Positron has introduced the Power/Access plug-in card, model number 721123.

This new card provides -48Vdc power to any TeleLite shelf from a 120Vac or -129Vdc power source (input). It offers the same local and remote alarms connectivity as the Access card as well as a new power alarm connectivity feature, which enables a connection to an alarm panel for remote monitoring of power failures relating to the shelf.
