2.2. Addressing
Universal address cards are supplied with the mounting bases. A universal address card
slides into a mounting base and the fire monitor, when fitted to the base, reads the
address from the card.
A universal address card has seven removable pips that correspond to a seven bit binary
value. Each pip has an associated value, which is shown on the card: 1, 2, 4, 8, 16, 32,
64 (see Figure 1). Removing a pip makes this value valid, and remaining pips have a
value of “0”. The address is the sum of the values of all removed pips.
