The Signal Combination Duo LED is designed
for use in general industrial applications and may be used indoors or outdoors. The signalling device is suitable for
ceiling or wall mounting as long as the position will not allow for dust or water to settle in the bell mouth. The
device is a very compact unit incorporating power supply, strobe light, amplifier and loudspeaker. The loudspeaker is
made of impact and weather-resistant plastic and is mounted rigidly on the housing. The cap of the strobe light forms
the housing cover and is made of polycarbonate.
