Allied International Home Security System Voltages above +45 V may damage the optical coupler

Camera interfaces

DOLPHIN The inputs can be connected directly to +5 V. If higher voltage is used a resis- tor will have to be switched in series: at +12 V use a 470 Ω resistor, at +24 V use a 1.2 kΩ resistor. (DOLPHIN)

Caution DOLPHIN

Voltages above +45 V may damage the optical coupler.

OSCAR The inputs can be connected directly to +5 V. If a higher voltage is used, an external resistor must be placed in series: at +12 V use a 820 Ω resistor, at +24 V use a 2.2 kΩ resistor. (OSCAR)

Caution OSCAR

Voltages above +45 V may damage the optical coupler.

MARLIN The inputs can be connected directly to +5 V. If a higher voltage is used, an external resistor must be placed in series: at +12 V use a 820 Ω resistor and at +24 V use a 2.2 kΩ resistor. (MARLIN)

Caution MARLIN

Voltages above +45 V may damage the optical coupler.

GUPPY The inputs can be connected directly to +5 V.

Caution GUPPY

If using voltages higher than + 5 V the input of the cam- era will be damaged.

To avoid damage of the input, use an external resistor in series (outside of the camera).

Recommendations for resistors by voltages higher than + 5 V:

•At +12 V use a 18 kΩ resistor.

•At +24 V use a 47 kΩ resistor.

For details seeFigure 25: Input block diagram (GUPPY) on page 51.
