The FAA-440 Analog Bases come in two sizes (4 in. [10 cm] and 6 in. [16 cm]) and two models (Standard and ISO which has a built-in isolator). They are used in
combination with FAP-440 and FAH-440 analog addressable detectors to provide early fire warning forlife safety and property protection.
Indicator LED (Isolator Bases)
In the event of a short circuit, the isolator base LED will show a steady yellow signaling a trouble condition.
The detector base is part of a two-piece modular designed detector assembly. The permanently installed base provides in and out terminals 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.
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.
