The RF280THS Series Wireless Photoelectric Smoke
Detectors include the following models:
Model RF Transmission
RF280THS 304.00 MHz
RF280ETHS 433.42 MHz
Each model is an open-area wireless smoke detector
designed for fire protective signaling and household fire
warning systems. The light emitting diode (LED) indicates
alarm, readiness, and testing. The patented chamber design
provides superior immunity to false alarms caused by dust.
The detectors have an integral 57°C (135°F) heat sensor
designed for use with household fire warning systems.
Functions
Chamber Check Self Diagnostics
The Chamber Check Self Diagnostics automatic sensitivity
test feature indicates when the detector is outside the
factory calibrated specifications. The installer can easily
determine which detectors require attention, reducing
service costs. The detector alerts users when the detector
is dirty, reducing false alarms. A unique chamber check
signal is provided.
Patented Chamber Design
The detector chamber walls and lenses optimize internal
light scattering and dust hiding capabilities. This provides
for industry leading dust immunity without sacrificing
detection. You can easily remove the detection chamber for
cleaning.
Sounder
The sounder activates on detector alarm. It is 85 dB at 3 m
(10 ft). The detector and sounder automatically reset when
the chamber clears.
Supervision Features
An internal base tamper is included. The base tamper sends
a supervisory signal every 65 minutes. The signal includes
the detector sensitivity, battery, and tamper status.
Test Features
The LED automatically flashes to indicate a calibration
trouble condition. A steady LED indicates an alarm
condition during testing. Verify sensitivity with a push
button test.
