APPLICATIONS
Example 1: Expand notification appliance power an addi-
tional 6.0 amps (FCPS-24S6) or 8.0 amps (FCPS-24S8). Use
up to four Class B (Style Y) outputs or four Class A (Style Z)
outputs (using ZNAC-4). For example, the FACP notification
appliance circuits will activate the FCPS when reverse-polar-
ity activation occurs. Trouble conditions on the FCPS are
sensed by the FACP through the notification appliance circuit.
Example 2: Use the FCPS to expand auxiliary regulated
24-volt system power up to 4.0 amps (FCPS-24S6) or up to
6.0 amps (FCPS-24S8). Both resettable and non-resettable
power options are available. Resettable outputs are created
by connecting the resettable output from the FACP to one or
both of the FCPS inputs.
Example 3: Use addressable control modules to activate
the FCPS instead of activating it through the FACP notification
appliance circuits. This typically allows for mounting the FCPS
at greater distances* away from the FACP while expanding
system architecture in various applications.
For example, an addressable control module is used to acti-
vate the FCPS, and an addressable monitor module is used to
sense FCPS trouble conditions. Local auxiliary power output from
the FCPS provides power to the
addressable control module.
*Addressable FACPs are capable
of locating control and monitor
modules at distances of up to
10,000 feet (3048 meters).
AGENCY LISTINGS
AND APPROVALS
See the first page of this data
sheet for listing agencies and file
numbers. These listings and ap-
provals apply to the FCPS-24S6
and the FCPS-24S8. In some
cases, certain modules or appli-
cations may not be listed by cer-
tain approval agencies, or listing
may be in process. Consult fac-
tory for latest listing status.
SYNC FOLLOWER/GENERATOR NOTE
In some installations, it is necessary to synchronize the flash
timing of all strobes in the system for ADA compliance. Strobes
accomplish this by monitoring very short timing pulses on the
NAC power which are created by the FACP. When installed at
the end of a NAC wire run, the FCPS-24S6/-24S8 can track
(i.e., “follow”) the strobe synchronization timing pulses on the
existing NAC wire run. This maintains the overall system flash
timing of the additional strobes attached to the FCPS.
When the FCPS-24S6/-24S8 is configured (via DIP switch set-
tings) as a “sync follower,” the FCPS’s NAC outputs track the
strobe synchronization pulses present at the FCPS’s sync in-
put terminal. The pulses originate from an upstream FACP or
other power supply.
When the FCPS-24S6/-24S8 is configured (via DIP switch set-
tings) as a “sync generator,” the FCPS’s sync input terminals
are not used. Rather, the FCPS is the originator of the strobe
synchronization pulses on the FCPS’s NAC outputs. In “sync
generator” mode, the sync type (System Sensor, Wheelock,
or Gentex) is selectable via DIP switch settings.
