FOCUS 200 PLUS Installation and Setup Guide5-28Gateway Off-Normal ConditionsDuring operation, the gateway polls the point sensors that are connected to its trunk and stores thestatus of the protection loop. When interrogated, the gateway reports any change in status to thecontrol unit where it is processed to determine whether there is an alarm or trouble condition. Specificoff-normal conditions monitored by the gateway and reported to the control unit are as follows:PID GatewayOff-Normal Condition CauseCross A short across the EOLR of the protection loop.Open An open or ground in the protection loop and may include the sensortamper.Comm Fail Failure to receive a response from a point when it is interrogated. PIDmay be defective, or there may be a fault with the cable to the gatewaytrunk, or PID has not been addressed correctly.Point Tamper Activation of a tamper on a PID.Multiple Conditions These are combinations of cross and open, cross and tamper, open andtamper, and cross, open, and tamper.PIDs addressed the same The gateway will interpret this as a tamper plus comm fail.SIM GatewayOff-Normal Condition CauseCross Indicates an alarm condition.Open Indicates a trouble condition.Comm Fail Failure to receive a response from a point when it is interrogated. SIMmay be defective, or there may be a fault with the cable to the gateway,or the gateway has been addressed incorrectly.Point Tamper Activation of a tamper on a sensor. If the BA group is Nite Set, this isinterpreted as an alarm.Multiple Conditions These are combinations of cross and open (alarm and trouble), cross andtamper (alarm and tamper), open, and tamper (trouble and tamper), andcross, open, and tamper (alarm, trouble and tamper).Diagnostics The false alarm immunity of the sensors is impaired. Examples: A Dualmotion detector with one of its technologies malfunctioning may increasein sensitivity to motion. A smoke detector that is dirty may increase insensitivity to smoke.RF GatewayOff-Normal Condition CauseCross FA point: Alarm condition.BA point: Normal condition.Open FA point: Trouble condition.BA point: Alarm condition.Comm Fail 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 cableto 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 isannunciating, check the system's history log.Point Tamper Activation of a tamper on an RF transmitter.
