black battery lead to the battery stack –‘ve terminal.
Power Supply Unit The Noby-420 has a 27volt regulated PSU, with a continuous current rating of 1.0A, and a 20 minute rating of 1.5A. The PSU is designed to meet the internal standby power requirements of the Noby-420 and also to charge and maintain the SLA standby battery in optimum condition. The battery standby time is dependant upon the overall system current drawn, including any ancillary equipment connected to the Aux 24v.
Inputs Zone Detector Circuits The Noby-420 requires that each detector zone is terminated with a 4K7 End Of Line resistor. This EOL resistor is necessary to facilitate open circuit, short circuit and head removal monitoring. The total current drawn by the detectors on each circuit must not exceed 2mA, which means that 20 detectors can be connected to each zone (based on a typical 100uA maximum per detector).
USER KEYPAD FUNCTIONS General Each of the following functions must be preceded by the Access Code which is fixed at [3][6][3][6]. Successful entry of the Access Code is confirmed by the red Function LED. Pressing [5] to Quit at any time will cause the system to revert back to normal standby mode, otherwise the system will automatically revert back after 10 seconds of inactivity. Mute Sounders Main external sounders switched off.
ENGINEER KEYPAD FUNCTIONS General Pressing [5] to Quit at any time will cause the system to revert back to normal standby mode, otherwise the system will automatically revert back (kickback) after approximately 10 seconds of inactivity. Sounder Fault Identification [6][2][5][3] [1][1] This function is used to identify which sounder circuit is in fault condition. The sounder circuit in fault is indicated by means of the corresponding yellow zone fault LED.
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.
Zone Faults Zone Fault LED continuously illuminated • Disconnect the relevant zone and replace with the EOL resistor (4K7) at the zone terminal. If the fault can now be cleared then there is a possible wiring error in the zone. • Check that the correct value EOL resistor is fitted at the end of the zone. • Check that the wiring and connections at each detector are consistent, and not crossed-over at any point along the cable run.
