u Modular design
u Easy detector removal for cleaning and servicing
u Stable mounting of detectors
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 for
life safety and property protection.
Functions
Indicator LED (Isolator Bases)
In the event of a short circuit, the isolator base LED
will show a steady yellow signaling a trouble condition.
Modular Design
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.
u Terminal screws for remote LED, Data In and Out
provided
u Some models include isolator circuitry which
prevents the entire SLC loop from being disabled
when a short circuit occurs
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.

Mounting Considerations
Detectors are typically mounted on the ceiling.
However, if detectors are mounted on a wall, they
must be at least 4 in. (10.2 cm), but no more than
12 in. (30.5 cm), below the ceiling. When other
devices containing magnets or producing magnetic
fields (for example, loudspeakers) are present in the
area, the base must be at least 1 ft (30 cm) from these
devices to prevent unwanted activation of the test
switch.
For UL Listing requirements, the spacing between smoke
detectors should be no more than 30 ft (9.14 m and the
spacing between heat detectors should be no more than
50 ft (15.24 m).
Wiring Considerations
The control panel communicates to the detectors via
the analog addressable loop (SLC), which allows the
use of standard non‑twisted, non‑shielded wiring.
The following wire gauges were tested and approved:
