7 The voice alarm condition
7.1 Reception and processing of fire signals

Praesideo is compliant.

7.1.1 The 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).

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 falsified by multiple alarm signals received

simultaneously from the CIE and/or manual controls.

The Praesideo system offers 32 discrete alarm priorities.

Correct configuration assures that mandatory indications

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.

7.1.3 Where 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 emitting indicator (the General Voice Alarm

Activated indicator);

A 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 (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 where manual controls are provided (see 10.2);

The keys on call station keypads can be configured to

have 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.
c

an 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.

7.2.2 The 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.
