5808W3 Photoelectronic Smoke/Heat Detector


Honeywell's 5808W3 is a 3V lithium powered, photo-electronic smoke/heat detector with a built-in wireless transmitter. It is intended for use with any 5800 Series Wireless Receiver/Transmitter for residential installations (for commercial installations, the 5881ENHC or the 5883H receiver is required). 

The transmitter can send alarm ,tamper, maintenance (when control panes are equipped to process maintenance signals), and battery condition messages to the system's receiver. Smoothing algorithms minimize nuisance alarms by soothing out  short term spikes from dust and smoke - virtually eliminating nuisance alarms.

Since there are no holes to drill or wires to run, you can preserve the beauty of the building while protecting it. The 5808W3 is an ideal  detector for those difficult to wire locations, applications where a room aesthetics are critical, or where hazardous materials exist.

All models also feature a restorable, built-in, fixed temperature (135 F) thermal detector that is also capable of sensing a pre-freeze condition if the temperature is below 41 F.


  • The distance between the detector and receiver has been significantly increased without a repeater                      

  • Mathematical calculations in the detector's software minimize nuisance alarms by smoothing out short term spikes from dust and smoke

  • A signal is sent to the control panel when the detector requires cleaning. This allows a regular, non-emergency service call to clean the detector before it goes into alarm

  • Virtually eliminates nuisance alarms from long-term dust build-up by automatically adjusting the detector's sensitivity

  • The technician is able to quickly and easily clean the detector chamber without disassembling the detector head

  • UL listings for both residential and commercial applications are met

  • Identifying between alarm or trouble conditions is a snap with green and red status indicators

  • The sturdy mounting base allows the detector to be easily installed on uneven surfaces. (i.e. stucco).
