| Low-voltage wiring | Connection count needs review |
|---|---|
| Preparation | 7902 has two independent pneumatic circuits and requires a separate compressor; sequential operation is the separately selected S option. Plan supported surface mounting, access, suitable ambient location and the exact pneumatic routes before installation. Use the original control-box mounting details and the specified tubing/fittings for the selected system. Confirm compressor requirements and permitted route length for that box family; pneumatic-circuit and door-leaf quantities are not electrical cable-run quantities. Connect the selected hardwired or RF receiver actuator interface separately and test the actual control function. |
| Electrical | The box needs 120V AC at 1 amp input and an earth ground connection. It has two independent circuits that accept N.O. inputs from hardwired or RF actuator/receiver combinations. Output is 12V DC at 0.25 amp max. Conductor counts and cable runs are not established from the supplied evidence. |
| Conditional connections | 120V AC mains supply input to control box: cable runs quantity unspecified; conductor count unspecified; wire type not documented; size unspecified; shielding unspecified; rating unspecified; endpoints 120V AC supply to 7902 control box; when Installation configuration is Base 7902 control box power input, 120V AC @ 1 amp. Conductor count and cable run not documented in the supplied evidence.; Isolated SPDT relay contacts for electric strike control: cable runs quantity unspecified; conductor count unspecified; wire type not documented; size unspecified; shielding unspecified; rating unspecified; endpoints ES relay package (-3390A or -3390B) to Electric strike control circuit; when Installation configuration is Optional accessory selected: IF the ES option or an ES relay package is selected. The ES variant is separate from base 7902. The control box cannot power the strike. |
