Push button RT 45-ST-PL 30.431.54

Smoke evacuation button with acoustic signaling

This smoke evacuation button, designed for D+H 24 V DC smoke extraction systems, is a reliable solution for both installers and end-users. Its main function is to manually activate the smoke extraction system in the event of a fire, and it also provides visual and acoustic feedback on the system's operating status.

Functionality and application

The RT 45-ST-PL button displays information about the current system status – supervision, alarm or fault. The built-in acoustic signaling (75 dB) informs about system activation and any failures, which is particularly important in situations requiring a quick response. A durable, lockable housing made of die-cast aluminum provides resistance to mechanical damage and weather conditions (IP40 protection). The ability to change the labeling in 32 languages makes the button universal and can be used in various locations.

• Quick status identification: LEDs clearly indicate the system's operating status (supervision, alarm, fault).
• Clear acoustic signaling: A loud sound signal (75 dB) informs about system activation or failure.
• Durable construction: Aluminum housing protects against mechanical damage and external factors.
• Language universality: The ability to change the labeling to 32 languages makes it easier to use in an international environment.
• Easy integration: Designed to work with D+H 24 V DC smoke extraction system control panels.

Technical parameters and construction

The RT 45-ST-PL button is characterized by a solid construction and precise workmanship. The supervision current is 8 mA, and the alarm current is 20 mA. The device operates in a temperature range from -10°C to +40°C. The button dimensions are 129 x 138 x 39 mm, and its weight is only 0.31 kg, which facilitates installation. The housing color is orange (RAL ~2011), providing good visibility in various lighting conditions. The use of a modular design allows the button to be adapted to individual installation needs. It has a CNBOP certificate confirming compliance with applicable safety standards.
