Possible Cause

The wiring is open at some point in the installation. There is no physical return to the Draco panel in installations configured as Class A (closed loop).Poor contact or faulty connection of a short-circuit isolator at its base.

Recommended Solution

1. If the installation is designed as a loop (Class A), physically check that the return cable is correctly connected to the relevant terminals on the panel.
2. Check that all JBE-2150 loop isolator modules are firmly seated in their sockets.
3. To isolate the cut section, temporarily change the configuration to Class B (no return) in the settings menu and check the signal report to see which devices stop responding, in order to locate the cut point.

Possible Cause

A device has been connected to the loop but has not been registered in the panel’s logical configuration.

Recommended Solution

1. Recommended option: Go to the INSTALL menu and perform an Auto-Register devices so that the control panel automatically recognises and integrates the new equipment into the database.
2. Manual option: Go to the ADJUST menu -> 1. Manual device registration and de-register and manually enter the exact loop, address and device type. Once you have finished, reset the system.

Possible Cause

The control panel is not receiving power

Recommended Solution

1. Check that 230 VAC mains voltage is present at the installation input.
2. Check the control panel's mains fuse (250 VAC - 4A).
3.  Check that the batteries are properly connected and that the battery fuse (2A) is not blown.

Possible Cause

There is a physical fault on the detection line of the affected zone  

Recommended Solution

1. Using a multimeter, check that the end-of-line resistor at the end of the zone is exactly 4.7 kΩ.
2. Check for short circuits or open circuits in the zone wiring.
3. Make sure that no detectors are installed with reversed polarity in their bases.
4. Check whether any manual call point has been activated and does not have an internal alarm resistor.

The JBE-2200 conventional zone module uses a dedicated orange FAULT LED to indicate faults through different flashing patterns:

• LED Steady ON: Open Circuit. The supervised 4.7 kΩ end-of-line resistor is not installed, is damaged, or the conventional zone line is open at some point.
• 1 Flash per Second: Low Voltage. The conventional zone line supply voltage is insufficient to ensure proper operation.
• 2 Flashes per Second: Short Circuit. A resistance close to 0 Ω has been detected, or a conventional detector or manual call point is incorrectly connected to the line.
• Continuous Rapid Flashing: Overcurrent. Too many conventional detectors are installed on the conventional zone, exceeding the maximum current load permitted by the module.
• 3-Second Flashing: Reset Process. Indicates that the module is performing a zone reset and temporarily disconnecting power from the conventional detectors to reset them.

• Cause: Reversed power supply polarity or voltage outside the permitted range.
• Solution: Check that the power supply wiring is connected to the fire alarm control panel's 24V Aux output, with the correct polarity, and that the voltage is within the range of 5 VDC to 30 VDC.

• Cause: Incorrect APN, username, or password settings for the SIM card operator.
• Solution: Access the transmitter configuration and check that the APN, Username, and Password parameters exactly match those provided by the mobile network operator. The use of dedicated M2M SIM cards with a flat-rate data plan of at least 1 GB/month is recommended.
  

The Draco control panel has restricted access security levels to prevent unauthorized operation:

• Level 1 (Public/Firefighters): No password is required. Allows the internal buzzer to be silenced and basic status reports to be viewed.
• Level 2 (Authorized User): The factory default password is 111 (3 digits). Provides access to reset functions, zone tests, indicator tests, keypad tests, and device or zone disablement.
• Level 3 (Installer/Maintenance): The factory default password is 1111111111 (10 ones). Provides access to advanced system configuration, device-to-zone assignment, cause-and-effect logic for outputs, and delay settings.
• Display update note: The code used to access the firmware update screen via the USB port is 111111111 (10 ones).

The addressable detection loop of the Draco control panel supports a maximum cable distance of up to 2,000 metres. The manufacturer requires the use of 2 x 1.5 mm² twisted-pair cable without shielding. The JBE intelligent bus is non-polarized for field devices, which greatly simplifies installation and prevents faults caused by reversed cable connections on the loop.​

Each addressable loop of the Draco control panel supports a maximum of 200 logical addresses (which may include detectors, manual call points, input or output modules, and addressable sounders). A single Draco control panel can be expanded using JBE-P2L2-2LP loop expansion cards up to a maximum of 8 loops, allowing a total maximum of 1,600 addressable devices per control panel.

After confirming that the alarm condition has ended and that there is no actual danger:

1. Unlock the keypad: Insert the physical key into the control panel's front key switch or enter the Level 2 password.
2. Silence the buzzer and sounders: Press the Panel Silence button to silence the internal buzzer and Sounders Silence or Sounders OFF/ON on the panel.
3. Perform the reset: Press the RESET button. This temporarily cuts power to the loop for approximately 9 seconds to reset the automatic detectors and return the system to its normal standby condition.
