Description 
 
Simplex fire alarm control panels maintain time and date 
for reference in the history logs. For applications where a 
master time control exists in the facility, the 4100-9816 
Master Clock Interface Module provides an interface for 
coordinating the fire alarm control panel time to that of 
the master reference. 
When time accuracy requirements include synchronization 
to GPS satellite time, the GPS/6400 Interface Module with 
the GPS-427A Antenna/Receiver can be connected to the 
model 6400 or 6351 Time Control Center. 
For additional information, refer to Installation and 
Operating Instructions 574-913.
