Intelligent I/O Relay Output & Switch Monitor

The Advanced Intelligent I/O Relay Output & Switch

Monitor (55000-820ADV) is an application specifi c
addressable module for use with the AxisAX Series
Intelligent Fire Alarm Control Panels. Each module is SLC
loop powered, eliminating the need for additional fi eld
wiring and external power supplies.

Designed for installation on Advanced AxisAX Series
SLC (signaling line circuit), the 55000-820ADV
provides a single initiating device circuit (IDC) input,
an independently controlled Form-C relay contact
output, and an unmonitored optically isolated voltage
input. The 55000-820ADV utilizes the Advanced unique
sub-addressing for both the independently controlled
relay and the optically isolated voltage input. By sub addressing
these I/O features, AxisAX Series system point
capacities are expanded with installation, programming,
and commissioning time minimized. The 55000-820ADV
mounts to the front of a standard 4” square or 2-gang
electrical outlet box.
