Install the 333 Suppressor
Use the included 333 suppressor with the 734N Series module to suppress any
surges caused by energizing a magnetic lock or door strike.
Install the 333 across the module’s 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 8.
