Flex 402
Two-Zone Fire Alarm Control Panel
The Gamewell Flex 402 Fire Alarm
Control Panel brings the latest in microprocessor technology to conventional fire controls. The Flex 402 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 402 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.
• Two Style B (Class B) Initiating Device
Circuits (IDCs).
• One Style Y (Class B) Notification Appliance
Circuit (NAC).
• 24 VDC.
• 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, Wheelock,
and Gentex protocols.
– Selective Silence feature allows manual
silencing of horns while strobes continue to
flash on the same NAC.
• Silent or Audible Walk Test operation mode
commanded from the front keypad, with
automatic return to normal after one hour of
• Alarm verification selectable per zone.
• Each zone may be programmed for
supervisory or fire; each zone has separate
red and yellow LEDs.
• Disable switches provided for each zone.
• NACs programmable for: Silence Inhibit, Auto
Silence, Strobe Synchronization, Selective
Silence (horn/strobe mute), Temporal or
Steady signal, Silenceable or
• Form-C Alarm and Trouble relays.
• 3.0 amps total usable current.
• Optional dress panel (P/N DP-FLEX).
• Piezo sounder for alarm, trouble, supervisory,
and maintenance.
• Control buttons: ACK (Acknowledge), Alarm
Silence, Reset, Walktest,
Zone Enable/Disable (one per zone).
• LED indicators: Fire Alarm (one per zone),
Supervisory (one per zone), Trouble (one
per zone), Maintenance (one per zone),
AC Power, NAC Disable, Zone Disable,
NAC Fault, System Trouble, Power Trouble,
Walktest, Alarm Silence, Earth Fault (on
circuit board), Battery Fault (on circuit board),
Charger Fault (on circuit board).

Backbox Mounting
AC power, TB8
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.
