The alarm cable (RS-232 connector) was found unattached and laying on the floor behind the freezer. (Note: This provides a remote alarm to BNL Bldg 600 Chilled Water Facility. This antiquated alarm is of a "normally closed" design and will identify power failure and/or over temperature conditions, (but will not alarm when disconnected). If the alarm cable had been attached (or if the system had identified and alarmed when it was unattached), then monitoring personnel at the Chilled Water Facility would have been alerted and responded. Research personnel would have transferred the samples to other locations to prevent them from thawing.
