A connected PC can access the detector event memory to review previous or current
events, such as detector alarms or faults. The detector internal chart recorder can also
be accessed to allow analysis of detector behaviour (refer to the Remote Software
Configuration User Manual
for further information). The PC cannot be used to configure
the detector except to enter time and date settings for the detector event log and chart
recorder to be viewed in the remote configuration software. The detector does not
incorporate a real-time clock, so the time and date need to be re-entered if the detector
is powered down for any reason.
Installation of the communications card also provides the detector with RS-485 network
communication via the A, B, and SCREEN terminals on the detector main board (see
Figure 9 on page 22). This can be used for simple remote display indication or
integration into a larger site wide management and display system, separate from the
local fire detection and alarm system.
