9.6 SPECIAL CONNECTIONS TO DETECTORS
9.6.1 CONNECTING THE S231I+ OR S231F+ (USING ZAU401 REV 2)
* * W A R N I N G * *
Even though the S231i+ is listed as hazardous area rated, this compatibility is for a direct
connection – not through an intrinsically-safe isolator, and thus cannot be used in hazardous
area applications. For IS applications refer to Section 9.4.
The S231i+ and S231f+ detectors are not directly compatible with the F3200. However,
compatibility can be achieved by using the PA0838 ZAU401 (Rev 2) Zone Adaptor unit
between the panel and the detectors.
The ZAU401 can be thought of as a single zone circuit module that can be added to a panel
to make it compatible with a wider range of detectors. The ZAU401 supports up to 2mA of
quiescent detector current, thus only 5 S231i+ or S231f+ detectors can be used on each
ZAU401. It operates off the panel’s 24V supply and consumes 20mA in the normal state.
Only one ZAU401 can be connected to each circuit on the panel. Also, do not use a Rev 1 or
non-Vigilant manufactured ZAU401 as these have different characteristics.
A 220E 5W resistor (Vigilant part number RR0415) must be placed in series with the
detector circuit at the ZAU401 to limit the maximum current to any detectors in alarm.
Wiring of the ZAU401 to the panel and S231i+ / S231f+ detectors is shown in Figure 9.6.1.1.
