Note: To comply with industry standards, this product is equipped with line seizure. Any time the system’s dialer
needs to communicate with the central station, it will not be possible to use any telephones that are on the
same line(s) as the system. Normally this condition will last approximately one minute, but under adverse
telephone conditions, could last for as long as 15 minutes.
