24 VDC Four Wire Smoke Detector Power
Up to one ampere for four wire smoke detectors can be drawn from TB3
Terminals 1 (+) and 2 (-). Power is removed from these terminals during
system reset. This 24 VDC regulated source is power-limited but must be
supervised via an end-of-line power supervision relay (refer to Figure 62
and Figure 63).
