Bosch DS150I Installation Guide - Page 4

8.0 Application Notes 8.1 General Double entry/exit doors without a center post present a problem resulting from a gap that might exist between doors. While the gap is usually filled with soft or pliable weather stripping, there is an opening that vandals can use to insert an object (such as a comb or ruler) through and into the coverage pattern of the detector. If the object is a different temperature from the background, the DS150i interprets the temperature change as a request to exit. Install a DS150i over the center of double doors with a center post. When there is no center post, consider an alternative mounting option to move the center of the pattern away from the gap. 8.2 Ceiling Mount Mount the DS150i to the ceiling and away from the door. Longer objects can still be used to enter the coverage pattern. This type of entry would now be much more difficult. 8.3 Dual Mount Install and center one DS150i over each of the two doors and wire the outputs so either detector permits exiting. Reduce the probability of interference from foreign objects by masking out the inside zones (K & L on one detector, A & B on the other detector). Refer to Figure 10.
