ENERAL NFORMATION
The CKM-MR51E reader interface provides a network connected, single door
with paired reader, PoE based solution to the OEM integrator for interfacing
TTL, Wiegand, or RS-485 type readers to door hardware. The onboard twisted
pair Ethernet jack with PoE support enables easy installation.
N : For UL installations, PoE powered devices shall not be used; power for
OTE
these devices must be provided by a UL 294 listed, power limited source
(12 VDC).
One physical barrier can be controlled with the CKM-MR51E, using single or
paired readers. The first reader port can accommodate a read head that utilizes
Wiegand, magnetic stripe, or two-wire RS-485 electrical signaling standards;
one- or two-wire LED controls; and buzzer control (one-wire LED mode only).
The second reader port can accommodate a read head that utilizes Wiegand or
magnetic stripe signaling; one- or two-wire LED controls; and buzzer control
(one-wire LED mode only). Two Form-C relay outputs may be used for door
strike control or alarm signaling. The relay contacts are rated at 5 A at
30 VAC/DC, dry contact configuration. Four inputs are provided for
monitoring the door contacts, exit push buttons, and alarm contacts. The
CKM-MR51E requires power from PoE or local 12 VDC. The CKM-MR51E
may be mounted in a three-gang switch box.
