3.1.2.1 Auxiliary Alarms Inputs
The T803-02 has 4 closure alarm inputs. On every falling edge the associated alarm is
(re)triggered, and sent when the T803 becomes idle. Alarm0 has higher priority than
Alarm3, in that the alarm will be actioned first.
Maximum input voltage = 5V
Note: The behaviour is different from the T803-00 as it will resend any user pro-
grammed tone sequence if re-triggered when already latched.
3.1.2.2 Auxiliary Control Outputs
The 4 Auxiliary outputs are of common collector type (they will only sink current), and
are rated to a maximum of 50V and 250mA. The outputs can be controlled via a function
tone sequence (Enable, Toggle, or Disable) or enabled on an alarm or confirmation.
3.1.3 Line Interface
The following table describes the pin configuration for interfacing with the T803 on
4-wire and 2-wire networks.
The T803 accommodates an input signal range of 28dB. Normally this is sufficient, how-
ever by shorting JP200 (found on the T803 PCB) an extra 15dB gain is added.
