Table 1: Unit options

Mechanical Installation

The unit consists of two parts. The front panel and a backplate. The backplate can be mounted on

a wall or console. The connector on the back of the unit will protrude though the backplate into

the wall.

A ridge on the top of the unit holds the front panel in place. The front panel can be fastened using

a screw on the bottom of the unit.

Figure 1: Mounting options

Optionally, a wall mount box (P/N: 96016) can be provided to mount the unit on a wall without

needing a hole. This box provides space for the cabling.

Connecting Sensors

Figure 3: Zone schematic

Power supply

The FBD-2 has a main and backup power supply input. A fault will be indicated on the front and

the fault output will be activated when one of the supplies fails. If only one supply is needed, the

main and backup supplies must be connected together to avoid generating a fault.

Zones

Unit has two zones. The zone output provides the sensor loop with 24V DC regardless of the

voltage supplied on the supply inputs. An End of Line resistor (EOL) of 5.6kΩshould be placed at

the end of the loop as show in Figure 3. Placing it at any other point will prevent open loop

detection from working properly. If a zone is unused the EOL resistor should still be connected.

Key Switch Input

A key switch can be added to only allow authorised personnel to accept a fire alarm. The switch

should be in the closed position when the key is turned. When no key switch is used this input

should be bridged.

Fault Output

Used with Vessel’s Monitoring System, contact factory for more information.

Alarm Output

Used with Vessel’s Monitoring System, contact factory for more information.

Buzzer Output

A buzzer can be connected to the buzzer contact. This is a potential free contact that closes when

a fire occurs. The voltage for the buzzer needs to be supplied externally.

2. Configuring the FBD-2 Fire alarm panel

Short Circuit as Alarm

Some older non EN54 or BS5839 compliant systems do not use internal resistors. These systems

cause a short on the zone loop when a fire is detected. When such a system is used, the alarm

panel needs to be set to “short circuit as fire” via the jumper on the back. A short on the line will

now cause a fire alarm as a result, not a fault. Note that an actual short in the wiring can no longer

be detected and will also cause a fire alarm. The panel is set to “short circuit as fire” When the top

two pins are bridged using the jumper. When the bottom two pins are bridged, the panel is set to

“short circuit as fault”. The jumper should be placed as shown in Figure 4.

Note: Changing the jumper requires a restart to take effect

3. User Manual

The FBD-2 fire alarm panel provides fire detection and alarm functionality.

Operation

The unit is always operational when powered. During normal operation the “OK”LED should be

on to indicate the zone is working properly.

The “FAULT”LED will blink, and an audible alarm will be generated when a fault is detected on a

zone. There are two fault situations:

Short:

There is a short in the zone cabling. The FBD-2 removes the power from the zone and indicates a

fault situation. When the “SILENCE” button is pressed the alarm will be muted, the “FAULT”LED

will light up without blinking and the “OK”LED will blink for one minute. After a minute the zone

will turn back on. A new fault will be generated if the short persists. A fault will not be generated

when the unit is configured for “short circuit as alarm”, a fire alarm will be generated instead.

Note that when a key switch is present, the alarm can only be accepted when the key is turned to

the closed position.

Open Circuit:

The EOL resistor is no longer detected. This indicates there is a break in the zone loop. When the

“SILENCE” button is pressed the alarm will be muted and the “FAULT”LED will light up without

blinking. When the EOL resistor is detected the “OK”LED will turn on and the zone will be

operational again once the “SILENCE” button has been pressed again.

Silence Button

Pressing the “SILENCE” button will accept and mute alarms, fire alarms can only be accepted if the

key is in the closed position or bridged.

When a fire is detected the “FIRE” LED will light up and an audible alarm will be generated. If the

fire alarm is accepted but still active after 2 minutes, the alarm will return.

Dimming Button

The front LEDs can be dimmed to preserve night vision. Press and hold the “DIM” button until the

LEDs reach the desired brightness. The “FAULT”and “FIRE”LEDs will not be dimmed for safety.

Test Button

The “TEST” button can be pressed to test the LEDs. Pressing the “TEST” button for 30 seconds will

also activate the buzzer and alarm and fault outputs.

Power LED

The “POWER” LED blinks green while the unit is in operation normally. If one of the power

supplies fails, the “POWER” LED will light up red.

4. Maintenance

The FBD-2 unit is maintenance free. It is permitted to clean the front of the FBD-2 unit with a

damp cloth.

5. Troubleshooting

Symptom

Possible Cause

Test and Remedies

Green LED is not flashing

Power supply is not connected

Check if power supply is

connected

Green LED light up without

flashing

Micro controller is in error.

Power the unit off and on

A fault is generated when a

manual call point is pressed

A shorting call point is used

The jumper should be set to

“short circuit as fire”

A short causes a fire alarm

instead of a fault

The unit is setup for shorting

call points

The jumper should be set to

“short circuit as fault”

Alarm or fault cannot be

accepted

The key switch contacts are not

bridged

The key is not in de closed

position or if the key is not

installed bridge the key switch
