3.4.1NAC Configurations

In these configurations, the sounders are controlled and powered from the control panel’s NAC power circuit or a remote NAC power circuit. The positive (+) wire from the NAC or D132B Multi-use Reversing Relay Module connects to Terminal 5 and the negative (-) wire connects to Terminal 4 (refer to Figure 3.2, Item 3 on page 14). The sounders on the loop follow the NAC configuration programmed at the control panel. The DIP switches (refer to Figure 2.1, Item 15 on page 4) are set as shown in Table 3.1.

WARNING! DIP switches 1 and 2 must be either both on

! or both off. Having one on and the other off could result in incorrect operation including failure to alarm.

Position 1 and 2 off;

3 and 4 either both on or both off.

Control panel NAC circuit power is applied to the base to Terminals 4(+) and 5(-). The sounder follows the configuration of the NAC. The positions of switches 3 and 4 have no affect.

Table 3.1 NAC Configuration DIP Switch Settings

–NAC Follower (Direct Wire) Configuration: The sounders on the loop follow the signal on the NAC terminals as pro- grammed at the control panel. Refer to the control panel's installation manual for NAC configuration instructions. This configuration requires an extra pair of supervised wires for the sounder circuit (refer to Figure 3.2, Item 3 on page 14).

–Reverse Polarity Configuration: Tthe sounders in a loop activate due to reversed polarity on the power line. The output pattern is not controlled by the base in this operat- ing mode; it follows the signal on the head terminals as programmed at the controlpanel.
