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).
