IPDACT-2(UD) - Configuration
III-31
Doc.DM385-I
Rev. 4.0
DHCP Client activation/deactivation
The DHCP client is a device functionality permitting a DHCP server to assign
an IP address and mask to the Ethernet interface plus an output gateway.
The majority of the ADSL routers have a DHCP server so the IPDACT-2(UD)
automatically configures and can connect to Internet through the router.
The registrar consists of a one-digit field which admits a value of 1 to activate
the client and a value of 0 to deactivate it. The field contains a number
verification digit. By default this is configured to 1 i.e. the client is activated.
Switch time for the output relay
The two output relays in the device (terminals OUT NO) have two
complementary states, i.e. when the first is open the other one is closed.
These states show device connectivity with the IP receiver (VisorALARM) so
when the IPDACT-2(UD) loses connectivity the relay closes (the other stays
open) remaining in this state while connectivity is lost. This behavior can be
modified by introducing periodicity in the status of the relays, i.e. that this
remains closed during a programmable period of time, open for a set time (2
seconds) and returning to the closed state. This behavior is maintained while
there is no connectivity.
Switch time can take values between 0 and 300 seconds. A zero value
means that the relay permanently remains in a closed position provided that
the connectivity state does not change.
Action to execute when a telephone line failure occurs
The IPDACT-2(UD) supervises the telephone line so if a failure is detected, it
can carry out three actions:
• Send an alarm to the VisorALARM (programmed value 2).
• Activate the output relay in the same way as if a communication failure
had been detected (programmed value 1).
• Both of the above actions (programmed value 3).
The possibility of not doing anything at all exists together with the above
actions (programmed value 0).
In UL listed fire installations, this value must be programmed to 0.
Maintenance VisorALARM address
Apart from the main VisorALARMs and the backups, you can send trouble
alarms (300-388 CONTACT-ID group) to a third VisorALARM known as
maintenance. This device does not have IP module registers, nor monitors its
status and does not have backup. The main VisorALARMs and the backups
execute those functions. The maintenance device only receives trouble
alarms and resends them to the automation software.
