Unlatching latched output devices
Latched outputs are devices that are configured to shut down air handlers and
dampers automatically when an alarm activates, and to keep them shut down
until they are manually unlatched and restored. For this reason, devices
configured as latched output devices must be manually unlatched and then
restored.
When outputs have been latched, the panel generates an “Outputs are latched”
event. The unlatch command affects all latched output devices system-wide. You
can assign the Unlatch Outputs command to a programmable key on the front
panel or to one of the following modules: E-ISO, E-IDC1A, E-IDC1B, or E-IDC2B.
To unlatch latched output devices:
1. Press the Unlatch Outputs button on the control panel (if programmed).
— or —
Press the Unlatch Outputs module button (if programmed).
