APPENDIX C - TAS 2000 SLIM LINE AND MRK-1RK RETRO-FIT

There are two additional TAS 2000 Telephone Access models available. One is the TAS 2000 Slim Line which
provides all the same features as the TAS 2000 in a narrower mechanical box and the other is the TAS 2000 MRK
retro-fit version used to update existing telephone access equipment. The TAS 2000 Slim Line and the TAS 2000
retro-fit are able to handle up to 750 residents whereas the Standard TAS 2000 is able to have a database of up to
2250 residents.
TAS 2000 MRK-1RK RETRO-FIT TELEPHONE ACCESS
The Mircom TAS 2000 MRK-1RK Retro-fit Telephone Access Unit is designed to provide an easy flush replacement
of existing access equipment. The system provides back-lit display, a built-in Postal Lock micro switch and tamper
proof screws. The MRK-1RK is a NSL (No Subscriber Line) system which has all the same features as the TAS-
2000 including ring pattern selection, keyless code entry and an event log. The Mircom MRK-1RK is also available
as a scrolling (display) under the model MRK-1RKS.
This retrofit version is wired using the existing wires. It requires NSL Relay Cabinets, relay cards, Elevator
Cabinets ( if required) and transformers. The dimensions are different than the TAS-2000 and the Thermostat
Heater Kit is the TH-102. See below for mounting instructions and installation of the thermostat.
TH-102 HEATER INSTALLATION FOR THE MRK-1RK RETRO-FIT
Use the two #6 Hex nuts to
screw the TH-102 Heater into place as shown in diagram above. The 24VAC is connected to the terminals on the
TH-102 using 18 AWG twisted pair wire.
TAS 2000 MRK-1RK RETRO-FIT LOBBY WIRING
The TAS 2000 MRK-1RK Retro-fit lobby panel is wired in the same manner as the TAS 2000 Slim Line. To wire the
retro-fit model use the information given in the following diagrams. The retro-fit lobby board and the slim line lobby
board have the same layout. All other wiring, i.e. to the NSL Units, is as shown in this manual in the appropriate
