Honeywell 5808W3 Photoelectronic Smoke And Heat Detector

New: A brand-new, unused, undamaged item in its original packaging.

The 5808W3 photoelectronic smoke/heat detector with built-in wireless transmitter is intended for use with wireless alarm systems that support 5800 series devices.
The 5808W3 smoke/ heat detector can be used with any 5800 series wireless receiver/ transceiver for residential installations. For commercial installations, the 5881ENHC or the 5883H receiver is required. The transmitter can send alarm, tamper, maintenance (when control panels are equipped to process maintenance signals), and battery condition messages to the system’s receiver. The maintenance signal fully complies with the sensitivity test requirement specified in NFPA 72, and is approved by UL.
The 5808W3 incorporates a state-of-the-art optical sensing chamber and an advanced microprocessor. The microprocessor allows the detector to automatically maintain proper operation at factory calibrated detection levels, even when sensitivity is altered due to the presence of contaminants settling into the unit’s smoke chamber. In order for this feature to work properly, the chamber must never be opened while power is applied to the smoke detector. This includes cleaning, maintenance or screen replacement. All models also feature a restorable, built-in, fixed temperature (135°F) thermal detector and is also capable of sensing a pre-freeze condition if the temperature is below 41°F.
