FAA 325 B4 4 inch Analog Sensor Base

www.boschsecurity.com

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.

uModular design

uSmall and robust detector base with same diameter as detectors

uEasy detector removal for cleaning and servicing

uStable fixing of detectors

uTerminal screws for remote LED, Data In and Out provided
