Install the 333 Suppressor
Use the included 333 suppressor with
the 734INT to suppress any surges
caused by energizing a magnetic lock
or door strike.
Install the 333 across the 734INT 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
Figure 7.
