RST410 Gateway conguration guide
Overview
This document is designed to explain the conguration 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 congure the gateway to provide acknowledgment to Pendent only
upon external input. This document explains the commands and wiring to use the
manual acknowledgment method.

Conguration
The Gateway supports AT style commands (AT^) for conguration. 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 conguration, AT&W
command must be used. Conguration will be lost after a power cycle if the
conguration is not saved

Manual acknowledgement of duress
When using manual acknowledgment, ACK line on gateway relay interface is used
to detect and provide acknowledgement back to pendent.
Conguration commands
Step # Command Description
1 AT^DTRAUTOACK=n When PANIC is received, ACK
line 102 is used to detect
acknowledgement
2 AT^DTRPANICTIMEOUT=n
Where n is the number of seconds
(0-65535) n=0 disables the timeout
default value is 60
If this timeout is set, panic
indicating state of the Gateway
will be reset automatically if
no communication is detected
from the panic state triggering

ACK line handling
ACK line must be supplied with +3V in normal operation. In order to acknowledge
the PANIC, the ACK input needs to be pulled negative to below -3V.
