u Modular design

u Small and robust detector base with same diameter

as detectors

u Easy detector removal for cleaning and servicing

The FAA‑325‑B4 Analog Detector Base is combined
with analog addressable detectors that use an
advanced digital communication protocol to provide
early fire warning for life safety and property
protection.

Functions

Modular Design

The detector base is part of a two-piece modular
designed detector assembly. The permanently
installed base provides in and out connection points
for the polling circuit.

Preservation of loop

It contains a simple rugged design with terminal
screws for wiring and preserves loop continuity when
detectors are removed.

Locking System

A simple tamper‑proof locking system is provided
which can be enabled by removing a small plastic tab
on the back of the detector. Once locked, the detector
can only be removed by using a small screw driver.

u Stable fixing of detectors

u Terminal screws for remote LED, Data In and Out

provided
