Introduction
The Prosense comprises a gas detector body and a choice of sensors heads for detecting
flammable gas, toxic gas and oxygen. The construction of Prosense allows it to be used in
non-hazardous safe area locations.
Prosense detectors can be configured with a wide range of different sensors may be used to
detect a broader range of target gases. The detector provides three programmable relays
which are FAULT, ALARM1 and ALARM2 for controlling external equipment e.g. alarms,
sirens, valves or switches. The detector can be configured to communicate RS485 modbus
protocal with an optional module and also provides FAULT and ALARM1 relay outputs at
same time.
