Section 7: Locks and Suppression
An S-4 Suppressor Kit must be installed with every electrical switching device run
through a relay contact on the N-1000-III/IV. The Suppressor Kit protects the
N1000-III/IV from the power generated by the collapsing magnetic field of an
electrical load device.
The S-4 Suppressor Kit consists of two identical pieces. Each piece contains a
resistor, a capacitor and tranzorb network. These parts are encapsulated in a
rubber-like insulating material. One piece is installed across the relay contacts
without regard to polarity. The second is installed within 18 inches (457 mm) of
the electrical load locking device, without regard to polarity. (See Figure 7-1.)
DO NOT
run the panel wires or the lock power wires in the same cable/conduit as
the reader/communication line cables. The lock wiring should be at least 12 inches
away from the data lines, or it should have a separate conduit.
DO NOT
power door locks with the same power supply used for the N-1000-III/IV
or card readers.
