Central Display Unit and Horn Strobe for Gas Safety Alarms
Couldn't load pickup availability
The Central Display Unit (CDU-HS1) for Gas Safety Alarms with Horn Strobe is designed to provide real-time visibility of CO2 or O2 levels, alarms, and historical trends; enabling users to respond quickly to a potential gas hazard all from a single centralized display unit.
The CDU also serves as a critical source in ensuring compliance with industry regulations (OSHA/NIOSH/NBIC) by displaying the necessary data from the gas detection alarms across multiple locations from one dashboard.
When paired with the RAD-0102-6-HS2 or RAD-0002-ZR-HS2, the CDU acts as the command hub, consolidating real-time gas readings and relaying critical alerts to safety personnel.
To get started, ensure you have a proper RAD-0102-6 or RAD-0002-ZR to integrate or contact a sales specialist who can help you with a custom system for your application.
