Maximum external HV measure-
ment voltage (Note 4)
10,000v
NOTE 1 : This is the power consumption when none of the powered outputs
are active and the keypad is not connected. The rated power consumption
may be lower depending on relay configuration and alarm states.
NOTE 2: The control inputs as supplied with 5V from a “weak pull up”
circuit so that they can be controlled using dry contacts from a relay or
switch. A device with “open collector” outputs may be used. They can also
