WARNING: We strongly recommend that no cause & effect programming should be attempted without the use of the pc down-load facility due to the extensive range of options available. However, if direct panel programming is unavoidable, a separate document entitled “Programming the Nexus 1-8 Loop Analogue Addressable Control Panel Without a PC” is available.
6.7.1 Cause & Effect Testing Testing of the panel’s fire and fault relays and all cause & effect outputs must be done with the system fully functional. There are two options: (i) Operate field devices and physically check programmed output devices for correct operation. (ii) Select engineer’s option 5: STATUS and operate devices with the System Enabled option as described in the Nexus 1-8 Loop Installation Manual. This will cause selected devices to go into fire and operate the panel’s cause & effect programming. Physically check programmed output devices for correct operation.
6.8 Final Commissioning 6.8.1 Select engineer’s Option 9: DEVICE TEST and carry out tests on all sensor devices. 6.8.2 Testing of the panel’s fire and fault relays and all cause & effect outputs must be done with the system fully functional. There are two options for testing the panels cause & effect: (i) Operate devices as required (ii) Use engineer’s Option 5: STATUS, selection 1 SYSTEM ENABLED to operate devices.
