Pyrotronics Ionization Smoke Detector DI-4A

At Life Safety Consultants, we strive to only offer high-quality products when it comes to smoke detector replacement parts. That’s why we’re proud to provide the Pyrotronics DI-4A. This detector is a plug-in, dual chamber ionization detector with adjustable sensitivity and contains two ionization chambers together with a highly sensitive semiconductor amplifier-switching circuit. One chamber detects the presence of combustion products. The second chamber serves as a reference, to stabilize the detector’s sensitivity for changes in environmental tem- perature, humidity, and pressure.  Supplies are limited on this replacement detector so order yours today and browse our website to learn more about our Cerberus Pyrotronics, and Siemens parts.
