Mounting the A200
To avoid possible damage caused by moisture, mount the A200 inside the building, not in the menu sign.
Choose a location near the intercom base unit and within 5 feet of a 120 VAC, 60 Hz electrical outlet. It
is best to firmly attach the detector to a wall or other surface to prevent movement, which could damage
the connections. Mount the detector as follows:
1. Use the A200 bottom plastic case as a template to mark two holes on a wall or other surface.
2. Using appropriate mounting hardware (not supplied), attach the A200 to the wall or mounting surface.

Note
The Model A201 Loop Detector is designed specifically as an optional
accessory for the 3M C921BA or later Base Station only.
1. Remove the right-hand and loosen the left-hand top covers from the C921BA base station. Be careful
that the C921BA circuit board does not fall out of the plastic base.
2. Remove and discard the white nylon programming cord holder from the base station.
3. Plug the ribbon cable onto connector J7 on the base station so the center five holes are engaged. The
colored wire should be on the left side of both connectors.
4. Position the hole near the center of the A201 circuit board over the plastic peg on the base station. Route
the ribbon cable to the left of transformer T1 as shown in Figure 3.
5. Attach the left-hand base station cover.

Note

both connectors.
