3.2. BOLT THROUGH DOOR PREPARATION:
Figure 1 illustrates a section view of the through door mount (on a solid wood door). This
configuration may be used on solid wood doors, hollow or solid metal doors, or chalk filled *fire
doors.
*Note: The Dual Sense Bar may not be used on a fire rated door that requires a fire
rated latch! The DSB has no latch. Occasionally however, fire doors are permitted on
openings where a fire rated barrier is not required. Use of the DSB should always be
verified and approved through local building code and/or fire prevention agencies.
Figure 1
Note: Ensure that the four (4) plastic washers provided with the DSB unit are used
inside the end mount assemblies at each end of the bar. The DSB touch sense will not
function correctly without these (non-conductive) plastic washers.
