Typical Switch Hookup Detail
MAC-4R Control Panel
Notes:
1. All switch inputs are shown open and assumed to be held closed for secure state.
2. Total wire resistance should be kept below 100 Ohms for all 2 state circuits. Typical 22 AWG wire
has a resistance of 16.5 Ohms per 100 ft.
3. It is suggested where longer lengths than 5000 ft are required the conductor be sized at 18/2 or
larger.
4. 2 state wiring is the most common but does not allow for conductor supervision.
5. 3 state hookups provide switch status as will as near complete circuit supervision.
6. 4 state hookups provide complete supervision of all states of the circuit.
