Overview This document is designed to explain the configuration and implementation of the manual acknowledgment of the duress alarm. In normal condition, RST410 uses the auto acknowledgment method for duress. When the duress is triggered from the Pendent, the gateway will send an auto response to the Pendent to give user acknowledgment of the duress. However it is possible to configure the gateway to provide acknowledgment to Pendent only upon external input. This document explains the commands and wiring to use the manual acknowledgment method. www.beamcommunications.com...
Configuration The Gateway supports AT style commands (AT^) for configuration. These commands can be entered using a windows terminal program such as HyperTerminal®. A “null-modem” cable is required to enable communications between a PC/laptop and the Gateway. In order to save the configuration, AT&W command must be used. Configuration will be lost after a power cycle if the configuration is not saved Serial Port I/O PIN Null modem I/O PIN configuration DB9 Pin Signal Name Direction Data Carrier Detect Serial Modem Gateway Received Data (by DTE) Serial Modem Gateway Transmitted Data (by DTE) Gateway Serial Modem Data Terminal Ready Gateway Serial Modem Signal Ground Data Set Ready Serial Modem Gateway Request To Send Gateway Serial Modem Clear To Send Serial Modem Gateway + 3.9 V Serial Modem Gateway RST410 Gateway configuration guide...
Manual acknowledgement of duress When using manual acknowledgment, ACK line on gateway relay interface is used to detect and provide acknowledgement back to pendent. Configuration commands Step # Command Description AT^DTRAUTOACK=n When PANIC is received, ACK line 102 is used to detect acknowledgement AT^DTRPANICTIMEOUT=n If this timeout is set, panic Where n is the number of seconds indicating state of the Gateway (0-65535) n=0 disables the timeout will be reset automatically if default value is 60 no communication is detected from the panic state triggering Man Down Pendant.
