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 Base
4098-9798, 4901-9820 Horn (set for free-run), and 4903
Series 4-wire A/V appliances horn input (not compatible
with SmartSync horn control appliances)
Compatible Simplex®equipment NAC sources:
4100ES, 4100U, or 4010ES 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
Screw terminals for wiring connections
Listed to UL Standard 864 and ULC Standard 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.
