FCS - Installation Manual Rev. C | 2021.12

7.3 Power Up and Warm-up

Upon power up, the FCS delays the initializing start-up sequence with a 2 minute countdown

while it waits to make sure there isn’t a power issue with the system. This process reduces

the possibility of corrupting the SD card and the conguration of the FCS if the power is

interrupted during start-up and the device is forced to reboot before initializing.

Most power issues occur and are resolved at the rst system start-up. Power issues may be

caused by events such as:

• Overloaded building mains (for the breaker)

• Incorrectly wiring the FCS LAN connections and/or analog inputs or outputs

• Connecting too many peripherals without splitting the BUS at a RPS-24VDC Remote

Power Supply

• Pulling too much power from LNK-AI devices

During the countdown, the message on the screen will display, ‘Waiting for stable power’. If

there are no power issues, after the countdown is nished, the FCS will show the initializing

screen for about four seconds of warm-up followed by a brief display of the device model

number and date/time splash screen. Then the home screen display will be shown.

NOTE: In the event the FCS shows a blank screen, power cycle the device.

After the warm up period, the system may exhibit gas alarm condition(s) if any of the sensors

have not completely stabilized during the warm up period. This is normal and the length

of time the gas alarms exist is dependent upon the length of time since the unit was last

powered up and the state of the environment it is installed in. After warm up, only the display

should be active, indicating normal operation, and the relays should be energized indicating

normal “Fail-safe” status.

7.4 Home Screen Display

There are two conguration choices for the home screen display - Summary (factory default)

or Channel.

7.4.1 Summary Display (Factory Default)

The Summary view of the home screen display shows three bars on the display. The rst is

the Channel Status bar, the second is the Relay Status bar and the third is the Peripherals or

Remote Devices Status bar.
