4.1.3 D1257 Remote Fire Annunciator
The D1257 Remote Fire Annunciator (Figure 11)
displays system information. It can be mounted in areas
of public access because it does not provide system
control. It displays text identifying specific initiating
and supervisory devices.
Do not mount command centers or
annunciators where they will be exposed to
sunlight. Sunlight can damage internal
components and interfere with display
visibility. Do not mount command centers or
annunciators in wet or moist locations.
There is a maximum number of command
centers. You can connect up to eight
supervised or 32 unsupervised command
centers to the D9124 system. The available
power, number of supervised command
centers, and number of areas you intend to
use affect the total number of command
centers you can connect to the D9124
system.
