The VISTA Gateway Module (VGM) provides an interface between
ADEMCO’s VISTA fire/burglary alarm system and ADEMCO’s PassPoint Access Control
System.
Cross-functional user requirements such as card swipe to
arm/disarm now become a simple reality. VGM by itself provides a Dialer for your
PassPoint system to send Contact ID information to a central station.
Features
- 8- bit microprocessor.
- EEPROM based configuration storage.
- Echelon Network interface implemented with an Echelon transceiver.
- An ADEMCO Expanded Console Protocol (ECP) port consisting of a four wire
interconnect: power, ground, data transmit, and data receive.
- An ADEMCO Contact ID Dialer interface uses the ADEMCO Contact ID report
format to communicate with a central station.
- VGM allows existing central station automation equipment to accept and
recognize access control related events and differentiate them from burglar
and fire alarm activities.
- VGM accepts power from both VISTA panels and PassPoint systems so that in
the event of a power loss on either system, the other can operate the VGM
unit.
Applications
Once the appropriate configuration information has been
transferred from the PassPoint’s Main Logic Board (MLB) to the VGM, the VGM
passes the messages as indicated by the configuration from the MLB to the VISTA
and from the VISTA to the MLB. It keeps a copy of its configuration in a small
on board serial EEPROM.
Installation
The VGM obtains its power from the LOCAL power output
connection of its associated Access Control System Power Supply (ACS PS) when
mounted in a cabinet with a dedicated ACS PS. When mounted in a cabinet along
with an MLB or the PassPoint Door Control Module (DCM), it obtains its power
from the ACS PS REMOTE power output. The VGM requires 10.5-14V DC @ 100mA. The
VGM can also connect to a VISTA keypad power source. |
