aa manual control which causes a voice alarm output condition to be given shall only be accessible at access level 2;

Signature

Praesideo is compliant.

The Praesideo system can enter the voice alarm output condition manually via control input contacts, the Open Interface and call station (keypad) keys, by starting a call with a high enough priority.

A voice alarm priority call can be manually activated in one or more individual zones or zone groups. Zone selection is possible via call station keypad keys or via the Open Interface (e.g. using a PC Call Station for graphical representation of zones with mouse or touch screen selection).

Zones can also be added to and removed from a running voice evacuation call using the ‘Start’ action, even from other call stations or control inputs on other system elements. A separate ‘Stop’ action is available to stop such a call from any location.

Praesideo uses the concept of audio output assignment to a dedicated zone. Because different zones use different amplifiers, the activation of an additional voice alarm zone will not affect other voice alarm zones.

Praesideo can be configured to abort lower priority calls and BGM (Background Music) if a voice alarm state is present.

The mandatory zone related indications are based on the priority of the active call in the voice alarm zones. This means that the lower priority boundary of the Zone status indicator for each zone should be set to include all priorities of possible alarm calls into that zone. Using priority level 224 as lower boundary is a safe choice, because then the Zone status indicator will cover all possible alarm priorities (224-255).

Praesideo is compliant.

The voice alarm condition is indicated on the Praesideo system by:

•A red indicator on all call stations (the system status LED).

•A textual indicator on the network controller display

•An output contact configured as voice alarm activated indicator (Emergency alarm indicator). This output contact can be used to control the General Voice Alarm Activated indicator.

The key-indicators on call station keypad kits (or regular keypads) can be configured for ‘Zone status’, to show that a (voice) alarm is active for a specific zone or group of zones. The indication is based on the priority of the active call in that zone, see 10.1. c.

Praesideo is compliant.
