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.
