INTERLOCK WITH OTHER OPERATORS: (REQUIRES THE K1 RELAY OPTION)
VERSIONS 5.20 OR GREATER NOW HAVE THE ABILITY TO ALLOW THE MEGA-ARM TO MONITOR FOR THE FULL OPEN
POSITION OF A SLIDE, SWING, VERTICAL PIVOT, ROLL UP OR OVERHEAD OPERATOR AS WELL AS THE DOWN POSITION
OF MOTORIZED TRAFFIC TEETH (MTC-31) AND RAISE THE ARM ONCE FULLY OPEN.
This new feature will allow a logical interface between the MEGA ARM barrier gate and a swing, slide, etc... gate operator (or MTC-31).
All that is required is 4 wires between the Mega Arm barrier gate and the other operator. It will be necessary to have one set of
dedicated/isolated dry contacts-{C. & N.C.} COMMON & NORMALLY CLOSED be available at the other operators OPEN LIMIT
SWITCH. Most units will require that this EXTRA limit switch be added to their open limit switch assembly.
OPERATION: A one second pulse from access control device to the MEGA ARM will energize its K1 relay sending an open signal to
the other operator causing it to open, however, the MEGA ARM's boom will not raise yet. When the other operator reaches its full open
limit switch, this will open the COMMON & NORMALLY CLOSED contact on the EXTRA open limit switch. This will allow the original
signal from your access control device (that was stored in memory) to now raise the gate arm. As long as the other operator is in the full
open position, any additional open pulse sent will in turn energize the MEGA ARM's K1 relay to send another open signal to the other
operator as well as cause the arm to raise again if it has closed via a car crossing the MEGA ARM's close loop.
WIRING: Run 2 wires from the other operators isolated common & normally closed contacts of its open limit switch to the MEGA
ARM J5#8 and one of the commons J5 , #9-12. Next run 2 wires from the MEGA ARMs K1 relay (common & normally open) to the
other operators common and open input. (WARNING: max of 30 VOLTS @ .5 AMPS THROUGH RELAY). J5 #8 was the unused
SHADOW LOOP input on the MEGA ARM. Note: A separate open device (24 hour timer, toggle switch) can be run to the other operator
to control it without raising the gate arm. Tampering with the other operators safety loops, safety edges and reverse sensors WILL NOT
cause the arm to raise if one tripped. The arm will only raise if an intended open signal was sent to the MEGA ARM.
NOTE: FOR MOTORIZED TEETH, VERTICAL PIVOT OR OVERHEAD OPERATOR, LEAVE S1-6, S1-8 OFF (THIS WILL KEEP THE
K1 RELAY LATCHED UNTIL THE ARM REACHES THE DOWN POSITION. THIS WILL KEEP THE OTHER GATE OPERATOR
LOCKED OPEN OR TEETH LOCKED DOWN UNTIL THE ARM CLOSES COMPLETELY). NOTE: IN THIS MODE IF THE ARM
SENSES AN IMPACT, THE K1 RELAY WILL STAY ENERGIZED HOLDING OPEN (OR TEETH DOWN) THE OTHER OPERATOR
UNTIL THE ARM TIMES OUT AND CLOSES.
ACCESS
DEVICE
S1, 6 &8 (ON) = K1 RELAY PULSE ONLY. S1, 6 & 8 (OFF) = K1 RELAY LATCH ONLY.
INTER-LOCK TWO MEGA ARMS WITH "MEMORY": REQUIRES THE K1 RELAY OPTION
NOTE: (5.20 or greater) can be used when you have two entry gates that you want to INTER-LOCK with each other. This is when you
can only have ONE gate raised at a time (bottle neck or gates at a cross street). In this case, which ever one raises first will get first
priority, while if the other gets an open signal, it will be HELD IN MEMORY, then raise once the first gate closes. This will work if either
gate has a telephone entry unit or access device (AVI ,prox , etc...). Connect the K1 relay C & N.O. of each gate to the SHADOW
LOOP J5 #8 input & common of the other . (Leave S1-6 & 8 OFF to allow relay to stay latched).
