Programming coded alarm signals

A coded alarm signal consists of at least three rounds of a series of pulses that
identify the active fire alarm zone. Each round consists of up to three digits (the
fourth digit is optional). Each digit consists of up to 15 pulses.

Note:

Entering a value of 0 terminates the round. For example, if IDC Code Digit

3 is set for 0, each round will consist of only digits 1 and 2.

To program a coded alarm signal, follow this general sequence of steps:

1. For each NAC, set the NAC type option for Coder.

2. Select the IDC Zone Type option, then program each IDC to activate all

NACs.

3. Select the IDC Code Digit 1 option, then for each IDC enter a number for the

first set of pulses in the coded alarm signal. Enter a number between 1 and
15. Do not enter a 0.

4. Select the IDC Code Digit 2 option, then for each IDC enter a number for the

second set of pulses in the coded alarm signal. You can enter any number
between 0 and 15.

5. Select the IDC Code Digit 3 option, then for each IDC enter a number for the

third set of pulses in the coded alarm signal. You can enter any number
between 0 and 15.

6. Select the IDC Code Digit 4 option, then for each IDC enter a number for the

fourth set of pulses in the coded alarm signal. You can enter any number
between 0 and 15.
