          *1 Risk time according to IEC60947-5-3 is 150 ms + 2 ms × (number of units cascaded -1).
          *2 If the OSSD operation is open/close link mode, Detect→ Not detect: 20 ms + 2 ms × (number of units cascaded -1), Not detect → Detect: 30 ms + 25 ms × (number of units cascaded -1)
          *3 430 ms when locked at the same time the actuator is detected.
          *4 Acceptable door operation frequency is 3 Hz if the OSSD operation is open/close link mode. In that case, operation distance is Sao(OFF→ ON) = 3 mm 0.12", Sar(OFF→ ON) = 10.5 mm 0.41".
          *5 Do not apply excessive torque (0.45N·m or higher).
          *6 Power consumption temporarily increases (Max. 10.5 W, Approx. 0.2 s) when the lock control input(s) is(are) turned ON. After that, current consumption will be within the specification.
          *7 When stored for a long period of time, please store it at a temperature of 55°C 131°F or lower.
