FOCUS 200 PLUS Installation and Setup Guide

Gateway Off-Normal Conditions

During operation, the gateway polls the point sensors that are connected to its trunk and stores the
status of the protection loop. When interrogated, the gateway reports any change in status to the
control unit where it is processed to determine whether there is an alarm or trouble condition. Specific
off-normal conditions monitored by the gateway and reported to the control unit are as follows:
PID Gateway
Off-Normal Condition
Cross
Open
Comm Fail
Point Tamper
Multiple Conditions
PIDs addressed the same
SIM Gateway
Off-Normal Condition
Cross
Open
Comm Fail
Point Tamper
Multiple Conditions
Diagnostics
RF Gateway
Off-Normal Condition
Cross
Open
Comm Fail
Point Tamper
5-28
Cause
A short across the EOLR of the protection loop.
An open or ground in the protection loop and may include the sensor
tamper.
Failure to receive a response from a point when it is interrogated. PID
may be defective, or there may be a fault with the cable to the gateway
trunk, or PID has not been addressed correctly.
Activation of a tamper on a PID.
These are combinations of cross and open, cross and tamper, open and
tamper, and cross, open, and tamper.
The gateway will interpret this as a tamper plus comm fail.
Cause
Indicates an alarm condition.
Indicates a trouble condition.
Failure to receive a response from a point when it is interrogated. SIM
may be defective, or there may be a fault with the cable to the gateway,
or the gateway has been addressed incorrectly.
Activation of a tamper on a sensor. If the BA group is Nite Set, this is
interpreted as an alarm.
These are combinations of cross and open (alarm and trouble), cross and
tamper (alarm and tamper), open, and tamper (trouble and tamper), and
cross, open, and tamper (alarm, trouble and tamper).
The false alarm immunity of the sensors is impaired. Examples: A Dual
motion detector with one of its technologies malfunctioning may increase
in sensitivity to motion. A smoke detector that is dirty may increase in
sensitivity to smoke.
Cause
FA point: Alarm condition.
BA point: Normal condition.
FA point: Trouble condition.
BA point: Alarm condition.
1. Failure to receive a response from a point when it is interrogated.
RF transmitter may be defective, or there may be a fault with the cable
to the gateway trunk, or the gateway has not been addressed correctly.
2. Low battery condition in an RF transmitter.
Note: To determine which of these conditions the system is
annunciating, check the system's history log.
