WIRING UP THE UNIT
24V Output Connections:
Power 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).
24VDC input is provided via 2.1mm DC jack.
Microphone Input
Microphone input is provided by 3 pin euro block
connection.
Remote Contacts
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.
Evac Contacts: These contacts are for remote triggering
of the evac tone. Connecting these terminals together
will activate the evac tone.
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.
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.
Audio Output:
DIP Switches:
This output consists of stereo RCA sockets with an
output of 0dBm into a 600Ω input. This is suitable for
most PA amplifier auxiliary inputs.
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.

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: 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

INSTRUCTIONS FOR USE
Mains Power Switch. This switches 24V DC power to the
unit on and off.
7. Audio Output
8. Volume Level Chime/Tones/Voiceover
9. Message Record Button
When the alert is triggered, the unit will sound the alert
tone for a preset time, then the evac tone for four cycles,
sound the voice over message twice (if selected on), then
sound the evac tone for four cycles, and continue in this
evac/voice over sequence.
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.
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.
LED Power Indicator. This LED will be lit when the unit
is being powered.
Alert Tone: If the alert tone is triggered the unit will
sound for a preset time, and will change to the evacuation
mode. This preset time is determined by the internal DIP
switch settings (see Internal Settings). The evacuation tone
will continue to sound until the panel has been cancelled.
Once the alert tone has been triggered, triggering the evac
contact will automatically change the unit from alert to
evac mode.
