supervision

The AL802‑WAL NAC Power Extender is a
cost‑effective 8 A remote power supply and battery
charger that can be connected to any 12 VDC or
24 VDC fire alarm control panel (FACP). Its primary
application is to provide notification appliance circuit
(NAC) expansion support that meets Americans with
Disabilities Act (ADA) requirements. It can also be
used to provide auxiliary power to support system
accessories.

Functions

Battery Backup

There is a built‑in charger for sealed lead‑acid or
gel‑type batteries. The enclosure has room for two
12 VDC, 12 Ah batteries. If AC fails, there is automatic
switchover (with zero voltage drop on switchover) to
standby battery.

Inputs

Power input is 115 VAC, 60 Hz, 1.45 A. There are two
normally‑closed (NC) dry contact trigger inputs. The
unit is equipped for two Class A or two Class B FACP
inputs.

u LEDs indicate prior fault on one or more signaling

circuit outputs

u One auxiliary power output (1 A supply current)

with battery backup

NAC Loop Supervision

In non‑alarm conditions, independent loop supervision
for Class A and/or Class B FACP NACs is provided. In
the event of a loop trouble, the FACP is notified by the
steered input (input 1 or input 2). In addition, there
are common trouble output terminals (NC, C, NO) that
are used to indicate general loop or system trouble. A
common trouble input is provided for optional
normally‑closed (NC) devices to report trouble to the
FACP. Two FACP signaling outputs can be employed
and directed to control supervision and power delivery
to any combination of the four outputs. The unit also
has Loop Output trouble memory indication to help
identify troublesome sporadic problems.

Outputs

The AL802‑WAL delivers electronically regulated and
filtered 12 V or 24 V power to Class B or Class A NAC
loop circuits. Additionally, a separate 1.0 A auxiliary
output for four‑wire smoke detectors is available. The
8 A maximum alarm current can be divided among the
four outputs for powering NAC devices. Each output is
rated at 2.5 A maximum. The outputs are Class 2 rated
power limited outputs with auto reset thermal and
short-circuit protection.

Output Programming

Each output can be independently programmed for
Steady, Temporal Code 3, or Strobe synchronization.
All outputs can be programmed for Input to Output
Follower mode.

Paralleling Outputs

An individual output of 4 A can be obtained by
paralleling two outputs.

Horn and Strobe Synchronization

The two-wire synchronization mode works with the
Gentex Commander GOS Sync Mode 3, 4 and ST/HS
series, the System Sensor SpectrAlert series of horns,
strobes, and horn strobe combinations, and Cooper
Wheelock horns, strobes, and horn strobe
combinations to provide a means of synchronizing the
temporal-coded horns, synchronizing the flash timing
of the strobe, and silencing the horns of the horn
strobe combination over a two-wire circuit while
leaving the strobes active.

Notice

The AL802‑WAL will synchronize only the horns,
horn strobes and strobes that contain
synchronization capability.
