Squelch Polarity radio busy indicated by high or low signal Radio Warmup Time in msec Announcements over Telephone The most common way of reporting alarms is over the telephone The SPX may be configured to use tone or pulse dialling It will either monitor for call progress tones or simply announce the voice message after dialling The voice message consists of the Site ID Group ID the list of alarms present and the phrase Enter Acknowledge Code The entire message is repeated three times with a pause of five seconds after each to wait for an Acknowledge Code Overview 2 6 A series of telephone numbers may be programmed into the directory If an acknowledgement is not received after calling the first number the SPX will continue to dial through the directory until it reaches a number where it is acknowledged If an acknowledgement is not received by the time it reaches the end of the directory it will continue dialling from the top Instructions for announcing alarms over the telephone will generally be of the following format 1 DIAL 2559544 VOICE 2 DIAL 2592343 VOICE 3 DIAL 2385832 VOICE where DIAL is the dial command the digits represent the telephone number and VOICE is the command to announce the alarm Note that all DTMF digits are valid as part of a DIAL command including A B C D and the asterisk and octothorpe The exclamation mark has a special meaning Each in a telephone

When an alarm occurs the SPX announces the name of the point followed by the word High or Low The numerical value of the analog complete with decimal places and units is announced when you interrogate the SPX Note that it may take from 5 to 10 seconds to poll all 110 points so values are not necessarily in real time You must specify the maximum and minimum decimal and binary values high and low setpoints plus the engineering units in which analog values arereported You must also specify hysteresis so that the unit can calculate when an analog alarm is reset Overview 2 3 Totalizers are a subset of analogs These points never alarm as they do not have setpoints However the accumulated total will be announced whenever the unit is interrogated A Comms Watch point is used when more than one PLC is monitored The point specifies the maximum number of consecutive communications failures which may occur with that address before an alarm is announced In addition to a voice identifier each alarm point should be programmed with a 16 character alpha numeric name This name will be displayed when scrolling through alarms on the front panel of the SPX when programming the voice message or when alarms are printed Points may be completely configured but temporarily disabled When defining your alarms be sure to address all of the following items on the Point screen for Digital Analog Totalizer Comms Watch and External Ala

12. Overview 2 10 terminal The SPX automatically inserts the paging code and the password if required then sends the individual pager code as specified in the directory in this case 97531 The alpha numeric message consists of the Site ID Group ID and Alarm ID associated with the alarming point and indicates the presence of any additional alarms The following parameter must be specified in the General Configuration screen in order to send alpha numeric pages TAP Paging Paging terminal type and password 5 How do you want to respond to an alarm Next you must decide how you want the called party to respond to the alarm In most cases it is desirable that the alarm be acknowledged Therefore in its default state the SPX prompts the called party to Enter Acknowledge Code after the alarms have been announced The SPX waits five seconds to receive the code then proceeds to its next message repetition or directory instruction The SPX is normally acknowledged by sending the Acknowledge Code a one to seven digit DTMF code over the radio or telephone The SPX may also be acknowledged by pressing the ACK button on the front of the unit or the remote ACK switch if one has been installed If you enter the Acknowledge Code followed by an octothorpe the SPX acknowledges the alarms for a programmed period of time When the time expires the SPX checks the points again and if the same alarms are present it reinitiates the reporting
13. PLC 5 Use the Program screen to program the site voice identifier after the configuration has been programmed 2 What constitutes an alarm The next step in configuring the SPX is to define what constitutes an alarm Alarm points may be of several types Internal Digital Analog Totalizer Comms Watch or External A digital point has two states normal and alarm The SPX looks for a zero or a one in the PLC register associated with that point The voice message for a digital point is normally programmed to announce the alarm condition when it is activated e g Intrusion Alarm An alarm may be configured as momentary or latched A momentary alarm changes state and stays that way until the condition returns to normal Fora latched point a pulse registers as an alarm Once acknowledged it is considered to have returned to normal The next occurrence of the pulse is a new alarm Note that the first two alarm points in the SPX are dedicated one to a power failure and the other to a communications failure with the PLC Power fail contacts are wired into the DB15 Power Radio connector the only hardware alarm on the ProTalk SPX Additional Comms Watch points may be configured if more than one PLC is being polled For an analog point the SPX reads an actual value from the register in the PLC The SPX recognizes an alarm when a high or low setpoint is exceeded Hysteresis allows you to specify when the alarm is considered to have reset
