Clause / Requirement Compliance Signature

7 The voice alarm condition

7.1 Reception and processing of fire signals

7.1.1The VACIE shall be capable of receiving and processing alarm signals from the CIE or from manual control on the VACIE or both, and causing the appropriate voice alarm outputs to be activated within 3 s or on expiry of any delay period (see 7.4).

Praesideo is compliant.

Alarm signals from the CIE can be received from input contacts and the Open Interface. Manual control is possible via input contacts, the Open Interface and call station (keypad) keys.

NOTE - See Annex E for additional information relating to the interface between the VACIE and the CIE.

If input contacts are used for connection of the CIE to the Praesideo system then the input contacts can be monitored for short circuit and open line. If the Open Interface is used for connection of the CIE to the VACIE, the communication is monitored using keep-alive messaging.

7.1.2 The mandatory indications and or outputs shall not be	The Praesideo system offers 32 discrete alarm priorities.
falsified by multiple alarm signals received simultaneously	Correct configuration assures that mandatory indications
from the CIE and/or manual controls.	and or outputs behave consistently when multiple alarm
	signals are received simultaneously from the CIE and/or
	manual controls.
	Higher priorities overrule lower priorities in case of
	resource or destination conflicts. Calls with the same
	priority operate on first come first serve basis, except in the
	case of priority 255: calls with the same priority 255
	overrule each other, so the latest becomes active. This
	assures that high priority microphones that are left behind
	in an active state will never block the system.

7.1.3Where the VACIE and CIE are in separate cabinets, failure of the transmission path between the CIE and the VACIE shall not result in any loss of control or any change of state of the VACIE.

The Praesideo system is an autonomous subsystem that can operate without connection to the CIE. The effect of the failure of the transmission path between the CIE and the Praesideo system is limited to fault reporting and losing interaction between the CIE and the Praesideo system.

7.2 Indication of the voice alarm condition	Praesideo is compliant.
7.2.1 The presence of a voice alarm condition shall be
indicated on the VACIE, without prior manual intervention,
by:
a a visible indication by means of a separate discrete light	A voice alarm condition is indicated on the Praesideo
emitting indicator (the General Voice Alarm Activated	system by:
indicator);	• A red indicator on all call stations (the system
	status LED).
	• A textual indicator on the network controller display
	(the ‘emergency menu’ that is automatically shown
	when the system enters the voice alarm state).
	• An output contact configured in the site specific
	data as voice alarm activated indicator (Emergency
	alarm indicator). This output contact can be used to
	control the General Voice Alarm Activated
	indicator.
	• The installer must mount a red (flash) light to
	indicate the voice alarm condition, clearly visible
	from the front side of the rack, behind the glass
	door of the rack.
b a visible indication for each activated voice alarm zone	The keys on call station keypads can be configured to have
where manual controls are provided (see 10.2);	their key indicator show that an emergency is active for a
	specific zone or group of zones. This is achieved by
	configuring the action ‘Zone status’ for the key, and
	configuring the lowest possible alarm priority (224) for that
	action to ensure that for all alarm priorities (224 - 255) the
	indicator will be activated.
NOTE - This may be by means of separate discrete
indicators or an alphanumeric display as specified in 13.8.

can optional audible indication, as specified in 7.3.

An output contact of a Praesideo system component can be configured in the site specific data as audible voice alarm activated indicator (Emergency alarm buzzer). This output contact can be connected to a buzzer. This way the voice alarm condition is indicated audibly.

7.2.2The audible warning shall be capable of being silenced at access level 1 or 2.

The connected buzzer (see 7.2.1.c) can be silenced by acknowledging the voice alarm condition. The voice alarm condition can be acknowledged by means of an input contact, call station key, the front panel menu of the network controller or via the Open Interface.
