A 4505B 7 Day Timer With Lockdown & Fire Alarm Control
Overview
This weekly timer with lockdown and fire alarm control is housed in a
convenient 1RU rack mount chassis. A total of 50 “event” switching times are
available through the timing functions. Each event can be set to turn on any
single day of the week or on multiple days, from 1 sec up to 24 hours. When a
timing event is activated, an MP3 audio file will be played and output through
the dual RCA line level output.
There are fourteen MP3 playback options for the timing events, which include
the Bell, Prebell, Music and folders 5-15. A Micro SD card which is supplied,
houses all the MP3 files to be played as well as storing all the timing events
(Note: The audio files must be in MP3 format). The timing events can be
programmed via supplied PC software.
The timing events can also be programmed to only trigger the Bell 24V out (and
in turn the common 24V Out), with no audio output. This is activated by
setting the output to the “relay” option in the programming setup.
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. Lockdown & fire switches on the front
of the unit are fitted with safety covers to prevent accidental operation.
Warnings, bell and cancel function are triggered by the front switches, 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 lockdown and fire tones are stored on a Micro
SD card in MP3 format (emergency tones which conform to AS1670.4 are supplied)
to allow the user to provide any tones they require. The Fire mode has a voice
over option for the playback of a fire message after every playback of the
fire tone. The voice over message is also stored on the SD card and is DIP
switch enabled. The lockdown mode has a voice over option for the playback of
a lockdown message after every playback of the lockdown tone. The voice over
message is also stored on the SD card and is DIP switch enabled.
