Automatic fire alarm button – reliable protection for your installation

This flush-mounted fire alarm button OP1 is a key element of a fire alarm system, designed for installation in public and industrial areas. It provides a quick and effective alarm activation in case of danger, minimizing the risk of serious consequences. Model OP1-W02-A\10-24 combines functionality, durability and ease of use.

Construction and application

Made of durable plastic, the button features a high degree of protection IP65, which guarantees its resistance to dust and moisture – an ideal solution even in harsh environmental conditions. The flush-mounted version (W02) provides an aesthetic installation, integrating with the surroundings. Equipped with an LED signaling diode powered by 24VDC, it informs about the alarm activation.

The button is available in two types of operation:

• Type A: After breaking the glass, the button is released automatically, which facilitates a quick response in a dangerous situation.
• Type B: After breaking the glass, the button must be pressed manually, which provides additional control over the alarm activation.

Thanks to the variety of available connectors (normally closed and normally open), it can be easily integrated with the existing alarm system. For example, model OP1-W02-A\10-24 has 1 normally closed connector.
