PN-VMBKP-ed1-A4
Overview of connection terminals
Velbus connections (required) (-, +, L, H)
The connector for the Velbus bus cable. The
–
and + connections are for the 15±3VDC power supply. The L and H
connections are for the Velbus data communication.
Next to the Velbus connection
terminal there is also a Velbus CAN terminator switch, marked “TERM”. According to the
position of the VMBKP in the Velbus installation, this terminator may need to be closed. Please consult the Velbus
Installation Guides on
for more information on the Velbus system and on the CAN terminators.
Other connections (optional/advanced)
ALM O/P (Alarm Output)
An NPN transistor open collector output with a maximum power rating of 24VDC/100mA sink. It is equivalent to an N.O.
(Normally Open) terminal referring to ground. It is designed for triggering a N.O. protection zone of an alarm system. It
can also be used to drive a low power device, such as a relay or a low power control input for other equipment.
DUR O/P (Duress Output)
An NPN transistor open collector output with a maximum power rating of 24VDC/100mA sink. It is equivalent to an N.O.
(Normally Open) terminal switching to (-) ground after the Duress Code is entered. It can be used e.g. to trigger an alarm
zone of a security system or turn on a buzzer to notify a guard.
O/P 1 INH (User Group 1 Inhibit Control Input
–
Normally Open)
A Normally Open (N.O.) sensing input point for controlling User group 1. With this terminal connecting to (-) ground, the
Egress Button and the PINs and Cards for User Group 1 are all disabled.
NOTES:
•
This inhibit function does not overrule the Duress Codes and the Super User Codes. They are always valid.
•
This inhibit function is a hardware feature of the keypad, not to be confused with the VelbusLink “inhibit”
actions. These function independently of each other.
EG IN (Egress Input)
A Normally Open (N.O.) input terminal referring to (-) ground. A normally open button connected to this input can
activate the User Group 1 channel just like using Codes/Cards.
An egress button is usually installed
inside
the house near the door. More than one egress button can be connected in
parallel to this terminal. Leave this terminal open if not used.
See “
A unique feature of the keypad
32 for more information about the Egress Button
with programmable features.
(-) GND (Common ground)
A grounding point that is common with the
–
input of the Velbus bus connection.
DOOR SENS (Door Position Sensing Input
–
Normally Closed)
A Normally Closed (N.C.) sensing point referring to (-) ground. By connecting a magnetic door sensor to this input, it
monitors the open or closed status of the door. Connect this input with a wire to (-) ground if not used (factory default).
