JA37-300
Aural Message Generator - 3 Channel - Analog Inputs
SECTION 1 - DESCRIPTION
1.1
System Overview
The JA37-300 Aural Message Generator - 3 Channel - Analog Inputs is a dual channel alerting system that provides
up to three different messages.
The JA37-300 is setup on a per installation basis using a Configuration Cable and downloading the system
configuration settings and aural messages into non-volatile devices.
1.2
Features Overview
The JA37-300 unit features an industry standard D-Sub connector pin-out to allow easy field upgrades.
All internal adjustments are configured using the proprietary ProCS (Product Configuration Software).
A port is provided beside the main connector for connection to the configuration cable.
All audio outputs are balanced.
The message generator input types may be configured as one of the following: discrete trigger, tachometer, 5Vdc
transducer, 100 mVdc transducer, K-Type thermocouple.
Each analog input may be configured to trigger when the input signal is 'greater than' or 'less than' the configured
level.
Two isolation amplifiers are provided for mixing in other audio signals.
