Autocall A4906-9127 is a wall-mount horn strobe with a red housing and white FIRE lettering. Its xenon strobe offers selectable intensity of 15, 30, 75 or 110 candela, and it operates on SmartSync two-wire control, so one pair of wires drives both the horn and the strobe.
On a SmartSync circuit the horn can be silenced while the strobes keep flashing. Because one model covers four intensities, installers can change the candela setting on site instead of stocking a separate device for each.
