SIGA-IOSIGA-IO and MIO Input/Output Modules are intelligent analogaddressable devices that form part of EST’s Signature line ofproducts. The actual operation of the SIGA-IO and MIO is determinedby the “personality code” selected by the installer,whichisdownloaded to the module fromthe Signatureloop controllerduringsystem configuration.

Standard Features

EST Catalog u Intelligent Input-Output

• 10 modules in one

Multiple applications including normally-open or normallyclosed

alarm relay

and latching or non-latching alarm inputs.


installer selects one of up to 10 personality codes to be



the loop controller.

• Adjustable time delays

User sets the expected response time (5 - 120 seconds) for

maximum flexibility.

• Plug in (UIO) or standard 1-gang mount

UIO versions allow quick installation where multiple modules

are required. The 1-gang mount version is ideal for remote

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 con-

troller, 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 communication

speed with substantially improved




time and less sensitivity to line noise and loop wiring 

properties; twisted or shielded wire is not required.
