Automatic fire button OP1 surface mounted 1 NC 1 NO + signaling LED 24VDC OP1-W01-A\11-24

Fire alarm button – quick reaction in emergency situations

This surface-mounted OP1 fire alarm button is a reliable element of the fire alarm system, designed for wall mounting. Its red plastic housing provides high visibility, and the IP65 protection rating guarantees resistance to dust and water jets, making it an ideal solution for both indoor and outdoor use. Model OP1-W01-A\11-24 is equipped with one normally open and one normally closed contact, as well as a signaling LED powered by 24VDC.

Construction and operating principle

The button is designed in accordance with the PN-EN 54-11 standard, which confirms its compliance with European safety standards. Version "A" means that after breaking the glass, the button is automatically released – physical damage to the cover is sufficient to activate the alarm. This minimizes the reaction time in a dangerous situation. Protective glass prevents accidental triggering of the alarm while allowing for quick action in the event of a real threat.

Application and benefits

The OP1 button is used in various industrial and public facilities where reliable fire signaling is required. Its versatility makes it a popular choice among alarm system installers and building owners who care about safety.

• Fast reaction: Automatic button release after breaking the glass shortens the alarm activation time.
• Resistance to external conditions: IP65 protection rating ensures reliable operation even in harsh environmental conditions.
• Versatility: Can be used in various types of facilities – from warehouses to offices and public buildings.
• Clear signaling: The LED facilitates visual identification of the alarm status.

Technical data in practice

The button measures 113 x 113 x 52 mm, making it easy to integrate into the existing building infrastructure. Made of durable plastic, it is resistant to mechanical damage and corrosion. Connection cables with a cross-section of 1...2.5 mm² (solid core) or 0.75...1.5 mm² (stranded) ensure a stable electrical connection. The rated insulation voltage is 500V, and the rated continuous current is 10A – these parameters guarantee safe and reliable operation of the device in the alarm system.
