Flex 402
Two-Zone Fire Alarm Control Panel
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
provides advanced features including
drift compensation, maintenance alert,
and freeze warning. Automatic synchro-
nization of audio/visual devices is pro-
vided, selectable for three manufactur-
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-
and four-wire smoke detectors, pull stations, waterflow devices, tamper switches
and other normally-open contact devices.

Operation
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.

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.
