Custom Alarm Setup - Black Box CRCW-12 User Manual

4.5.5.6.7 Custom Alarm Setup

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.
You can select any mix of the 80 alarm variables as shown in the tables that follow. As an example, for a custom alarm based
only on the occurrence of moisture alarm, condensate pan, pump, or 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 1 - 8...............Moisture alarm (No. 4) = 8
Custom Alarm number 9 - 16.............Fire/smoke (No. 10) + Condensate pan (No. 12) = 10 (2+8)
Custom Alarm number 25 - 32............Middle temp. sensor (No. 26) + Return humidity sensor (No. 29) = 18 (2+16)
The custom alarms are set up by entering the bitmask totals developed from the following tables:
