Ultima OPIR-5 Detector36Sample Calculations for Analog Output CableMaximum load is 700 ohms. If an external device has an input impedance of 600 ohms, thecable resistance must not exceed 100 ohms, where maximum load = device load + cableresistance. For 16 AWG cable with resistance of 5 ohms / 1000 feet, the maximum distancefrom IR5500 and AO device is ((100 / 5 ) / 2) x 1000 feet = 10,000 feet.AWG Ohms/1000 ft Feet Meters#20 11 4,550 1,390#18 7 7,140 2,180#16 5 10,000 3,050Table 6: Distances from Receiver to Analog Output Load7.3 Spare Parts and AccessoriesTo order spare parts or accessories, please contact your nearest MSA Representative orMSA directly and give the following information: Configuration Number Description Quantity7.3.1 Spare Parts329071-1 Pan-Tilt Base Assembly329073-1329123-1Pan-Tilt Arm AssemblyBasic Mounting Arm Assembly329083-1 Methane Test Gas Film Kit329084-1329113-1329118-1Propane Test Gas Film KitAttenuatorLamp Replacement Kit954-021 5 mm T-handle hex key.
