Configuring Contacts/Alarms
Note The terms contact and alarm are used interchangeably to mean the same
thing. Alarm is currently displayed on the OSD, although contact is a better
description since it is not an audible alarm but a change in electrical state to
the contacts resulting in a programmed response.
Note Remember you access the OSD by pressing 90 Preset.
Up to four contacts (called alarms on the display) can be programmed. The contacts are
sampled 16 times per second. See Table 5-3 for a list of possible contact states.
Table 5-3 Program Contact Submenu: Contact States
If: Then:
Contact is disabled The dome ignores a change of state in the contact input.
Contact is enabled and
not programmed
The dome ignores a change of state in the contact input.
Contact is enabled and
programmed
The dome performs the action programmed for the contact input when a change of state
occurs.
More than one contact
occurs
The dome performs the action for the first contact followed by any others in numerical
order.
• After a contact is triggered, the system confirms that the contact is both enabled
and programmed. As long as no other contact is active, the newly triggered contact
performs as programmed.
• The dome stays in the contact state until the contact is acknowledged. Any further
triggered contacts are not serviced until after the first one is acknowledged, and
then the subsequent contacts are activated in numerical order, starting at the
lowest number.
• A contact cannot be reactivated until it has been both acknowledged and returned
to its normal position. After acknowledgment and the contact change of state, the
cycle can begin again.
If any contacts are
active
AL displays on the monitor near to the dome’s ID and lists all active contacts in
numerical order. You cannot tell which contact is currently active except by viewing the
function occurring on the monitor. AL remains on the monitor until all contacts are
acknowledged.
