Supressor
Use the included 333 suppressor with the 734N to suppress any surges caused by energizing a
magnetic lock or door strike.
Install the 333 across the 734N 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.
