Emergency Alarms are able to be configured in any system that uses an LSI-16 or LSI-16e. Emergency alarm inputs are accepted via the CI-1 Alarm inputs, the LSI-16 Emergency Inputs, LSI-16e or IM-16 inputs or a GPIO-1 Inputs configured for emergency use.
Alarm Inputs are able to be associated with both an Emergency Zone and an Emergency Message via the Vocia Software Interface. When activated, these inputs will place the Vocia World into Emergency Mode and cause the associated Emergency Message to be played in the affected Zone. The intention is to allow a fire detection system (CIE) to trigger a particular message in a nominated Zone, for example, Alarm Input 1 may trigger a ‘warning’ message in Emergency Zone 1; Alarm Input 2 may trigger an ‘evacuate’ message in Emergency Zone 1.
Alarm Inputs are enabled by a transition on an input. An Alarm state on an input can be canceled by a physical Alarm Reset, LSI VTP or by the selection of another Alarm State in the same Zone.
Each Alarm Input can be assigned to Emergency Zones on the basis of one input per Zone, or many inputs per Zone. Each Alarm Input can also be associated with a particular Emergency Message. By assigning an input with a 'Mute' Alarm command, the currently playing Emergency message can be stopped while still leaving the system in an Emergency state.
When more than one Alarm Input is assigned to an Emergency Zone for the purpose of playing multiple messages to that Zone, only one message at a time will be played and the last triggered Alarm Input will be acted on.
Example
Alarm Input 1 is configured to play Emergency Message A to Emergency Zone 1.
Alarm Input 2 is configured to play Emergency Message B to Emergency Zone 1.
If Alarm Input 1 is enabled, Emergency Message A will commence playing in Emergency Zone 1. If Alarm Input 2 is then enabled, Emergency Message A will immediately stop and Emergency Message B will commence playing in Emergency Zone 1.
If Alarm Input 1 is then re-enabled, Emergency Message B will immediately stop and Emergency Message A will commence playing in Emergency Zone 1
These will allow connection of fault detection circuits from external devices such as power supplies, UPS units, Ethernet switches and third-party amplifiers. Fault Inputs can be configured in the Vocia software to activate on either a high to low or a low to high transition.
When a Fault Input on the IM-16 is enabled, unless a Monitoring Fault has been detected on that Input, the following will occur:
A corresponding Yellow LED will illuminate on the Life Safety Interface front panel.
The LSI-16 will report a Fault, of the type assigned to that Fault Input and will respond accordingly for that type of fault.
Other Fault Inputs on the Life Safety Interface will continue to operate as normal.
When a Reset Input has been configured and it is asserted, all Emergency messaging being played to the assigned Emergency Zone will cease. Once an input has been designated with Reset Input functionality, it can be configured as High Range, High Range Monitored or TTL logic level, and designated as either a High or Low active state. Single or multiple inputs may be associated with a single Zone's reset control.
