23.11 Duress PINs
A user PIN with duress cannot be configured for the last user PIN in an allocation
of PINs for a specific number of PIN digits. Configuring duress with ‘PIN+1’ or
‘PIN+2’ requires either 1 or 2 additional PINs to be available after a specific PIN.
For example, for an allocation of 4 digit PINs, the total number of PINs available is
10,000 (0 – 9999), in this case, if using ‘PIN +1’ duress configuration, the last user
PIN that can be allocated duress is 9998. If ‘PIN+2’ is used then 9997 is the last
user PIN that can be allocated duress.
Also, if the duress feature is enabled then consecutive user codes (i.e. 2906, 2907)
are not permitted, as entering this code from the keypad would activate a user
duress event.
Once the system is configured for PIN +1 or PIN +2 in System Options [➙ 222] and
specific users enabled for duress (see Users [➙ 183]), it must not be changed
unless all the users are deleted and re-allocated user PINs.
23.12 Automatic inhibits
The system supports automatic inhibits in the following instances.
23.12.1 Zones
When the UK & Commercial are selected (see Standards [➙ 234]), the system will
provide DD243 functionality. In this instance the system will inhibit zones under the
following conditions:

Entry zone will not cause an alarm signal to the central station and cannot be
part of a confirmed alarm and hence will be effectively inhibited as required by
DD243.

If a single zone is triggered and another zone is not triggered within the
confirmation time (30 min default) but the first zone is still triggered, then the
first zone will be automatically be inhibited and no further alarms will be
triggered from this zone during the set period.
23.12.2 Access PINs
For Grade 2 systems: After 10 unsuccessful attempts with the incorrect PIN, the
keypad or browser will be disabled for 90 s; after a further 10 attempts with the
incorrect PIN, the keypad or browser will be disabled for a further 90 s. Once a
correct PIN has been entered, it will reset the counter back to zero allowing for a
further 10 attempts before disablement.
For Grade 3 systems: After 10 unsuccessful attempts with the incorrect PIN, the
keypad or browser will be disabled for 90 s; after each further attempt with an
incorrect PIN the keypad or browser will be disabled for a further 90 s. Once a
correct PIN has been entered it will reset the counter back to zero allowing for a
further 10 attempts before disablement.
23.12.3 Engineer Access
An Engineer can only access the system if permitted by a ‘Manager’ user type (see
‘Engineer’ attribute in User Rights) and only for a specified time duration (see
‘Engineer Access’ in Timers [➙ 230]).
23.12.4 Keypad User Logoff
If no keys are pressed on a keypad for a specific duration (see ‘Keypad Timeout’ in
Timers [➙ 230]), the user is automatically logged off.
