4. WIRING MATERIALS AND WIRING METHODS
Do not wire near equipment that is a strong source of noise.
Do not wire in parallel to commercial power supplies or power lines.
Do not use aerial wiring. All of these installation could result in a malfunction.
 Power line wiring
For the wiring materials of power input wires, use wires that have a resistance lower than the maximum allowable
resistance found using the formula below.
To simplify the calculation method in this example, the calculation method is described for the condition where the all
detectors are installed farthest from the power supply device (so that the allowable resistance is minimized).
Calculation method for wire length in one
direction from power supply unit to this detector
Maximum allowable resistance
value for wire material R [Ω/km]
Vc: Output voltage of power supply unit [V]
Vs: Minimum operating voltage of this device = 9 V
L : The wire length from this device to power supply unit (km)
i : Current consumption of this device = 0.025 A

Detector 1
A power supply of 9.0 V to 28.0 V DC is input. It has the
polarity.
This is the 1b non-voltage output.
The allowable contact capacity is 30 V DC/0.3 A
(resistor load).
* When power is not supplied,the output opens.
This is the 1b contact component non-voltage output.
The allowable contact capacity is 30 V DC/0.1 A
(resistor load).
* When power is not supplied,the output opens.
