DC 24 V wiring to 'Fire brigade call station (AT)' PT2002-A1 or other
components
A ground fault monitor PCA2001-A1 must be used when the PT2002-A1 is
powered from a cabinet with a DC/ DC converter PCA2011-A1 or PCA2018-A1.
If the DC 24 V is used for other external components, a separate 1 A fuse is
required for each component.
A PTO2009-A1 must be used to connect the PT2002-A1 with 2 separate DC 24 V
cables from one cabinet or different cabinets. Each DC 24 V cable requires a 1 A
fuse mounted in the cabinet.
