1.5 Resetting 4-Wire Detectors
General
4-wire detectors can be reset by using one of the function relays on the panel. The relay is not
programmed for any use, that is, it is unassigned. The next requirement is that a non-zero duration
be programmed for it (See “2.7 Outputs Dialog” on page 17) A duration of zero disables this
function. Once this is done, wire the power for the device as shown in Figure 1. A third party power
supply (must be UL/ULC-listed compatible power supply suitable for fire applications) can be used
instead of the Aux Power as shown. Whenever the System Reset operator key is pressed when
neither LED is flashing, causes the relay to operate for the duration programmed.
