Keri's Entraguard Silver telephone entry unit provides 750 tenant capacity with a large-font, 4-line display in an attractive housing that can also contain a PXL-500 Tiger Controller and an SB-593 Satellite Expansion Board for up to two doors of built-in card access. Like the Entraguard Titanium and Entraguard Platinum, this new unit provides the best telephone entry/access control marriage available by letting the Entraguard function as a node on a PXL controller network and putting both functions under the acclaimed Doors software umbrella.
