3M™ Wireless Communication System Model XT-1
Installation Manual
Greeter Module
There is one space along the bottom right of the base station for the optional
greeter module. Perform the following procedure to install it.
4. Ensure that the base station is unplugged.
5. Remove the base station cover, see page 15.
6. Align the top of the greeter module with the installation slots.
7. Slide the sides of the greeter module board between the slots.
8. Carefully install the flat cable between the greeter module board and
the base station board. The left-to-right pin order is the same on both
boards: the left pin on one corresponds to the left pin on the other.
Greeter Alert Trigger Inputs
The installer can repurpose up to 4 of the existing input terminals on the XT-1 as
ALERT Message Trigger Inputs. Each of these 4 existing inputs now has two
modes. “Original Mode” maintains the inputs original function. For example,
shorting the SPLIT/CROSS input to GND toggles the XT-1 System between
SPLIT and CROSS mode for a Dual Lane installation. Assigning an ALERT
Message to this input changes the functionality. Now, shorting the
SPLIT/CROSS input to GND plays the ALERT Message assigned to that input
(such as Back Door Open). The message plays in each headset configured to
play the ALERT Message. See Figure 16 for an example.
