Juno Net / Junior: practical field notes for testing, disablements, logic and restoration. Menu wording can vary by firmware and site configuration.

Before changing a live system: agree the test/disablement with the responsible person, identify any ARC/fire-routing connection and plant interfaces, decide what must remain operational, record every temporary change, and restore/verify everything before leaving.

Juno Net / Junior

GFE Juno Net has a dedicated Caretaker Test Mode for one-man testing and supports selective disablement for recurring service needs.

Protocol / ecosystemGFE addressable families

One-man / walk test

  1. Enter Caretaker Test Mode using the panel procedure for the installed Juno Net revision.
  2. Devices placed under caretaker test can be tested without filling the normal event log with every individual test.
  3. Observe the TEST state and ensure the mode is exited after the test route is complete.

Disable / enable

  1. Use the disablement functions for the required scope.
  2. Juno Net supports selective disablement: individual devices can be pre-designated so the front-panel selected-detectors disablement control affects only those devices.
  3. Review the disabled queue and clear all temporary disablements.

Cause & effect / groups

  1. Selective disablement is useful for recurring operational needs but must be clearly documented.
  2. Juno Net programming includes device reporting behaviours and network/node configuration; retain the site file before changes.
  3. Do not confuse a selective disablement list with a fire zone.

Engineer notes

  1. On networked Juno Net systems, understand main-panel versus node behaviour.
  2. Use GFE manuals for the exact firmware/revision.
  3. Record which devices are members of any selective-disablement set.
