This User’s Manual is intended to help for studying operability and maintenance principles of
UO-4S Revision 02 GSM Four-Input Alarm Panel.
Please read the instructions from this manual completely before connecting, adjusting, oper-
ating, or maintaining this device
The following terms are used throughout the Manual:
Alarm Loop: The electrical circuit with non-addressable fire or intrusion detectors (or other non-
addressable devices) included. Actuation of a single detector brought in an alarm loop
causes activation of the loop as a whole, so the actuated detector can be located only with
the accuracy of an alarm loop.
Zone:
A minimum part of the security and safety installation that can be monitored and controlled
independently. Depending on the context, the term “zone” in an Orion ISS can be understood
as an alarm loop, an addressable detector, a monitored circuit of an input module etc.
Partition: A number of zones that can be controlled by user as a whole. As a rule, zones are
combined into partitions depending on their locations (e.g., one partition can involve all
zones in a single premise)
Arm/Disarm: This action means activation or termination of monitoring of defense zones and
triggering alarms
Integration Time: A time interval during which alterations of loop resistance are not considered as
loop’s being activated and the alarm loop doesn’t proceed to an alarm status
Network Address (Address): A unique number of the device (from 1 to 127) within a local RS-485
