11 Occupant Warning Systems

The EV20, EV40, EV60 and EV120 are compact single zone occupant warning devices that when triggered produce Alert and Evacuation signals to meet the requirements of AS1670.4.

EV20

At the heart of an EV20 single zone occupant warning system is a microprocessor that generates the alert and evacuation signals, controls timing and the input / output.

If an FACP warning system input is received when the rotary switch is in the AUTO position the EV20 will begin to output the “Alert” signal for a duration determined by the setting of the 4 way DIL switch SW1. The set duration is termed the changeover timeout and ranges from 0 seconds to a maximum of 300 seconds.

If the time out is set to 0 seconds then the alert signal is bypassed and the evacuation signal commences immediately. The operator can manually stop the sequence by turning the rotary switch to the ISOLATE position.

IC4 performs the task of an audio amplifier with TX1 providing the impedance matching to a 100 volt speaker line. The alert and evacuation signal output Stages are set by adjusting RV1 and RV2 respectively.

Short or open circuit speaker faults are detected by the fault monitoring circuitry and will result in the illumination of the FAULT indicator mounted on the front panel control module.

Public Address

A microphone and pre-amplifier (Order Code 222-0007) is used to provide the public address capabilities.

EV20 Verbal Messaging

An optional verbal messaging PCB (Order Code 222-0026) is available and is mounted directly onto the main board.

EV40

At the heart of an EV40 single zone occupant warning system is a microprocessor that generates the alert and evacuation signals, controls timing and the input / output.

If an FACP warning system input is received when the rotary switch is in the AUTO position the EV40 will begin to output the

“Alert” signal for a duration determined by the setting of the 4 way DIL switch. The set duration is termed the changeover timeout and ranges from 0 seconds to a maximum of 540 seconds. If the time out is set to 0 seconds then the alert signal is bypassed and the evacuation signal commences immediately. The operator can manually stop the signal sequence by turning the rotary switch to the

ISOLATE position.

Amplifier 1 & 2 provides 40watts of audio output at 8 ohms which feeds TX1 to provide the impedance matching to a 100 volt speaker line. The

“ALERT” and “EVAC” Stage controls adjust the output Stage of each set of signals.

Short or open circuit speaker faults are detected by the fault monitoring circuitry and will result in the illumination of the FAULT indicator mounted on the front panel control module and “SPEAKER SHORT”

(red) or “SPEAKER OPEN” (yellow) LEDs on the main board.

Public Address

A microphone (Order Code 294-0001) is used to provide the public address capabilities.

EV40 Verbal Messaging

An optional verbal messaging PCB (Order Code 222-0013) is available and is mounted directly onto the main board.

INSTALLATION COMMISSIONING & OPERATION

When the control switch is in;

AUTOMATIC - occupant warning signals and if applicable verbal messaging is under the control of the microprocessor and outputted to the speaker system when it receives a “warning system” signal from the

FACP.

ISOLATE

– the occupant warning system is isolated from the FACP “warning system” signal and even if the signal is present there will be no output.

PUBLIC ADDRESS

– the occupant warning system can be used locally as a PA system.

MANUAL EVACUATION

– the occupant warning signal/s will be transmitted over the system.

Indicators

LINE FAULT

- In the event of an open or short circuit speaker line the LINE FAULT indicator (yellow) will be illuminated

ISOLATED

- the LED will be illuminated (yellow) when the warning system is isolated

PEV: - PA + Evac

– must be inserted when a selector switch is connected.

PAU: - PA in Auto

– if inserted allows Mic 1 input (hand held microphone) to be used in “Auto”

(with no FACP alarm ) and paging in “Evac” mode.

PA2 CONT: - PA2 Control

– if inserted allows the PA2 input to also switch the Control Output.

M2 1milli volt: - if inserted enables a 1mV microphone input for Mic 2, not inserted enables the input for 100mV line level ( background music etc.)

HLI Interface Operation

The EV3000 Occupant Warning and Intercommunications System ( OWIS ) main central processing unit communicates via a RS485 bus with a Controller Interface Card ( CIC ) in an FACP.

A fault in the EV3000 will be indicated by the Master Control Panel which in turn initiates, via the Common

Fault Relay Board and Brigade PSU Monitor Board, a Warning System Fault indication on the FACP.
