Auxiliary Output
The Auxiliary Output is a 30V dc output provided at the panel
to power ancillary equipment (Figure 8). The current consumed
by this output must be considered when calculating battery
standby times. The contacts are not monitored.
Class Change
The sounders can be operated by an external volt free
contact (Figure 9). A short circuit at this terminal will activate
non-latching sounders (no indication will show on the fire
alarm panel). The sounders will automatically silence when the
short circuit is removed. This is sometimes used for schools at
class change times.
