OT302
The ORENA OT302 is a 2-wire, non-polarity conventional photoelectric smoke detector operating at 24VDC, featuring a high-sensitivity optical chamber for detecting smoldering fires with low false alarm rates.
Designed without base for flexible mounting options, it connects directly to conventional fire panels and uses advanced light-scattering technology with insect-resistant mesh for reliable performance in various environments.
