ID and siren
Warning!
Installation of intrusion detector inside the turnstile housing is not anticipated.
Intrusion detector is connected to contacts
Detector
,
GND
and
+12V
of connector block
XT1.L
of control board. Characteristics of input signals are indicated in sec. 5.2.5. Current
condition of intrusion detector is transmitted on relay output
DETECTOR
(contacts
Det Out
and
Common
of connector block
XT1.H
).
Siren is connected to contacts
Alarm 1
,
Alarm 2
and
GND
and
+12V
of connector block
XT1.H.
Characteristics of relay output signals
ALARM
are indicated in sec. 5.4.1.
Output activation
ALARM
takes place, if activation of input
Detector
takes place with a
blocked rotating mechanism of the turnstile (command
«Passage denial»
or
«Both
directions closed»
is issued), i.e. control signal comes from the intrusion detector. Output
ALARM
gets stabilized in 5 seconds after activation or in case of any incoming control
command.
Note:
Control signal from intrusion detector doesn’t lead to
ALARM
output activation
,
if the
rotating mechanism of the turnstile is blocked in one of directions or was blocked
less than 3 seconds ago.
5.4.3
Remote indicators
Remote indication blocks for corresponding passage directions is connected to outputs
Light A
and
Light B.
Outputs are provided with the complete group of contacts: normally
opened
NO
, normally closed
NC
and common
C
. Connection to the outputs is done
correspondingly through connector blocks
XT4
and
XT5
.
If the passage in direction A/B is permitted, relay of corresponding passage direction
Light A
/
Light B
gets activated (its winding gets energized), if the passage is denied – it
gets stabilized. Relay winding energizing can be identified by lighting up of corresponding
red LED, installed on control board near the corresponding relay.
Output cascades for the “Light A” and the “Light B” relays are nonbridging relay contacts
(Fig. 10) with the following signal characteristics:
maximum switched voltage
.......................................................................... 30 VDC
maximum switched voltage
........................................................................... 42 VAC
maximum switched AC/DC ................................................................................... 3 A
closed contact resistance
.................................................... no more than 0.15 Ohm
