Figure 7. Connecting 2- and 4-wire smoke detectors to the panel
Note: The 2-wire smoke setting (in program mode) must be on when using four-wire smoke detectors as shown in Figure 7.
See Onboard options - inputs settings on page 99 for complete details.
If 2-wire smokes with built-in sounders are used (521INCSXT), a polarity reversal relay (model 405-03) may
be used to activate the sounders on all smoke detectors during a fire alarm. See Figure 8 on page 21. An output
must be used to activate the polarity reversal relay. This output must be configured for fire alarm trigger, and
siren tracking response (001-10).
Note: Onboard outputs 1 or 2, SnapCard outputs, or output module outputs may be used to activate the polarity reversal
relay.
Maximum alarm current is limited to 1.0 A that the panel can source to all external devices. Be sure to include
the alarm current for all sounder smoke detectors in the alarm current calculation.
