400 Series Conventional Photoelectric Smoke Detectors

FireworX Fire & Life Safety
Conventional Initiating Devices
Standard Features
The GE FX7 Series conventional self-diagnostic, smoke detectors,
with CleanMe® continually monitor their own sensitivity and operational status, and provide a trouble condition at the FireworX conventional control panel and FX detector if they drift out of sensitivity
range or fail internal diagnostics. This meets NPFA 72 field sensitivity requirements without the need for external meters.
• Self-diagnostics continuously monitor operational status
Additional diagnostic information is activated by applying a magnet
near the detector’s integral reed switch. This initiates a self-diagnostic routine and provides visual indication of sensitivity level, or if
service is required.
• Advanced false alarm immunity
If the 400 Series ever does require cleaning simply replace GE’s
patented field-replaceable optical chamber. All models are designed
to reduce false alarms from dust, insects, RFI and external light.
• Optional features include:
- Integral 85dB temporal sounder
- Auxiliary Relay
- Built-in Power Supervision Relay
- Integral fixed/Rate-of-Rise heat detector
- Isolated fixed/Rate-of-Rise heat detector
- 2 and 4 wire models
- Wide 2 wire compatibility listing
An integral combination rate-of-rise and fixed 135°F (57°C),50-foot
rated, heat sensor is available with all “T” model detectors (see
selection guide). An integrated silicon heat sensor and a dedicated
microprocessor are used to detect heat and perform the rate of rise
calculations, for earlier heat detection.
• Field-replaceable optical chamber
• CleanMe smoke detector maintenance reporting between conventional FX7 Seres and FireworX FACP's
• Low-profile design
• Models to meet most any application
• Backwards compatible with ESL 400 Series Smoke Detectors
The 400 Series models allow latching of the alarm for either smoke
or heat. The 449CSRH includes an isolated alarm output for heat
and activates an internal non-latching sounder (local alarm) for
smoke, making it ideal for motel/hotel and dormitory rooms
where smoking is permitted.

Engineering Specification
F 503-691-7566
The GE 400 Series low-profile, self-diagnostic, smoke detectors work on the light scattering
principle. A pulsed infrared lightemitting diode serves as the light source, and a high-speed
photo-diode as the sensing element. When the amount of light reflected onto the photodiode reaches the sensitivity setting, the smoke sampling rate increases. Three (3) successive
smoke sensings above the sensitivity setting are required to sound an alarm. This design
has superior protection against false alarms caused by dust, insects,
RF and ambient-light.

A confirmed alarm causes the normally flashing power indicator LED to light continuously
and the optional alarm relay (available in “R” models) to operate. A trouble indication is
automatically displayed by flashing the LED every second. An internal 85 dB horn (available
in “S” models) emits a temporal tone when the detector alarms or when power polarity is
reversed. The proprietary optical sensing chamber is field replaceable, allowing quick and
easy cleaning and maintenance.
Models with auxiliary relays are approved for releasing service. The low profile 400 Series
detectors are equipped with a hinged cover, a concealed tamper-resistant latch, and insect
screens. All wiring terminates in plug-in, clamp-type screw terminals. The detectors mount
to a standard single-gang electrical box, a four inch octagonal, four-inch square electrical
box, or WIREMOLD No. 5739 fixture box.
