2000 Series Addressable I/O Module

2000 series IO units operate on the fire panel loops to monitor input contacts and independently switch relay outputs for control of external equipment. Each I/O module occupies only one address on the addressable loop regardless of the number of inputs or outputs on that module.

All 2000 series devices utilize an advanced digital data communications protocol with extensive error correction algorithms to ensure system reliability. Up to 128 devices may be installed on every communication loop. Device addressing is via two convenient, easy to use, rotary switches
