Bosch RFSM
Bosch RFSM RADION wireless smoke detector
- Externally visible LED that indicates smoke detector status
- A built-in sounder for alarm alerts
- Supervised for low-battery, tamper, and removal from mounting surface tamper conditions
- Operational up to 5 years using two user replaceable CR123A Lithium batteries
RADION smoke is a photoelectric (RFSM-A version alsoRADION smoke is a photoelectric (RFSM-A version alsoincludes “dual fixed/rate-of-rise on” functionality)wireless detector that transmits alarm signals to thewireless receiver when smoke is detected.
Alarm ModeAlarm ModeThe detector’s built-in 85 dBA sounder initiates analarm signal and an RF signal indicating the alarmcondition is sent when the detector goes into alarmmode. The receiver signals the control panelidentifying the specific detector in alarm. Alarmconditions are non-latching so if the alarm conditiongoes away (smoke dissipates), the detector returns toa normal state.
The photoelectric smoke detector continuously acquires ambient obscuration data as it monitors the surrounding environment. The red LED blinks every time a sample is taken. If any one sample is above the calibrated alarm threshold, two more samples are taken at 4 second intervals. If all three samples are above the calibrated alarm threshold, the detector goes into alarm mode.
Status indicator
The LED and sounder indicate the status of the detector but not of the RF signaling circuitry. Under normal conditions, the red LED flashes regulary while the sensor monitors the surrounding environment.
When the sensor detects smoke, the LED changes from flashing to steady ON and the sounder produces a loud, continuous tone.
Test Silence button operation
A Test Silence button allows for performance of the sounder and sensitivity tests and silencing of alarm sounder and trouble chirp.
Drift compensation
The detector has built-in drift compensation that allows the alarm to adjust sensitivity automatically as it becomes dirty over time. The drift compensation feature dramatically increases the time between cleanings, as well as reducing the chance of a nuisance alarm.
