1. Power On

- Lights when supply voltage is applied. This light flashes during self diagnostics start up.

2. Battery

- Lights when the BX216 is powered by a battery (optional). When flashing, the standby battery has low charge.

3. Overload Probes

- Indicates a short circuit or that one of the connected sensors is absorbing too much current.

4. Overload Battery

- Indicates that the battery supply (optional) is not properly connected or is faulty.

5. Fault

- Indicates a sensor fault, loss of signal or incorrect connection of the sensor. When on, the system will enter a full

alarm status until the faulty sensor has been removed or replaced.

6. Siren Status

- Shows green when the external siren is enabled; red when it is disabled.

7. IR Transmitter

- Can be used to transmit the contents of the internal memory to an external device.

8. Pre / Main Alarm

- Illuminate when the pre or main alarm gas threshold has been reached.

9. External Alarm

- If an externally fitted device (e.g. fire alarm or emergency stop) has activated, this LED illuminates.

10. Display

- Backlit display that shows details of the unit, connected sensors and internal programming menus.

11. Keypad

- Used to navigate through the various programming menus.

12. Printer Port

- Allows a printer to be attached to print off all the data stored in memory.

13. Test Button

- This button simulates a gas leak and tests the full funcionality of the BX216.

14. Reset Button

- When pressed it resets all internal memory.

15. Output Terminal Block

- Converts the 4 - 20mA return signal from the sensors to a 0 - 10V output connection for BMS.

16. Sensor Return Terminal Block

- Connections for the incoming return cable from the sensors.

17. Sensor Supply Terminal Block

- Connections for the outgoing power supply to the sensors.

18. Relay Terminal Block

- Connections for fault, siren, pre-alarm and main alarm relays.

19. Mains Supply Terminal Block

- Connections for the incoming mains supply.

20. External Alarm Terminal Block

- Connections for a fire alarm / external emergency stop etc.
