The basic TMA package (Model 12509-042) includes a single line transceiver for polling a single
telephone at a time. Each telephone requires approximately 90 seconds to relay its health status to TMA.
Use multiple transceivers to poll multiple telephones simultaneously in larger systems. The Model
12509-043 TMA Expansion Kit is available and is required for each additional connected telephone line,
with a maximum of eight lines allowed. This allows a maximum of eight telephones to be polled
simultaneously. A dedicated PC is strongly recommended for TMA operation.
A dedicated telephone line per RED ALERT
®
telephone is required when using TMA in its typical
polling
operation. RED ALERT
®
telephones can share a telephone line; however, if two or more
telephones are put into use simultaneously, the line current could drop sufficiently to disconnect the
telephone call. This will depend on the line current, the length of the cable run, and the condition of the
telephone cable. Telephones must be scheduled to
call-in
instead of being polled by TMA when sharing a
telephone line. A shared telephone line between RED ALERT
®
telephones is not recommended.
Auto-dial maintenance calls should be scheduled in TMA to alert maintenance personnel of any unusual
sensor or fault conditions that exist. RED ALERT
®
telephones can also be programmed to generate an
auto-dial maintenance call when certain sensor events occur. Access to the RED ALERT
®
telephone’s
settings is restricted using a maintenance access PIN that should only be disclosed to trained maintenance
personnel.
