A portable fire detector and alarm system includes a rechargeable battery power supply and circuitry that monitors a string of up to forty smoke detectors and signals a telephone auto-dialer and prerecorded message unit whenever an alarm occurs. The distal end of the detector line is fed back to the monitor which then detects any loss of continuity in the lines or input AC power and then signals a trouble signal through the auto-dialer.
Server room fire suppression technology has been around for as long as there have been server rooms. Most systems use Halon, even though it has been shown to be environmentally unfriendly (ozone depleting) and unsafe for humans. I recently found a new kind of fire suppression system and am contemplating installing it in my server room. Have you heard of it?
