Keypad Blanking

If the Keypad Blanking Option is enabled the panel will turn off all lights and LCDs on the keypads if no
key is pressed for 30 seconds. The keys, however, will remain backlit.
The panel will turn the lights and LCDs back on if entry delay begins or an audible alarm occurs. The
lights and LCDs will also come on if a key is pressed or, if the Code Required to Restore Blanking
Option is enabled, a valid User Code is entered.
If the Power Save Option is enabled the panel will blank all keypad lights including backlighting when
AC power fails, in order to conserve the back up battery.

Loop Response

The normal loop response time for all zones is 500 milliseconds. The panel will not consider a zone
violated unless it is violated for at least 500 milliseconds.
If Zone 1 is Fast Loop Response is enabled the loop response for zone 1 will be 40 milliseconds.
Typically this can be used for vibration type sensors.

Keypad Tampers

If the Keypad Tampers Enable option is selected the panel will display and transmit a General System
Tamper reporting code if any keypad is removed from the wall. When the keypad tamper is restored the
panel will transmit the General System Tamper Restoral reporting code. All keypads should be properly
installed and secured before enabling this option.
By enabling Tampers/Faults Do Not Show as Open, Faults and Tampers will not show as open on the
keypad, and will be hidden from the end user. If the option is disabled, Faults and Tampers will show as open.
Entering and exiting Installer's Programming will not reset the system tampers. All tamper conditions
must also be physically restored.
Once a zone is tampered or faulted, it must be completely restored before the trouble condition will clear.

LINKS1000 Cellular Communicator

The LINKS1000 cellular communicator can be used three different ways; as the sole communicator for the panel,
as a back up for either or both phone numbers or as a redundant back up to the land line communicator (the
panel will call both the land line and via the LINKS). A LINKS Preamble is programmable for each phone
number in the event that the land line number is local but the LINKS is required to dial an exchange. When
programming a LINKS Preamble, all unused digits must be programmed with a hex decimal "F".
5.26.1

Using LINKS1000 as the Sole Communicator

The panel can be programmed to report only using the LINKS1000 cellular communicator when an event
occurs. To program this select only the LINKS1000 for the Communicator Call Direction Options for the
event. In addition the Call LINKS as well as Land Line option must also be enabled.
When the selected event occurs the panel will only attempt to call central station using the LINKS.
5.26.2

Using the LINKS as a Backup Communicator

The panel can be programmed to call using the LINKS1000 cellular communicator if the panel is having
difficulty communicating an event using the land line. To program this select both the phone number and
LINKS options for the Communicator Call Direction Options for the event. In addition the LINKS is Backup
of Land Lines option must be selected.
When used as a backup communicator the panel will attempt to call the central station in the following manner:
• the panel will try to call using land lines - if unsuccessful the panel will try to call using the LINKS
• if unsuccessful the panel will try to call using the land lines
• if unsuccessful the panel will try to call using the LINKS
This process will continue until the panel has successfully communicated with the central station or the
Maximum Dialing Attempts has been reached.
