1.1 LP4502 Intelligent controller with two reader interfaces
The LP4502 intelligent controller provides decision making, event reporting, and database storage for the
HID Mercury hardware platform. Two reader interfaces provide control for two doors.
Host communication is via the on-board 10Base T/100Base-TX Ethernet port, or the Micro USB port (2.0)
with an optional Micro USB to Ethernet adapter.
Two physical barriers can be controlled with the LP4502. Each reader port can accommodate a read-head
that utilizes TTL (D1/D0, Clock/Data), F/2F or 2-wire RS-485 electrical signaling (OSDP reader for example)
and also provides tri-state LED control and buzzer control (one wire LED mode only).
Four Form-C relay outputs are provided for door strike control or alarm signaling.
Eight inputs are provided for monitoring the door contacts, exit push buttons, and alarm contacts. Input
circuits can be configured as unsupervised or supervised.
The LP4502 requires 12 to 24 V DC for power.
