The SU251 is an addressable, multi input/output
device that is used to interface other fire or
security systems into the MINERVA control panel.
Inputs can be used for taking signals from other
systems (e.g. taking individual shop security
systems into the central shopping centre system)
whilst the outputs can be used to send control
signals from the MINERVA back to the individual
tenant's system. The SU521 can be configured in
one of three formats:
SU521/2 2 inputs and 2 outputs (Takes 4
addresses on the loop; max per loop is 24)
SU521/4 4 inputs and 4 outputs (Takes 8
addresses on the loop; max per loop is 12)
SU521/6 6 inputs and 6 outputs (Takes 12
addresses on the loop; max per loop is 8)
All outputs are change-over contacts rated at 24V
1A. The SU521 takes its operating power from
the MINERVA loop.
