Model: 4904-9139

Operating Voltage: 20-31 VDC

Strobe Intensity: 15 cd

Notes: Label notes a strobe flash rate of 1 Hz (one flash per second), but when the proper voltage is applied, the flash rate is actually a bit faster (approx 1.5hz). It is also somewhat rare to see this style strobe in a public building, as it is usually made to be attached to a retrofit plate (model 4905-9921) as seen in pictures 6 and 7.
