A-08730 Smoke Alarm
The Cleveland Controls Model A-08730 Smoke Alarm provides reliable, continuous measurement of the density of confined particulates such as dust or smoke. Calibration is automatic using front panel keys. No routine maintenance other than occasionally cleaning the lenses of the light source and receiver units is required.
The basic alarm system consists of an electronics unit and two breeching components. A light source directs a beam through the measured particulate, and a light sensor receives the beam, detects changes in opacity, and sends a proportional signal to the electronics unit. The wide-beam light source and narrow-view receiver make installation easy. Alignment of the breeching units does not need to be precise. The electronics produces a digital readout of percent opacity. SPDT contacts are provided for a remote alarm

After actuation, the alarm must be reset manually. The electronics unit is available in surface-mount and flush-mount styles. It can be installed in any dry, convenient area within 250 feet of the light source and receiver units. The face of the unit has a liquid crystal display and a “burner status” LED.

Precision. Every Day.
