Install the 333 Suppressor
Use the included 333 suppressor with
the 734 to suppress any surges caused
by energizing a magnetic lock or door
strike.
Install the 333 across the 734 C
(common) and NO (normally open) or
NC (normally closed) terminals.
If the device being controlled by the
relay is connected to the NO and C
terminals, install the suppressor on the
NO and C terminals.
Conversely, if the device is connected to
the NC and C terminals, install the 333
Suppressor on NC and C terminals.
The suppressor wire is non‑polarized.
Install the suppressor as shown in
Figure7.
