Quest 261 Area Sound Level Detector

Signal devices typically used include buzzers, lights, sirens or indictors such as the Quest Model LB-26 Light Box. However, any electrical device that uses up to 10 amps and 300 V DC or AC can be used.

The Model 261, along with the LB-26 Light Box, is especially useful in monitoring the exceedance of maximum exposure limits defined by regulatory agencies, corporate standards or community ordinances.

The 261 accepts up to three microphones to monitor a specific area. The standard microphone cable is 30 ft. (9.14 m) long, however it can be extended to 80 ft. (24.4 m) with an optional cable.

The threshold noise level is easily adjustable from 55 to 110 dB in 0.5 dB increments on the panel of the Detector/Controller. The reaction time – the interval between the time when the threshold is exceeded and the time when the warning circuit is activated – is also adjustable.
