Automatic inhibits

The system supports automatic inhibits in the following instances.

Zones

When the UK and Commercial are selected (see Standards), 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.

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.

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).

Keypad User Logoff

If no keys are pressed on a keypad for a specific duration (see ‘Keypad Timeout’ in Timers), the user is automatically logged off.
