Manual fire alarm – reliable protection for your installation

The OP1 manual fire alarm is a key element of the fire alarm system, designed for quick and effective alerting in the event of a threat. Model OP1-W02-B\11, in a flush-mounted version, integrates perfectly with the building's architecture, providing a discreet yet easily accessible alarm activation point. The device is made of durable plastic, which guarantees its durability and resistance to mechanical damage.

Construction and operating principle

The OP1 fire alarm button is designed with simplicity of operation and reliability in mind. The flush-mounted version (W02) requires embedding in the wall, which ensures an aesthetic appearance and protection against accidental damage. After breaking the glass (type B), it is necessary to manually press the button, which initiates the alarm signal. The glass is a replaceable element, allowing for quick restoration of full functionality after the alarm. The device has an IP65 protection rating, which means it is resistant to dust and water jets – an ideal solution for both industrial and public facilities. Additionally, the presence of protective glass prevents accidental triggering of the alarm.

Application and compatibility

The OP1 alarm is widely used in public buildings, industrial plants and anywhere where reliable fire detection is required. It is compatible with various alarm systems and can be equipped with additional signaling elements (e.g. LED lamp). Thanks to the possibility of configuring the current loops (normally open NO/normally closed NC and mixed NC/NO), it can be easily integrated with the existing electrical infrastructure of the building. For example: NO circuits open after breaking the glass or removing the cover, and NC circuits close in the same situation. In the case of type B – after breaking the glass, the button must be pressed manually to change the state of the circuits. The device meets the requirements of the PN-EN 54-11 standard and has appropriate approval certificates (No. 2266/2014 and EC No. 1438/CPD/0130), which confirms its high quality and safety of use. The cross-section of the connecting wires is 2x 1...2.5 mm² (solid) or 2x 0.75...1.5 mm² (stranded).
