SpectraLink 1728 Computer Hardware User Manual


 
44 REFERENCE & INSTALLATION MANUAL
10.6 SYSTEM REAL-TIME CLOCK
Section [280]
Program the current time into section [280] using the 24-hour clock (i.e. 8:30PM = 20:30).
10.7 CLOCK ADJUST
Section [088]
000 = Disabled, 001 to 255, Default = Disabled
001 to 127 = + 1 to +127 seconds
128 to 255 = -1 to -127 seconds
If you notice a gain or loss in control panel time, calculate the average gain or loss per day and program the opposite
amount in order to automatically correct the time setting every 24 hours.
Example: If a control panel loses 4 minutes per month, this represents an average loss of 8 seconds per day.
Therefore, programming 008 (plus 8 seconds) into section [088] would compensate for the 8-second loss.
10.8 KEYPAD TAMPER SUPERVISION
Section [128]: General Options
Option [7] OFF = Keypad 1 Tamper Supervision Disabled (default)
Option [7] ON = Keypad 1 Tamper Supervision Enabled
Option [8] OFF = Keypad 2 Tamper Supervision Disabled (default)
Option [8] ON = Keypad 2 Tamper Supervision Enabled
The control panel can be programmed to monitor the on-board tamper status of one or two keypads in the system. If
Keypad 1 Tamper Supervision is enabled, the control panel will verify the on-board tamper status of a keypad whose
Keypad Zone Jumper (J1) is set to on. If Keypad 2 Tamper Supervision is enabled, the control panel will verify the
on-board tamper status of a keypad whose Keypad Zone Jumper (J1) is set to off.
Regardless of whether the keypad zones are being used or not, if more than one keypad has the
same Keypad Zone Jumper setting, Keypad Tamper Supervision will be lost. For example, if two of
the keypads in your system have the keypad zone jumper (J1) set to on, the control panel will not
recognize a Keypad 1 Tamper Supervision Failure.
If a keypad tamper occurs, the control panel can transmit the appropriate Zone Tamper report code (see page 34) as
originating from the zones specified by the Table 9. If the zone (as specified by Table 9) is enabled, the control panel
will report the tamper as originating from the partition where the zone is assigned. If the zone is not enabled, the
control panel will send the Zone Tamper report code as originating from partition 1. A Tamper/Zone Wiring Failure
will also appear in the keypads’ Trouble Display (see page 50).
When Reassign Keypad Zone 2 is enabled (see section 5.2), the Keypad Tamper Supervision for
keypad zone 2 is lost. Therefore, Keypad Tamper Supervision will
ONLY function on Keypad Zone 1.
10.9 KEYPAD AUDIBLE TROUBLE WARNING
Section [127]: General Options
Option [3] OFF = Keypad Beep on Trouble Disabled
Option [3] ON = Keypad Beep on Trouble Enabled (default)
When enabled, the keypads emit an intermittent beep tone whenever a trouble condition occurs in the system. The
intermittent beep tone remains activated until the user enters the Trouble Display by pressing the [
TBL] or [TRBL]
key. The intermittent beeps will re-initialize whenever a new trouble occurs or the trouble restores and re-occurs.
