Use the [^] or [Ў] keys to select the correct alarm relay action for the application, Latch, Sentry or Non-Latch. Selecting “Sentry” enables the Sentry controller to make all alarm action decisions. * indicates the current selection. • Gas Factor: A calibration standard of Methane may be used in conjunction with scaling factors to cause alarm function in %LEL scale of another gas. See Appendix I for a list of the scaling factors. Note that if the 5100-02-IT is interfaced to a Sentry controller t
