Features
Provides Temporal Code 4 (TC4) NAC
(Notification Appliance Circuit) control for
Carbon Monoxide (CO) gas warning:
•The TC4 CO gas warning is a repeated sequence of
four cycles of 100 msec on with 100 msec off,
followed by 5 seconds off per NFPA 720, Standard
for the Installation of Carbon Monoxide (CO)
Warning Equipment in Dwelling Units
•Compatible appliances includes: CO Sounder Bases
4098-9771 and 4098-9798, 4901-9820 Horn (set for
free-run), 49CMT Series multi-tone horns (set for
free-run horn tones), and 4903 Series 4-wire A/V
appliances horn input (not compatible with SmartSync
horn control appliances)
Compatible equipment NAC sources:
•AUTOPULSE Z20
•Simplex 4007ES Hybrid, 4010ES, 4100ES, and
4100U NAC outputs
•4009 IDNet NAC Extender NAC outputs
•Each module requires an input NAC that powers the
3A rated output NAC for control of compatible
audible notification appliances only (not for strobes)
Three selectable operation modes:
•Synchronized operation allows a separate and
dedicated control NAC to both activate and
synchronize the Temporal Code 4 output timing of up
to 20, 4905-9835 modules
•Unsynchronized operation also allows the separate
and dedicated control NAC to activate the Temporal
Code 4 output timing of up to 20, 4905-9835 modules,
but without synchronization between the modules
•Stand-Alone operation allows the input NAC in
alarm to activate Temporal Code 4 timing for NACs
dedicated for CO gas alarm; no fire alarm signals are
available, no control NAC is used
•For both Synchronized and Unsynchronized modes,
when the control NAC is off, the module output NACs
will follow the fire alarm signals of the input NAC
•NOTE: For TC4 output, both the input NACs and the
control NACs requires a Steady On signal
Compact, sealed construction:
•Mounts in standard 4” square electrical box
•Compatible with Adapter Plate 4090-9813 to fit
4 11⁄16” (119 mm) square electrical boxes
•Screw terminals for wiring connections
Listed to UL 864 and ULC S527
Description
CO gas alarm warnings are required to be different from
fire alarm warnings. In the event of a CO gas alarm, the
presence of a Temporal Code 4 audible signal pattern
identifies the type of condition to the responders to assist in
determining the proper actions to be taken.
4905-9835 Temporal Code 4 Module
(shown approximately 1/2 size)
Description (Continued)
CO gas alarm, or fire alarm. Use of the 4905-9835
Temporal Code 4 Module allows the NFPA 720 Temporal
Code 4 signal to be generated using a standard Steady On
audible appliance NAC input. Under the fire alarm panel’s
control, the audible notification signal can be selected for a
conventional fire pulse pattern for a fire alarm condition, or
the Temporal Code 4 pattern can be activated for a CO gas
alarm condition.
