Installation Instructions
Terminal Descriptions (Cont)
J7
OPN
Open
Passage
Connection for Fire Alarm System or
placing turnstile in “OPEN” status -
Clockwise Direction
0VDC,
18mA
Providing a continuous dry contact at this terminal places
the turnstile in an “OPEN” mode. Typically, this terminal
is used to connect the fire alarm system (normally open
type) when the turnstile is configured for clockwise
rotation in the exit direction (default).
J7
CNT
Passage
Count
Confirmation signal upon turnstile rotation
- Clockwise Direction
0VDC,
18mA
Outputs a dry contact upon rotation of the turnstile.
This feature can be used to output a “count” signal to
an external system such as Alvarado’s GateWatch or
to provide feedback to the access control system that a
turnstile rotation has taken place.
J7
COM
Passage
Count
Confirmation signal upon turnstile rotation -
Clockwise Direction
0VDC,
18mA
Common dry contact connection for CNT count signal
output. See J3 CNT description.
SW6
CW Entry
Activation
Test Button
Allows user to test turnstile activation -
Clockwise Direction
N/A
Depressing button simulates input to J7 ACC, “Entry
Accept”. If turnstile solenoid “fires” after depressing
button AND re-locks after a single rotation of the Roto or
upon time out, the turnstile is functioning correctly in the
Clockwise Direction.
J2
CCW-CNT Output of contact closure upon turnstile
rotation – Counter Clockwise Direction
1.06VDC,
5µA
Single throw, relay output for connection to Alvarado
battery powered, digital counter.
J8
CW-CNT
Output of contact closure upon turnstile
rotation - Clockwise Direction
1.06VDC,
5µA
Single throw, relay output for connection to Alvarado
battery powered, digital counter.
J5
Optical
Sensors
Connection for sensors
3.3VDC,
16.5mA
The ATC uses input from the sensors to monitor
rotation of the Roto.
J11
CNT-
RESET
Connection for counter reset key switch
1.06VDC,
5µA
N.O. contact connection if counter wires are attached
to J2 and/or J8 connections. A 2-position electrical
key switch is connected here to provide a reset to the
individual counters.
SW3

counters
Local Battery Counter Reset Switch
N/A
If counter wires are attached to the board (J2 and J8),
depressing this button will reset the counters. If two
counters are installed and wired, both counters will be
reset.
J19
EL Light
Boards
Connector
Connection for EL light boards
12VDC,
242mA
If red/green status lights are used, the green light
signifies that the turnstile is ready to accept an
activation for the direction shown. When the CLS
and GND connection is closed, the red light will be
illuminated and signifies that the turnstile will not accept
an activation. Refer to description for CLS on J3 and
J7.
J4
Power
Input
Connection for low-voltage power
13.5VAC,
4.33A
The ATC accepts 10VAC or 13.5VDC power. If primary
power is not run to the turnstile, low-voltage power
is connected here. The green ground wire must be
grounded to the chassis.

Providing a continuous dry contact at this terminal places
the turnstile in a locked “CLOSED” mode. This mode
overrides the access control system operation. If status
lights are installed (Location J19) the red light will be
illuminated continuously.
