7 Day Timer With Lockdown & Fire Alarm Control:

A timed audio announcement, lockdown and fire alarm controller all housed in a convenient 1RU rack mount chassis. For scheduled announcements a total of 200 “event” switching times are available through the timing functions. Each event can be set to turn on from 1 sec up to 24 hours. When a timing event is activated, an MP3 audio file will be played with 99 playback folders to choose from, which include bell, prebell, music and folders 5-99 on the included micro SD card. If more than one MP3 is in a folder the MP3 will be random played. Timing events can be programmed on the unit or with included PC software. The timing events can also be programmed to only trigger the Bell 24V out (and the common 24V out), with no audio output.

The lockdown/fire controller is designed around industry standard building emergency requirements. When connected to a paging system amplifier, building occupants can be alerted and/or evacuated in the event of an emergency e.g. fire, gas leak, bomb scare, earthquake.

The lockdown, fire, bell tones and cancel function are triggered by the front switches, external wall plates (see below) or by the rear terminal contacts for remote activation. Switched 24V DC Out connections are provided for bell, lockdown, fire or a common out. These contacts are for connection of override relays in remote volume controls, warning strobes, bells etc.

The units timer and bell times can be remotely managed over a local area network (LAN) or virtual private network (VPN) using A 4498 ethernet adaptor pack.
