The IQ621 is a professional-grade, UL-listed addressable manual pull station designed for intelligent fire alarm systems. Compliant with UL 38 standards for Fire Protective Signalling Systems, it meets ADA requirements with a maximum 5 lb activation force — ensuring accessibility and regulatory compliance across commercial, institutional, and public-use buildings.

Smart Activation, Instant Confirmation
To trigger an alarm, simply lift the front cover and press the button. A red LED illuminates immediately upon activation to provide clear visual confirmation. A reset key is included with every unit for quick and easy service restoration.

Addressable & Flexible
Unlike conventional pull stations, the IQ621 integrates directly into addressable fire alarm loops, enabling precise location identification at the control panel. It also features a normally closed or normally open dry contact, offering added flexibility for integration with third-party systems.

Built to Last
Crafted from durable materials with solid construction, the IQ621 is engineered for reliable, long-term performance in demanding environments.
