Chapter 4: E2 Controller
NOTE: Display screens shown with a dashed border 
appear only if the application feature is enabled.
Custom Alarm Setup (Optional)
The E2 controller may be enabled to activate a Custom Alarm output and energize a designated N.O./N.C. relay. A custom alarm output is set up by adding the binary bitmask numbers assigned to the specific alarms and signal failures you wish to monitor via the relay and then entering them in the Custom Alarm Setup screen.
Figure
NOTE: Custom alarm display screens may appear even if the feature is not enabled. In this case, changes made to these screens will have no effect.
You can select any mix of the 48 alarm variables as shown in the tables that follow. As an example, for a custom alarm based only on the occurrence of moisture alarm, fire/smoke, condensate pan, failure of the return humidity sensor, you would enter the following bitmask values for the applicable alarm numbers and enter 0 for the rest:
Custom Alarm number | Moisture alarm (No. 4) = 8 |
Custom Alarm number | Fire/smoke (No. 10) + Condensate pan (No. 12) = 10 (2+8) |
Custom Alarm number | Return humidity sensor (No. 29) = 16 |
The custom alarms are set up by entering the bitmask totals developed from the tables shown next.
