Notes:
1. The type of executive devices to be connected to the outputs is to be defined by user and can
differ from the shown devices.
2. The load connection modules should be installed within the cases of executive devices
(except for discharge circuits).
3. For discharge circuits and explosion-protected devices the load connection modules can be
located in the proximity of them.
4. If an output is not in use, a 1kOhm - 0.5 W resistor can be used instead of the load
connection module.
5. Normally open and normally closed detectors can be combined and brought into the same
circuit if only one detector can be in activated status at the same time.
