u Contacts are rated 2 A at 24 VDC

u Flexible application and quick response to

emergency conditions

u Can be alarmed or reset by zone or by individual

address

The modules provide a supervised polarity reversal
output used for audible and visual signaling devices or
to trigger a remote NAC power expander. They require
a 24 VDC auxiliary input voltage that can be provided
by the FPA‑1000 Analog Addressable Fire Panels or
other UL listed power supplies.
The modules provide a Class B Circuit rated for 2 A at
24 VDC. They fit into a standard 4‑inch square or
double‑gang electrical back box.

Functions

Evacuation Tones

The following programmable patterns are selectable:

• Steady

• Pulsing

• Temporal 3

Flexibility

The operating parameters for the modules are saved at
the integrated EEPROM and maintained by the module
so that during emergency situations no communication
with the fire panel is needed which provides flexibility
and quick response to emergency conditions. The fire
panel only broadcasts system conditions on the
Signaling Line Circuit (SLC) and each module
processes them according to its configuration.

Analog Device Programmer

u Bi‑colored LED provides module status

Status display

A bi‑colored LED flashes every time the module is
polled and can be switched on steady when the
module goes into active condition.

Short Circuit Isolation

Built‑in short circuit isolating (SCI) circuitry that, in
the event of a short circuit on the SLC line, will
prevent entire loop failure and send a short circuit
condition report to the FACP, and, upon removal of
the short circuit condition, automatically restore the
entire loop to normal operation.
