locations that require a single module.
• Automatic device mapping
Signature modules transmit information to the loop controller
regarding their circuit locations with respect to other Signature
devices on the wire loop.
• Electronic addressing
Programmable addresses are downloaded from the loop
controller, a PC, or the SIGA-PRO Signature Program/Service
Tool. There are no switches or dials to set.
• Intelligent device with microprocessor
All decisions are made at the module to allow lower
