22 – Double Knocks
(Default = 002)
This counter is used only for wards selected by the Multiply Ack attribute (page 38). The
counter determines how many “knocks” are needed within the Double Knock period
(page 59) to cause an alarm at a zone that has the Double Knock attribute (page 30). If
a ward is not selected to use this counter, two activations are required.
23 – Tst Call Strt (Default = 000)
Specify a value for this timer only if you want on-board modem to make automatic test
calls to an Alarm Receiving Centre (ARC) at fixed intervals. These are known as "static" test
calls. The panel will make the first test call at the time you specify for Tst Call Strt, then at
fixed intervals specified by the Test Call Int timer. For example, if you specify 003 for Tst
Call Strt, and 010 for Test Call Int, the panel will make the first test call at 03:00, then the
next calls at 13:00, 23:00, 09:00, 19:00, etc.
This option is not applicable to M550 and M750 systems.
24 – Test Call Int (Default = 000)
If you have specified a value other than zero for Tst Call Strt, this timer sets the fixed
interval (in hours) between automatic test calls to an Alarm Receiving Centre (ARC).
If Tst Call Strt is zero, Test Call Int specifies the maximum
period of time between calls to
an Alarm Receiving Centre (ARC). The on-board modem automatically performs a test
call if it has not made another type of call to the ARC within this period of time. This is
known as "dynamic" test call.
Setting the value to zero prevents static or dynamic test calls from being made.
This option is not applicable to M550 and M750 systems.
25 – Reset Alg. (Default = 004)
This is applicable only if the Remote Reset attribute is set for a ward (page 37). The Reset
Alg option is a 3-digit number that identifies the algorithm used to generate the remote
reset code. An alternative algorithm can be selected, but this must correspond to the
algorithm used by the Alarm Receiving Centre (ARC), otherwise the code returned will be
incorrect.
If the value of Reset Alg is greater than 20, a 6-digit seed code is generated, and the
remote reset code returned is 6 digits.
26 – Payment Time (Default = 000 Days)
The installation company may use this timer to prevent the users from setting the system.
When the timer expires, users are unable to set the selected ward (as determined by the
Payment Timer ward attribute; see page 37) until the engineer has reset the system or the
user has entered a Remote Reset code (as described in the User's Guide).
To disable this feature, set the timer to 000.
27 – Hi Security (Default = 020 Minutes)
This timer determines the length of time that a secure ward (page 37) can remain unset
before the system automatically attempts to set it. When a secure ward is unset,
activation of any zone in that ward resets the timer.
