Setting the Address

The CHQ-AB must have its address set before system operation. Using an installation plan that shows the proper location
for each device, find the address for the CHQ-AB to be installed. Check that the address and location on the plan match
correctly. Address is any number from 1 to 127. For address setting, use the Hochiki TCH-B100 Hand Held Programmer
and write the address number on the beacon after setting. When address changing, renew the number on the label. See
the TCH-B100 instructions (2-3-0-237) for further details of the setting method.
