TRANSMITTERS
**************************************************************************
NOTE: State the make and model number of existing
proprietary supervising station receiving equipment.
The choice of code transmitter, or radio transmitter
depends upon the type of existing fire reporting
system at the activity. When telegraphic systems
exist, use code transmitter. Determine the type of
activity reporting system (i.e., positive non
interfering or shunt). In most cases a local
energy-tripping device will be required.
The facility Fire Dept. or Engineering office should
be contacted to determine the type and amount of
data to be supervised (monitored), i.e. -type:
separate or common transmission of alarm,
supervisory, and trouble type signals; -amount: all
points, all zones, or the combined premises. Verify
that existing monitoring equipment has sufficient
capacity to support the additional premises or that
it can be expanded as necessary to accommodate the
new fire alarm system. Identify existing components.
