); cut back 5 mm (0.2 in) of
insulation.
– Impedence: Internal pull-up 10 kOhm to +5 VDC.
– Input voltage range: -5 VDC minimum to 40 VDC maximum.
– Input voltage treshold: low voltage 0.8 V maximum, high
voltage 2.4 V minimum.
– Configurable as active low or active high.
Use the alarm input to connect external alarm devices such as
door contacts or sensors. A zero potential make or break
contact can be used as the actuator (use a bounce-free contact
system).
Relay output
– Max. wire diameter AWG 22-28 for both stranded and
solid; cut back 5 mm (0.2 in) of insulation.
– Output relay switching capability: Max voltage 30VAC or
+40 VDC. Max 0.5 A continuous, 10 VA.
– Max. 42 V allowed between camera ground and each of the
relay pins.
