The GE Interlogix FP400 Series are conventional microprocessor-controlled fire detection and alarm panels, available in models such as the FP416 and FP404. These panels are designed to provide quick and efficient reaction in case of fire or fault situations by constantly checking connected devices and providing warning signals.
Function Description:
The FP400 Series panels monitor fire detection zones for alarms and faults. When an alarm situation is detected, the panel activates visual and acoustic indicators, including a general Fire LED and a zone-specific Fire LED, and triggers internal buzzers and alarm relays. If a sounder delay is programmed, the sounders will activate after the specified delay. In a fault situation, the panel indicates the type and location of the fault through flashing general fault, zone fault, power fault, or sounder fault LEDs, an intermittent internal buzzer, and activation of the fault relay.
The panel supports various operating modes:
- Standby: The system is powered up, indicated by the Supply ON LED. If a sounder delay is programmed, the Sounder Delay LED is also active. No acoustic signals are present.
- Alarm: Triggered by a detector or manual call point. The general Fire LED and the specific zone Fire LED are activated. A flashing LED indicates a detector alarm, while a constant LED indicates a manual call point alarm. The internal buzzer sounds continuously, and alarm relays and sounders (with programmed delay) are activated.
- Fault: Detected when there's an issue with a zone, power supply, or sounder. Indicated by flashing general fault, zone fault, power fault, or sounder fault LEDs, an intermittent internal buzzer, and activation of the fault relay.
- Disabled Status: Allows individual zones to be enabled or disabled. When a zone is disabled, it will not report any events or indications to the panel. This is indicated by intermittent general Disable and/or continuous zone Disable LEDs, and an intermittent internal buzzer.
- Zone Test Status: Allows testing of individual zones. Activated by pressing the Test button along with the desired Zone button. The panel activates corresponding outputs for 3 seconds and then automatically resets. Indicated by a steady general Test LED and the Fault LED of the zone in test. No acoustic signal is present, but sounders can be activated without delay during test mode.
- Out of Service: Occurs when mains power is lost and battery voltage drops below 22 V. In this mode, there are no alarm or fault warnings. Indicated by flashing general fault and steady Out of Service LEDs, an intermittent acoustic indicator, and activation of the fault relay.
Important Technical Specifications:
- Battery Voltage: Minimum working voltage is 22 VDC. The panel enters "Out of Service" mode if battery voltage drops below this. All operations stop if battery voltage reaches 19 V.
- Power Supply: Operates on 110 or 230 VAC.
- End-of-Line Resistor: Requires a 4k7 end-of-line resistor for zones.
- Battery Charger Voltage: 27.6 VDC.
- Detector Compatibility: Supports Clean-Me enabled detectors for maintenance indications.
Usage Features:
The control panel features a set of LED indicators and buttons for operation:
LED Indicators:
- Fire (zone) (1): Red LED. Flashing for detector alarm, constant for manual call point alarm.
- Fault / Test / Disabled (zone) (2): Yellow LED. Flashing for zone fault, constant for disabled or test mode.
- Supply ON (3): Green LED, indicates system is powered.
- Fire (general) (4): Red LED. Flashing for detector alarm, constant for manual call point alarm.
- Fault (general) (5): Flashing yellow LED for fire system fault.
- Disabled (6): Indicates a disabled zone or sounder.
- Maintenance (7): Yellow LED for Clean-Me enabled detectors, indicates maintenance required. Zone displayed when Silence Buzzer key is pressed for >1 second (standby mode only).
- Sounder Delay (8): Indicates a programmed sounder delay.
- Sounder Fault / Disabled (9): Flashing yellow for sounder output fault, constant for disabled sounders.
- System Fault (10): Indicates a fault in the fire panel.
- Supply Fault (11): Indicates power supply fault (mains, batteries, or fuse).
- Out of Service (12): Indicates loss of power and battery voltage below 22 VDC.
- Silence Buzzer (13): Indicates the fire panel buzzer has been silenced.
- Sounders ON (14): Indicates sounders are activated. Flashing if sounders will activate after programmed delay.
- Sounders Silence (15): Indicates sounders have been silenced.
- Test (16): Indicates a zone is in test mode.
Acoustic Indicators:
- Alarm: Continuous internal buzzer.
- Fault: Intermittent internal buzzer.
- A. Zone (Z1, Z2 etc.): Enables/disables a zone. LED is ON when disabled.
- B. Silence Buzzer: Silences the internal buzzer and activates its corresponding LED.
- C. Reset: Restarts the system. Unresolved faults/alarms will be re-highlighted. Requires the control panel key to be in the ON position to reset.
- D. Sounder ON: Activates sounder outputs. Can disable a programmed delay from level 1.
- E. Sounders Silence / Disable: Stops active sounder outputs and activates its LED. Can disable inactive sounders by pressing for ~2 seconds. Press again to enable.
- F. Test: Tests internal buzzer and unit LEDs. Pressing with a zone button puts the zone into test mode.
- G. ON/OFF (key): Enables and disables the keyboard.
Fire Panel Operation in Alarm State:
- Silence Internal Buzzer: Press the Silence Buzzer button.
- Silence Sounders: Press the Silence Sounders button. To re-activate, push the Sound Alarm button. To activate sounders without delay (from security level 1), keep the Sound Alarm button pressed for 4 seconds.
- Reset System: Press the Reset button. Not recommended until the cause of the alarm is resolved.
Fire Panel Operation in Fault State:
- Silence Internal Buzzer: Press the Silence Buzzer button.
- Restart System: Press the Reset button.
Fire Panel Operation During Disabled Status:
- Silence Internal Buzzer: Press the Silence Buzzer button.
- Restart System: Press the Reset button.
Fire Panel Operation In/Out-of-Service:
- Silence Internal Buzzer: Press the Silence Buzzer button.
- If the panel enters this mode, it is recommended to disconnect the system until mains power is restored to prevent battery damage.
Maintenance Features:
To ensure correct functioning and EN-54 compliance, regular checks are recommended:
- Daily Verification: Check if the system is in ready status. Address any incidents or alerts.
- Weekly Verification: Test at least one detector or call point to confirm panel function (vary the device tested).
- Quarterly Verification: Performed by fire system experts. Test one device per zone, supervise output activation, and verify batteries and load voltage.
- Annual Verification: All system devices must be checked.
- Battery Maintenance: Batteries should be replaced periodically, typically every 4 years. Avoid total discharge.
- Cleaning: Keep the panel's exterior and interior clean. Use a damp cloth for the outside; avoid solvents. Do not use liquid products inside the panel.
- Record Keeping: Maintain a register book for all system incidents (fire alarms, faults, modifications).
Troubleshooting:
The manual provides a troubleshooting guide to address common issues based on LED indications and buzzer sounds:
- Service LED OFF: Panel has no power.
- Action: Check power supply (110 or 230 VAC), power supply fuse, battery, battery fuse.
- General fault and power supply failure LED ON, buzzer intermittent: Panel running on batteries due to no mains power.
- Action: Check power supply (110 or 230 VAC), power supply fuse, transformer, battery connection, battery fuse. Verify battery voltage > 24 VDC and charger voltage is 27.6 VDC.
- System failure LED ON, buzzer continuous: Control panel failure.

- General fault and zone failure LED (flashing) ON, buzzer intermittent: Indicated zone has a fault.
- Action: Check end-of-line resistance (4k7), short/open circuits, inverted polarity detector connections, and manual call points without series resistance.
- General disabled and zone disabled LED ON, buzzer intermittent: Indicated zone is disabled.
- Action: Turn key to ON, press disabled zone key to enable.
- Panel does not respond to keypad: Keypad is disabled.
