Figure 4-3: Detector input for GMXS1 testing
Apply the required input to terminal 4, which is selectable as part of the detector programing op-
tions.
Active low = 0v applied to activate. Active high = 0v removed to activate.
When selecting the Active high option, it is essential to connect a permanent 0v to avoid unwanted
alarms. To activate, remove the 0v.
Selection of the test input is only possible through the GMSW7 SensTool software.
