10. Status Indication of Relays: The system shall provide visible status indication of all
relays through the window of each control panel. The visual indication shall
disclose On/Off status and relay number.
11. Service Override & Priority Override: The control panel shall provide a three
position master-service override for the control unit. The service override shall not
be accessible from the exterior.
The master service override provides a single three position switch with the option
of All Off, Auto, and All On, respectively. This master switch shall operate all of the
relays in the controller. This switch shall override and supersede all commands
from the logic board when the switch is in the All On or All Off position. The master
switch shall function to override all the relays should the logic board programming
differ from the space function.
The system shall remember the last command to the individual relays. Upon
returning the master override switch to the Auto position, the relays shall return to
the most recent command state. This will occur even if the last command
happened during the master override condition.
Additionally, the system shall provide external priority override for the entire panel.
Through an externally maintained contact the override card shall place the panel in
a priority state. This external contact will supersede any other programmed state
and will command all the relays ON or OFF depending on operational choice. This
priority state will continue until the external contact is removed. Once the external
override is removed the control panel will return the relays to the appropriate
programmed state.
12. Lockable Enclosure: Each control panel shall be enclosed in a lockable NEMA
class 1 enclosure. The enclosure shall be manufactured out of 1/16" steel and
