LIM4
Door Controller for Card Access Control
Borer’s LIM4 is a single door access controller for use in on-line access control applications. The LIM4 provides full on-line and off-line validation and decision making capabilities at the point of entry.
It supports most third party card reader interfaces, including:
Wiegand
Magnetic stripe (clock and data)
Bar code
Dallas iButton
Plus many proximity and biometric formats
The LIM4 was developed using ‘clean design’ principles to minimise device mass and reduce energy consumption. Unnecessary components have been eliminated. This together with a low energy profile delivers a ‘cleaner, leaner and greener’ solution, reducing lifetime operating costs.
Featues:
Dual database of cardholders and access rights held at every reader head, with fall back to the last known good database in the event of a data corruption or interruption during database download
Large integrated database with a total capacity of up to 120,000 cardholders / transactions
Two magnetically assisted Omron relays for energy efficient switching of electric release and local alarm / alarm shunt
Four supervised inputs for door monitor, request-to-exit, tamper and spare
Four state monitoring of inputs checking for short circuit, open circuit, normally open and normally closed
PIN keypad matrix interface
LCD display panel interface optional
Works with Borer Midspan Bridge technology which delivers power and data over a single CAT5e / 6 cable.
