Wiring Up The Unit

Power Connections

24VDC input is provided via 2.1mm DC jack.

Microphone Input

Microphone input is provided by 3 pin euro block connection.

Remote Contacts (Rear of unit)

Provision has been made for four remote contacts on the back of the unit. These are all activated by closing the corresponding contact

(connecting the terminals together).

Alert contact: These contacts are for remote triggering of the alert tone ie: for use with Fire Indicator Boards, break glass alarms etc.

These contacts can be set to either continuous or momentary operation via dip switch 5. ( refer Table 2)

In continous mode the alert tone will continue while the alert contact is triggered.

In momentary mode the alert tone will continue to sound after a momentary trigger of the alert contact.

Evac Contacts: These contacts are for remote triggering of the evac tone. Connecting these terminals together will activate the evac tone. These contacts can be set to either continuous or momentary operation via dip switch 5. ( refer Table 2)

In continous mode the evacuation tone will continue while the evac contact is triggered.

In momentary mode the evacuation tone will continue to sound after a momentary trigger of the evac contact.

Cancel contact: These contacts are for remote cancelling of the alert or evac tones.

The alert, evac and cancel remote contacts can be triggered with the

Altronics A 2078A remote wall plate (see figure 3 - typical wiring diagram) or any closing contact.

Bell Chime Contacts: These contacts are for remote triggering of the bell chime sound. This bell chime can be used for signalling lunch breaks, start of classes, and can be triggered from a time clock or similar device. For details of this, see Installation instructions for the bell tone. Connecting these terminals will activate the bell.

Audio Output:

This output consists of stereo RCA sockets with an output of 0dBm into a 600

Ω input. This is suitable for most PA amplifier auxiliary inputs.

24V Output Connections:

Switched 24V Out: These contacts are for connection of override relays in remote volume controls. An override relay is necessary where attenuators are used so that the alert tone, evac tone or message is broadcast at full volume regardless of the volume setting on the individual volume control (attenuator).

The override relay can be set to “NORMAL” mode when connection is made between the N/O (normally open) contact and the GND connection. In this configuration 24V appears when any of the alert tone, evac tone, voice over message or paging functions are activated.

The override relay can be set to “FAILSAFE” mode when connection is made between the N/C (normally closed) contact and the GND connection. In this configuration 24V is removed when any of the alert tone, evac tone, voice over message or paging functions are activated.

Alert/Evac 24V Out: These contacts are for switched 24V outputs whenever the alert or evac tones are activated. These may be used to run external systems such as strobes in unusually noisy environments.

These operate in the same manner as the switched 24V out contacts ie: connection between the N/O contact and the GND contact will operate in NORMAL mode and connection between the N/C contact and the GND will operate in FAILSAFE mode.

Bell 24V Out: These contacts are for operating an external relay used to operate something like a lunch bell etc.

These operate in the same manner as the switched 24V out contacts ie: connection between the N/O contact and the GND contact will operate in NORMAL mode and connection between the N/C contact and GND will operate in FAILSAFE mode.

DIP Switches:

Switches 1-4 Evacuation Timer Settings: These switches control the time period before the unit switches from the alert to the evac tone

(rear contacts only). This time period can be switched from 30s to 7.5

minutes in 30s increments. See table 1 for more information. Factory preset is 30s.

Switch 5: DIP switch 5 is used to set the ‘Alert and Evac’ contacts to momentary or alternate (See ‘Remote Contacts’ on page 2).

Switch 6 Voice Over Setting: DIP switch 6 is used to configure the voice over message.

OFF: Voice over will not play during the evac cycle

ON: Voice over will play during the evac cycle.

Switch 7 Bell Setting:

DIP switch 7 sets the bell to either continuous or momentary mode.

This is regardless of the bell being activated via the front bell switch or the rear bell contact.

In continuous operation the bell will sound for as long as the bell switch or rear contact is triggered.

In momentary operation the bell will sound for only a short period regardless of how long the bell is triggered.

OFF: Latched/Continuous operation

ON: Momentary operation

Switch 8 Bell Output Setting: DIP switch 8 sets the bell output to either a continuous or repeating “bong” tone.

OFF: Single continuous tone

ON: Repeating “bong” tone

Record Button: This button is used to activate recording mode for voice over message.

Alert/Evac Switches (Front Panel):

The alert and Evac switches on the front of the unit both work in momentary mode. ie. The alert tone will continue to sound after the alert switch is momentarily pressed and the evac tone will continue to sound after the evac switch is momentarily pressed. There is no automatic alert to evac switch-over option associated with the front panel switches.

Note 1: The tone that is being sounded (ie alert, evac, bell) will be indicated by the illumination of the relevant front panel indicator.

Note 2: To cancel a tone either use the remote cancel contacts or the front cancel button. Note the cancel button will need to be depressed for 2 seconds. This is to prevent accidental cancelling of a tone.

Rear Panel Volume Controls:

Tones: This sets the output level of the alert & evac tones.

Chime: This sets the output level of the bell.

V/over: This sets the output level of the message voice over.

Instructions for Use

Mains Power Switch. This switches 24V DC power to the unit on and off.

LED Power Indicator. This LED will be lit when the unit is being powered.

Alert/Evac Tones: If the alert tone is triggered via the rear contacts and is set to continue the alert tone will sound for a preset time determined by DIP switches 1-4 (see Table 1). After this preset time the unit will automatically switch over to the evacuation tone. The unit will sound the evac tone for four cycles, sound the voice over message twice (if selected “on” via dip switch 6), then sound the evac tone for four cycles, and continue in this evac/voice over sequence until the tone is cancelled. The tone can be cancelled by triggering the cancel trigger on the rear of the unit or by pressing the cancel switch on the front of the unit.

Recording of Voice Over Message

1. Connect a microphone to the 3 pin euro block on the rear of the unit.

2. Hold down the record button on the rear of the unit. Recording will start when the button is pressed and held. Recording will continue until the button is released. The recorded message will play back when the record button is released.

3. To re-record the message simply follow repeat step 2.
