The FW-SMK as a part of the FREEWAVE wireless security system is
an advanced, fully supervised SMOKE DETECTOR transmitter.
The FW-SMK is photoelectric smoke detector designed to sense smoke, but not gas, heat nor flame. It provides early warning of developing fire by sounding an alarm w ith its built-in alarm horn, and by transmitting a coded alarm signal to a receiver. The FW-SMK is powered by an internal, long life 9 Volt A lkaline or Lithium battery.
Each FW-SMK has an unique ID code (24bit). Compatible FreeWave receivers are designed to “learn” the specific ID
of FW-SMK detectors and respond only to them. Alarm and other data are forwarded to the control panel for specific event indication.
A periodic test transmission for supervision purposes takes place automatically once in 18 min ~ 19 min.
The receiver is informed that the FW-SMK detector is taking an active part in the wireless security system.
It must be borne in mind, though, that effective pre-warning of fire accidents is only possible if the detector is located, installed and
maintained properly as described in this manual.
This smoke detector is designed for use in a single
residential unit only, which means that it should be used inside a single
family home or apartment. It is not meant to be used in lobbies,
hallways, basements or another apartment in multi-family buildings,
unless they’re already working detectors in each family unit. Smoke
detectors, placed in common areas outside the individual living unit,
such as on porches or in hallways, may not provide early warning to residents. In multi-family buildings, each family living unit should set up its own detector.
This detector is not meant to be used in non-residential
buildings. Warehouses, industrial or commercial buildings, special
purpose non-residential buildings require special fire detection and
alarm systems. This detector alone is not a suitable substitute for

alarm will turn itself off when the smoke is gone. If nuisance alarms
persist, attempt to clean the detector as described in this manual.
WARNING: Do not stand close to the detector when the alarm is
sounding. The alarm is loud in order to wake you in an emergency. Too
