Manual fire alarm – reliable protection for your installation

This surface-mounted device, known as the fire alarm button OP1, is a key element of the fire alarm system. Designed for both commercial and industrial applications, it provides quick and effective notification of a hazard. The construction with red plastic and IP65 protection guarantees durability and resistance to environmental conditions. The included hammer facilitates quick activation of the alarm in emergency situations.

Functionality and application

The OP1-W01-B\11-24-m is a type B manual fire alarm, which means that after breaking the glass, it is necessary to additionally press the button to activate the alarm. It has one normally open (NO) and one normally closed (NC) contact, allowing for flexible adaptation to different installation configurations. A 24VDC LED indicator provides visual confirmation of alarm activation. The device complies with the PN-EN 54-11 standard, which confirms its high quality and reliability.

• Wide range of applications: ideal for offices, warehouses, production halls, schools and other public facilities.
• Easy installation: surface-mounted version allows for quick and easy installation without the need to interfere with the building structure.
• Durable construction: plastic housing and IP65 protection ensure resistance to mechanical damage and weathering.
• Visual signaling: 24VDC LED informs about the alarm activation, which increases awareness of the hazard.
• Protection against accidental activation: type B requires pressing the button after breaking the glass, minimizing the risk of false alarms.
• Compatibility with alarm systems: possibility to connect to various fire alarm systems thanks to different contact configurations (NO/NC).
