Flex 404
Four-Zone Fire Alarm Control Panel
The Gamewell Flex 404 Fire Alarm
Control Panel brings the latest in microprocessor technology to conventional fire controls. The Flex 404 is
compatible with the new i³ ™ smoke
detectors from System Sensor, and
provides advanced features including
drift compensation, maintenance alert,
and freeze warning. Automatic synchronization of audio/visual devices is
provided, selectable for three manufacturers’ protocols. The NAC protocol includes the ability, using a single pair
of wires, to silence audible devices
while strobes continue to flash.
The Flex 404 is also compatible with conventional input devices such as twoand four-wire smoke detectors, pull stations, waterflow devices, tamper switches
and other normally-open contact devices.
The activation of a compatible smoke detector or any normally-open fire alarm
initiating device will: activate audible and visual signaling devices, illuminate an
indicating LED, sound the piezo sounder at the FACP, activate the FACP alarm
relay, and operate an optional module which notifies a remote station or initiates
an auxiliary control function.
i³™ Technology Features
• Drift compensation automatically adjusts detector sensitivity and increases
resistance to false alarms caused by dust accumulation.
• The maintenance alert LEDs (per zone) warn of excessive dirt accumulation,
preventing false alarms.
• Detector sensitivity is automatically measured. The twice-yearly test requirements of NFPA 72 (7-3.2.1) are met without using a ladder or test meter.
• The wireless handheld sensitivity meter eliminates the need for voltmeters,
magnets, or a physical connection to the detector. The reader displays sensitivity in terms of percent-per-foot obscuration and provides text status indication.
• The supervisory LED (per zone) provides a warning if a detector senses temperatures approaching freezing.
• Special test protocol and LED indication allow a quick test of all detectors —
without a ladder.
• Electronic heat-sensing element provides thermal detection in addition to photoelectronic smoke detection.

• NAC synchronization features:
– Provides synchronization of standard ANSI
audible signals as required by NFPA 72
– Provides synchronization of ADA compliant
strobes per NFPA 72 (4-4.4.1).
– Selectable for System Sensor, CooperWheelock,& Gentex protocols.
– Selective Silence feature allows manual
silencing of horns while strobes continue to
flash on the same NAC.

commanded from the front keypad, with
automatic return to normal after one hour of

Backbox Mounting
The cabinet can be surface-mounted. The door is removable during installation
by opening and lifting it off the hinges. The cabinet mounts using two key slots at
the top of the backbox and two additional 0.250" diameter holes at the bottom.
