How to test a beam sensor pair
After all the beam sensor pairs are fully commissioned use the appropriate test card (S4-34741-50) to
obscure the beam to simulate a FIRE or FAULT condition.
If a Test Keyswitch unit is connected to a 'beam transmitter' of a beam sensor pair then, if appropriate,
operate the switch to test the beam sensor pair. A test using a Test Keyswitch is not applicable for S4 beam
sensors converted to be backward compatible.
