IPDACT-2(UD) - Description
II-15
Doc.DM385-I
Rev. 4.0
OUT2 NO-C: terminals whose state is normal open. While the CPU is
working properly these terminals are in a short circuit state. Short
circuit is carried out through an electric-mechanical relay. The technical
data for this can be found in appendix V. 3.
Connectors associated to the inputs INPUT1 and INPUT2
INPUT1 (Normally Open): terminals associated to the input number 1
(zone 1). This input is supervised and considered inactive when a 1K
ohms resistance is detected between its ends. When an open circuit is
detected, the device, which should be connected to this input, is regarded
as having been disconnected i.e. it has been sabotaged.
INPUT2 (Normally Open): terminals associated to the input number 2
(zone 2). This input is supervised and considered inactive when a 1K
ohms resistance is detected between its ends. When an open circuit is
detected, the device, which should be connected to this input, is regarded
as having been disconnected i.e. it has been sabotaged.
In UL compliance installations, these inputs should not be used and
must be bridged with a 1K resistance. This resistor is factory
installed.
Tamper Connector
TAMPER (Normally closed): An additional input connecting to a box
tamper which indicates if the box is open. The input is normally closed.
Power Connector
+12/24V: It is possible to power the unit at either 12 or 24 volts.
GND: power ground terminal.
II - 5. LAN
The device connects to the LAN through an RJ45 (CN2) connector.
