System Options MenuPage 56HUA ResponseThis option controls the audible alarm associated with Hold-Up Alarms (HUAs).Note: All HUAs are disabled when an installer is using the Installer menu. HUA Keys Active (page 48) must be enabled to generate HUA alarms fromkeypads.AudibleThe control unit starts HUA alarm tones from keypads and loudspeakers, operatesHUA outputs, and activates any sirens. The sirens follow the Siren Time (see page46).SilentThe control unit keeps the HUA alarm silent: there are no alarm tones, and anysirens or HUA outputs remain inactive.DisplayedAll keypad displays show an HUA alert message immediately (a user does not haveto enter an access code to see the message). If more than one HUA is active, thedisplay scrolls through the alert messages at approximately one-second intervals.The control unit also starts HUA alarm from keypads and loudspeakers, operatesHUA outputs, and activates any sirens.HUA Confirm TimeThis is available only when Confirmation Mode is set to BS8243. This option determinesthe length of the confirmation time for confirmed HUAs.If the confirmation time expires after an unconfirmed Hold-Up Alarm (HUA), and the Hold-Up Device (HUD) is still active, the control unit omits the active device and communicates“Omitted HUD” to the ARC. If the system is unset, the control unit displays an alert at theappropriate keypads.If you wish to generate a confirmed HUA for test purposes only, you can set the HUAconfirm time to 0.Note: The time must be between 8 and 20 hours to comply with BS8243:2010 5.4.1.2.Tamper as Tamper OnlyThis is available only when Confirmation Mode is set to BS8243. The purpose of the optionis to ensure strict compliance with BS8243 when reporting tampers to ARCs.EnabledWhen an unconfirmed tamper occurs, the control unit sends only “Tamper” to theARC and activates any output configured as type Tamper (this follows Scantronic’sunderstanding that BS8243, Annex H.7.1 applies to all grades).DisabledWhen an unconfirmed Tamper occurs the control unit sends “Tamper”, “GeneralFault” and “Burg” to the ARC. In addition it activates any outputs of type Tamper andGeneral Fault.Note: This option does not comply with BS8243.The behaviour of the Disabled setting is used when Confirmation Mode is Basic orDD243.
