KT-PC4216 - 16-Zone Output Expansion Module
KT-PC4216 Introduction
The KT-PC4216 module is an open-collector to 12 VDC 16-zone output
module. Can be used for elevator access control (may require additional
hardware).
KT-PC4216 Specifications
•
16-output low current module, 12 VDC, 50 mA max. each, power drawn
from Combus (since Combus can handle a maximum of 500 mA, a KT-
PC4204 module in “repower” mode can be used to increase the current of
the Combus of 1A).
•
Connects to KT-315 via 4-wire Combus
•
Nominal current draw of 15 mA
•
Tamper contact input
•
Can be used for elevator control
Unpacking the KT-PC4216
The KT-PC4216 package should include the following parts:
•
One KT-PC4216 circuit board
•
4 plastic standoffs
Mounting the KT-PC4216
The KT-PC4216 should be located inside a compatible cabinet (part no. KT-
4501CAB), mounted in a dry, secure location. It should be placed at a
convenient distance from the connected devices. Perform the following steps
to mount the units:
1. Press the four plastic standoffs through the mounting holes at the back of
the cabinet.
2. Secure the cabinet to the wall in the desired location. Use appropriate wall
anchors when securing the cabinet to drywall, plaster, concrete, brick or other surfaces.
3. Press the circuit board into the plastic standoffs to secure the module to the cabinet.
NOTE:
Wiring may be started once the unit is mounted.
Installation and Wiring
Before beginning to wire the unit, ensure that all power (AC transformer and battery) is disconnected from the controller.
Perform the following steps to complete wiring:
1. Connect the four Combus wires to the KT-PC4216. Connect the Red, Black, Yellow and Green Combus wires to the RED,
BLK, YEL and GRN terminals, respectively.
2. Complete all output wiring as illustrated on the next page.
3. Connect the external tamper switch, if used.
NOTE:
Power is drawn from
the Combus. May
require a KT-PC4204
power supply module
if drawing too much
power from the
Combus.
