EST4 represents a great leap forward in life safety capability, drawing on the strength and success of its predecessor – EST3 – to deliver the industry’s most robust and thoughtfully crafted networked life safety platform.

A modular panel provides extraordinary flexibility and customizable configuration, allowing you to include only the capabilities you need and to easily exclude those you don’t, while also providing future expansion capability.

EST4 adapts to a multitude of facility and campus layouts, reducing the cost of networked systems. And UL-listed proxy firewalls help protect your system against cyber threats when connecting to outside networks.

EST4's distributed audio and impressive capacity
of 100 channels per system make EST4 the clear choice to deliver critical messages when and where they are needed.

Wiring, devices, and most local EST3 rail modules are fully backwards compatible with EST4, providing easy migration paths and an economical transition to new technology.

While EST4 meets the rigorous UL864 fire alarm controls standard and UL2572 standard for mass notification today, its design is ready to adapt to future code and standard changes.

Photoelectric detectors feature advanced indirect
sensing technology for greater optical stability.

Heat detectors include three thermisters for
symmetrical thermal response.

Low profile dual sensor design — with
independent fire or CO life safety events — is
unobtrusive and eliminates the need for two
separate detectors.
