SLC Circuits
The MA-1000 Panel comes with two SLCs (one loop card) which have the following
parameters:
Supply voltage: 24VDC
Addressable Loops
Max Number: 2
Max Loop Load per loop: 60 mA
Max Number of Addressable Devices per loop: 200
Loop lengths: The maximum permitted loop length is 2 km measured from the near to
the far terminals.
The total number of addresses per loop is 200; this includes detectors, manual pulls and
all other addressable items. When designing systems it
’
s recommended that
allowances are made for future expansion, Short circuit isolators are incorporated into
every MA-1000 loop device, including Smoke detectors, heat detectors, manual pulls
and interfaces. Therefore, no further fault protection is required, in the event of a single
fault; none of the devices connected to the loop will fail to operate as the fault will be
isolated by the two adjacent devices.
