Redback® A 4595A School Lockdown Controller

1.0 OVERVIEW

1.1 INTRODUCTION

This lockdown controller complements the A 4565 Alert/Evac controller and is primarily aimed at schools which require a

lockdown warning facility. The controller has provision for a Pre-Bell and a Period Bell which are activated by the closing

contact triggers on the rear of the unit. Standby, Lock In, Lock Out and All Clear tones can be activated by the switches on

the front of the controller, or by the optional wall plates (A 4598) or paging consoles (A 4596).

The unit is powered from a 24V dc source (power supply included) and separate 24V dc switched outputs are supplied

for remote triggering (of sirens/strobes etc) for all tone conditions (Bell/Pre-bell, Standby, Lock In, Lock Out and All Clear).

There is also an Emergency 24V out which is activated on Standby, Lock In, Lock Out and All Clear conditions and when

emergency paging is active. A Common 24V Out is activated by any tone condition or by any paging state. Connections to

the paging consoles and wall plates are made via Cat5e cabling.

The audio output is typical 1V rms line level and is adjustable via a trimpot adjustment on the rear of the unit.

The lockdown unit can be connected to the A 4565 alert/evac controller if an EWIS system is also required and is made

with a dual RCA lead . The A 4565 will take priority over the A 4595A lockdown unit in the case of an emergency.

Redback® A 4595A School Lockdown Controller

2.0 OPERATION

2.1 LOCKDOWN MODES

The A 4595A Lockdown controller has four Lockdown Modes which are Standby, Lock In, Lock Out and All Clear.

Once a Lockdown mode is activated an MP3 audio le is played until the audio le nishes or the A 4595A changes mode.

The Audio Files can be an Alert or Evac tone, a piece of music or a recorded message, etc and are stored on the internal

SD Card (supplied). Audio les will be supplied to provide basic functionality but the installer will be required to copy their

own audio les onto the SD Card (See section 3.6 for more details).

• Standby Mode - This would typically be used to notify students and staff that there may be a possible situation in

the school grounds and to “Standby” for a possible Lock Down.

A music track which doesn’t cause panic but is known by the staff would be an appropriate

audio le to be played in this mode.

• Lock In Mode - This mode would be used to notify students and staff that there is a situation outside the school

class rooms but still in the school grounds (eg The School Oval) or maybe the hall ways.

Students and staff would be then required to lock themselves inside their class rooms.

A warning tone, maybe with a repeating message may be suitable.

• Lock Out Mode - This mode would be used to notify students and staff that there is a situation inside the school

buildings. Students and staff would be then required to remain outside their class rooms or

other school buildings, but remain in the school grounds. This may be applicable when students

are on a lunch break and are playing outside.

A warning tone, maybe with a repeating message may be suitable.

• All Clear Mode - This would notify students and staff that it is now safe and that the situation has been rectied.

A music track which is known by the staff would be an appropriate audio le to be played in this

mode.

The lockdown modes can be activated in a number of ways.

1) Pressing the buttons on the front of the A 4595A.

2) Activating the modes by the A 4598 optional remote plates (see section 4.3).

3) Activating the modes via the A 4596 optional paging microphones (see section 4.2).

2.2 FIRE TEST/FIRE ALARM

The A 4595A has two Fire Modes (Fire Test and Fire Alarm) which can only be triggered via the optional A 4597 Wall Plate.

Once a Fire mode is activated an MP3 audio le is played until the audio le nishes or the A 4595A changes mode.

The Audio Files can be an alarm tone, a piece of music or a recorded message, etc and are stored on the internal Micro

SD Card (supplied). Audio les will be supplied to provide basic functionality but the installer will be required to copy their

own audio les onto the Micro SD Card (See section 3.6 for more details).

2.3 PREBELL/BELL

As the A 4595A is aimed primarily at schools, a Prebell and Bell function have been included. These are triggered by

closing contact terminals on the rear of the unit and could be triggered by a timer such as the Altronics A 1709 Timer as

shown in gure 3.3. Once the Prebell or Bell mode is activated an MP3 audio le is played until the audio le nishes or

the A 4595A changes mode. (See section 3.4 for more details)

An indicator on the front of the unit will illuminate when the Prebell or Bell tone is active.

2.4 AUXILLIARY MP3 TRIGGERS

There may be times when extra tones or audio les are required to be played through the A 4595A. Examples might

include playing a message each week calling students to assembly. These are triggered by closing contact terminals on the

rear of the unit. Once the Aux MP3’s are activated an MP3 audio le is played until the audio le nishes or the A 4595A

changes mode. (See section 3.4 for more details)

An indicator on the front of the unit will illuminate when any of the Aux MP3 tones is active.

Redback® A 4595A School Lockdown Controller

2.5 PRIORITIES

The order of priority for the functions of the A 4595A are as follows.

1) Emergency paging (Via the optional A 4596 paging consoles)

2) Fire Alarm (Via optional A 4597 wall plate)

3) All Clear Mode, LockIn or Lockout Mode

4) Standby Mode

5) General paging (Via the optional A 4596 paging consoles)

6) Fire Test (via optional A 4597 wall plate), PreBell/Bell, AuxMP3-1, AuxMP3-2, AuxMP3-3

■Emergency Paging

Emergency paging via the optional A 4596 paging console, overrides all other functions of the A 4595A. If

emergency paging is activated by pressing the Emergency paging button on the paging console, and any of the

Standby, Lock In, Lock Out or All Clear modes (the four Lock Down modes) are triggered these will become active

once the emergency paging nishes.

If any of the Lock Down modes are already active and paging is initiated, it will override these modes, returning to

them once paging has nished. Note: To activate emergency paging while the unit is in any of the Lock down

modes, the emergency paging button doesn’t need to be pressed. It is simply a matter of using the paging toggle

switch to page.

■ Fire Alarm

This has the highest priority of all modes and can only be overridden by emergency paging.

The Fire Alarm can only be initiated by the Fire Alarm wall plate (A 4597).

■All Clear Mode ,Lock In or Lock Out Mode

The All Clear, Lock In and Lock Out modes all have the same priority, meaning that if one mode is active and the

other mode is triggered, the unit will switch over to the other mode. All three of these modes can be overridden

by emergency paging.

■Standby Mode

The standby mode has the lowest priority of the four Lock Down Modes but will override the Fire Test, Prebell/Bell

or the Aux MP3 tones.

■General Paging

General paging via the optional A 4596 paging console overrides the Fire Test, PreBell, Bell and AuxMP3-1 to Aux

MP3-3 triggers.

■Fire Test, PreBell/Bell Tone ,AuxMP3-1, AuxMP3-2, AuxMP3-3

These triggers have the lowest priority of all functons on the A 4595A are can be overridden by every other

function.

The Fire test can only be initiated by the Fire Test wall plate (A 4597).

3.0 SETUP GUIDE

3.1 POWER CONNECTIONS

A DC socket and a 2 way terminal have been provided for 24V DC input.

The DC socket is for connection of the supplied plugpack which comes with a standard 2.1mm jack connector.

The 2 way terminal is for connection of a backup power supply or battery.

www.altronics.com.auRedback® Proudly Made In Australia10

Redback® A 4595A School Lockdown Controller

3.2 AUDIO CONNECTIONS

Audio Output:

This output consists of stereo RCA sockets with an output of 0dBm into a 600Ω input. This is suitable for most PA

amplier auxiliary inputs. The output level is adjusted via the Master volume trimpot on the rear of the unit. The output

level of the MP3 audio les is adjusted via the MP3 level trimpot on the rear of the unit.

Fig 3.2

3.3 24V DC OUTPUT CONNECTIONS

There are seven sets of output terminals for the connection of 24V DC driven devices. E.g School Bell, warning strobes,

override relays in volume controls etc.

Each set of output terminals have a N/O (normally open), N/C (normally closed) and a ground connection. In this

conguration 24V appears between the N/O and ground terminals when this output is activated. When this output is not

active 24V appears between the N/C and ground terminals.

(NOTE: The maximum current draw per output is about 120 milliamps, so it is advisable to run external 24V DC relays

instead of trying to drive a 24V DC device directly from these outputs. See Fig 3.3 for an example of this).

Bell/Pre Bell 24V Out:

These contacts are for operating an external relay used to operate something like a school bell.

Fig 3.3 demonstrates an example of how to connect the A 4595A Lockdown Controller to the Altronics A 1708 timer to

trigger the schools Pre-Bell and Bell .

The Zone 1 closing contact of the timer is used to trigger the school Pre-bell contact and the Zone 2 closing contact is

used to trigger the school Bell. In the example shown the Bell/Pre Bell 24V Output is used to drive a 24V school Bell.

As the current draw of the Bell is more than 120mA a relay board is used to switch an external power supply. The

Altronics S 4444 24V Relay Board as shown below or the S 4455 12/24/48V Din Rail Relay box are inexpensive and easily

installed options designed for this purpose.

Standby 24V Out:

These contacts are for switched 24V outputs whenever the Standby mode is activated. These may be used to run

external systems such as strobes in unusually noisy environments or for hearing impaired students or staff. They may also

be used for the connection of override relays in remote volume controls. An override relay is necessary where

attenuators are used so that the audio is broadcast at full volume regardless of the volume setting on the individual vol-

ume control (attenuator).
