Description
The Gamewell Flex 402 Fire Alarm
Control Panel brings the latest in mi-
croprocessor technology to conven-
tional fire controls. The Flex 402 is
compatible with the new i³ ™smoke
detectors from System Sensor, and
providesadvancedfeaturesincluding
driftcompensation,maintenancealert,
andfreezewarning.Automaticsynchro-
nizationofaudio/visualdevices is pro-
vided,selectable forthreemanufactur-
ers’ protocols. The NAC protocol in-
cludes 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 two-
andfour-wire smoke detectors,pullstations, waterflowdevices,tamper switches
andothernormally-opencontactdevices.
Operation
The activation of a compatible smoke detector or any normally-open fire alarm
initiatingdevicewill:activateaudibleandvisualsignalingdevices, illuminate an
indicatingLED,sound the piezo sounder at the FACP,activatethe FACPalarm
relay,and operate an optionalmodulewhichnotifies a remote station or initiates
anauxiliary 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 require-
ments 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 sensi-
tivity in terms of percent-per-foot obscuration and provides text status indica-
tion.
• The supervisory LED (per zone) provides a warning if a detector senses tem-
peratures 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 pho-
toelectronic smoke detection.
