School Lockdown Controller A4595A

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 period bell plus a standby, lockdown and all clear tones. These can be activated by the switches on the front panel, by the remote closing contact triggers on the rear of the unit or by the optional wall plate (A 4598) or paging console (A 4660).

A pre bell/chime/tone is also included which can only be triggered by the closing contact on the rear of the unit. All tones are stored on an SD card in MP3 format. Using MP3 files gives the user complete control over the sounds played for each tone. This could be music, a pre-recorded tone or speech etc. The standby and lockdown tones can also be set to loop/repeat via external DIP switches. The order of priority from highest to lowest is all clear, lockdown, standby, bell and pre-bell. If the period bell is activated the period bell switch on the front of the unit will illuminate until the tone finishes. If the standby or lockdown tone is activated, the corresponding switch on the front of the unit will illuminate until the tone finishes. After this, the switch will continue to illuminate until the lockdown overrides the standby condition or the all clear condition is activated. If the all clear tone is activated the all clear switch will illuminate until the tone finishes.

If any wall plates or paging consoles are connected the switches or LEDs on these units will illuminate accordingly. 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 (pre-bell, period bell, standby, lockdown and all clear). Connections to the paging consoles and wall plates are made via Cat5e cabling. Up to four paging consoles or 16 remote wall plates can be connected at one time. A standard line level output is provided for connection to the schools PA system.

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