dormakaba Canada Inc. RAC5 MFC Installation Guide – PK3738 | 12
The tamper alarm switch’s polarity is such that when the door is
closed, the switch itself is also in a closed state. Ensure that the
wiring to the premise alarm system is done accordingly to
prevent false alarms.
4.
Wire relay expansion board outputs. Refer to Annex B for sample wiring diagram.
The relay expansion board provides 8 relay contacts for wiring and control of relay-enabled elevator. The
board only provides normally open or normally closed dry contacts, so no power is provided by the board.
As wiring of relay-controller equipment may vary between products, please refer to the product
manufacturer’s instruction booklet.
NOTE:
Refer to Annex B, Figure 8 for specific relay expansion board bypass switches.
•
If bypass switches are ON, the relays are bypassed and the green LED associated with that relay
is turned ON
•
If bypass switches are OFF, the controller PCB can activate the relays. The associated LEDs turn
ON during relay activation
•
When the power of the RAC5 MFC is too low (power failure), the controller PCB stops
functioning and the relays on the controller PCB or the expansion board will return to their
normal state. The normal state is defined as relays OFF. Any peripheral connected to the relays
will then be either in a normally open (NO) or normally closed (NC) state, depending on the
wiring
5.
Install elevator controller.
Each Expansion board contains 8 dry relay contacts. Up to 8 expansion boards can be used for total
control of 64 common areas. The relay outputs are at the wiring input of each three-terminal connector
(NO, COM, NC) on the expansion PCB as well as being indicated on the label on the inside of the door.
Several floors can be controlled by one relay (one common area).
The relays in the RAC5 MFC are UL rated and are capable of a maximum switching of 30 VDC @ 1A. For
time duration of relay state change, please refer to Annex B, Figure 8.
6.
Connect the power adapter.
NOTE:
Dependent on the countries’ electrical power requirements, follow the directions below for the
power adapter required. Refer to Annex B, Figure 8 for detailed wiring.
a)
International Power Adapter
i.
Attach the appropriate AC outlet prong to the power adapter
ii.
Route the power adaptor wires into the enclosure and secure the wire (recommended
with tie wraps)
iii.
From the inside of the enclosure, crimp the fork terminals supplied in the hardware bad
to the end of each wire
iv.
Connect the fork-terminated wires to the power supply input as shown in Annex B,
Figure 8
b)
North America Power Adapter
i.
From the inside of the enclosure, connect one end of the fork-terminated wires to the
power supply inputs as shown in Annex B, Figure 8
