| Preparation | The 918 mounts to a single gang box (Standard) or to a narrow-stile door frame (Narrow). A surface-mount single gang box (9SURBOX) is listed as an accessory. The box depth and cutout dimensions are not documented in the supplied text. |
| Electrical | For the selected 916 or 918, choose the actual MO momentary, MA maintained or TD timer version. The manufacturer table lists one SPST normally-open and one SPST normally-closed contact for MO/MA, rated 6A@24V. The TD version uses DPDT timer contacts rated 5A@24V and the timer is mounted separately. The rear view identifies 23/24 as normally open and 11/12 as normally closed. These are contact functions and load ratings, not a required supply or a universal field conductor count. Select the used contact circuit and actual timer arrangement before cable specification and run quantities. |
