Alarm Cards Introduction

Chapter 1
Alarm Cards

1.1 Introduction

This chapter provides installation, configuration, and troubleshooting information for the
Alarm cards. These cards are labeled as the ALR 4+4, ALR 4+3PF, and ALR 28+14 Cards on
their faceplate ejectors.

The Alarm cards allow the system to report alarms to external alarm annunciators and other
systems. Each card also receives alarms report ed by external devices. Each car d has switches
for outbound alarms, and sensors that detect incoming alarms from the external equipment.

Only one Alarm card can reside in the Integrated Access System at a time. These cards are
discussed below.

Each card has two alarm notificat ion modes. The "Switch/Act On" (outbound) function allows
you to report inte rnal system alarms to external dev ices, such as buzze rs, bells, and li ghts. The
"Sensor/T rig On" (inbound) f unction allows you to r eceive externa l alarms through sensors on
the card.

1.2 Alarm Card Descriptions

1.2.1 ALR 4+4 Card Description (840160)

The ALR 4+4 Card has four outbound alarm switches and four inbound alarm sensors. The
outbound switches report internal alarms to external devices by triggering form-C relay
contact closures (120 VA C, 0.5A). The in bound sens ors report exte rn al alar ms to the sys tem.
All external alarms reported by sensors are listed in the alarm history file.

An Integrated Access S yst em wit h a n ALR 4 +4 Ca rd can respond to four external alarms for
control of environmental and security conditions, and also provide four internal alarms to
outside alarm indicators. For example, a critical alarm can illuminate a red light at the office.

Each inbound alarm sensor has the capability of responding to one external condition. The
alarms appear on the screen in the al arm sect ion, showi ng th e alarm as a SENSOR alarm and
includes the slot number and sensor number of the condition (e.g., SENSOR U7-4).

The inbound alarm sensors can use either 12V or 48V. Both JP1 and JP2 jumpers should be
set for the proper voltage. The inbound sensors are isolated from ground.

Each outbound "floating" relay has normally open contacts and normally closed contacts. It
responds to major , crit ical, minor, and informational alarms, and acti vates an ex ternal de vice.
Two relays are provided for each Alarm Card port. The relays are dual-pole, doub le-throw.

1.2.1.1 Card Jumpers/Switch Settings

The US/Euro jumper pair on t he ALR 4+4 car d must be con figured to t he same set ting as that

1.2.2 ALR 4+3PF Card Description (840260)

The ALR 4+3PF Card has four outbound switches and three inbound sensors. This card is
similar to the ALR 4+4 Card, except that its fourth alarm port can on ly be used as an outbound
alarm to show the system power unit has failed. The ALR 4+3PF Card is especia lly helpful in
locations where a loss of power to any system units is a critical problem. See Figure 1-2.

A -48 VDC power source is optional with this card. It may be provided by either an
AC-to-DC Converter or an external source.

1.2.3.1 Card Jumpers/Switch Settings

The ALR 28+14 Card has numerous jumper and other settings, as shown in Figure 1-3. The
sensors allow you to connect up to 28 external devices to the card. These sensors may be
powered either externally or from the alarm card. They are divided into two groups, with 14
sensors per group. Each sen sor group is routed through one of two Amphenol jacks, and you
can control the volt age to eac h group by oper ating a vol tage cont rol switc h on the alar m card.
Detailed instructions for sensor control are provided later in this chapter.

The switches allow the ca rd to control up to 14 external devices. As with the sensors, the
switches are divided between the two Amphenol connectors into two groups of seven switches
each. Twelve of the switches are Form C (o pen or c losed bas ed on us er inp ut), on e is Fo rm A
(always open), and one is Form B (always cl osed ). One of the swit che s can also be se t to trip
if a system power failure o ccurs. Instructions for switch control are provided later in this
chapter.

The alarm information can also be transmitted to a central site via SNM P or other user- defined
parameters.

Audible Alarm Buzzer Volume Setting

The ALR 28+14 Card has an on-board buzzer for audible alarms. You can set the buzzer to
activate when a particular sensor detects an incoming alarm. The buzzer volume is set by a
control dial marked VOL, which you can adjust with a small screwdriver.

U.S./European Voltage Jumpers

You can configure the ALR 28+14 Ca rd fo r e ither U.S. or Europea n opera tion b y moving the
jumpers located on JP64. One jumper is pro vided for ea ch alarm sens or on the car d. Inserting
a jumper on the left-si de two pins s elects U.S. v oltages. I nsertin g the ju mper on the r ight-si de
two pins selects European voltages. All jumpers should be set to the same position, and this
setting should match t he configuration of th e system chassis for th e card to work properly . The
factory default jumper setting is US.

Voltage Control Switches

Use switches S1 and S 2 to contr ol the vo ltage su pplied to each g roup of ac tive sen sors. When
either switch is set to SYS, the board supplies +12 and -12 VDC power to the sensor group
associated with that Amphenol con nector. When a switch is set to BAT , the ALR 28+14 Card
supplies external telco power to the sensors in that group.

You can set the switches individually (i.e., one can be set to SYS and the other to BAT).
However, this will affect all 14 sensors in the respective group.

Alarm Cards 1-15

Switch S1 controls the sensor s on the J3 (lower) connec tor , and switch S2 controls the sensors
on the J4 (upper) connector.

The factory default setting for the voltage control switches is SYS.

Alarm Sensor Jumpers

Each sensor is associated with a pair of jumpers that control whether the sensor is powered
from the card (active mod e) or an exter nal device (pa ssive mode). The passive mode p rovides
2500V of isolation. Figure 1-4 shows these options.

The jumpers are separated into two grou ps of 14 jumper pairs . The upper group is associa ted
with the sensors on the upper amphenol connec tor (J4), and the lo wer group is associ ated with
the sensors on the lower amphenol connector (J3). The jumper pair sensor assignments are
silk-screened on the card. The jumpers for sensor 1 are indicated as SI1, and the jumpers for
sensor 28 are indicated as SI28. One of these sensor groups is detailed in Figure 1-5.

The jumper pairs t hat correspond to each sensor are numbere d accordingly. For e xampl e, the
jumper pairs for se nsor 1 2 are in row SI 12 of t he lo wer ju mper group (columns JP1 a nd JP 2).
Similarly, the jumper pairs that correspond to sensor 25 are in row SI25 of the upper jumper
group (columns JP3 and JP4).

Power Failure Notification

If a system power failur e occurs, switch 1 can act as a fail- safe switch to ac tivate a device tha t
notifies an operator. For this to occur , you must inst all a j umper on jumpe r pair JP63 near t he
center of the card. The contact for switch 1 will close if the system loses power, establishing
a circuit that can be used to power an external warning device. The current source must be
provided by the external device.

1.2.3.2 Installing the Alarm Card

The Alarm card can be installed in any user card slot. These slots are U1 to U8 on the
two-sided chassis and front-loading chassis with power supplies on top, and P1 to P4 or W1
to W4 on the front-loading chassis with power supplies on the side.

1.3.1 Alarm Filter Screen Sensor Setting

First, make sure the master setting for all alarm senso rs is set properly as the SENSOR vari able
in the Alarm Filter Screen. To set this variable, first select Alarms from the System Main
Screen, then choose Filters. This will display a list of alarm filters, as shown in Figure 1-8.

In this menu, use the arrow keys to highlight the first column of the SENSOR line. Pressing
<Enter> displays the optio ns ignore, log, and report. The option chosen here will act as the
highest-level option for all alarm card sensors. If this variable is set to ignore, any alarm

conditions on the alarm card will be ignored, even if you set them up individually to log or
report.

Likewise, if you set this variable to log, all sensors on the Alarm card that are set to anything
other than ignore will be logged but not reported. For this reason, it is crucial that the
SENSOR variable be set to report (see Figure 1-8).

ST ATE

The State setting determines whether the port is active or inactive. An inactive port does not
occupy a time slot on a WAN link. Set the State setting to stdby (standby) for ports you are
not using or have not yet configur ed. Set it to actv (active) for ports that are ready for use. The
default value is stdby.

WAN/SRV

The WAN setting identifies the WAN link assigned to this port. The default value is none.

TS

The TS setting identifi es the ti me slot on the WAN link to which this por t is assi gned. Values
range from 1 to 24 for T1 links and 1 to 31 for E1 links. Time slot 16 is not available on E1
links that are programmed for cas or ccs signaling. For a display of the available time slots,
refer to your cross-connect map for the WAN link. The default value is n/a. See Chapter 4,
System Configuration and Operation for more information regarding cross-connect maps.

MODE

The Mode setting shoul d be determined by t he type of equipment to which you are con necting
the port. All options use two-wi re balanced connection s. The fxs (Foreign Exchange - Stati on)
option allows you to connect a telephone to the system.

The plar (private line automatic ringdown) option provides point-to-point unswitched
connections between two telephone sets. This configuration is usually not attached to an
exchange or switch; rather, it provides a “hot li ne” between two locations.

Before activating thi s port, verify the behavior expected by both the stat ion and remote central
office equipment, and make sure the system is properly configured.

Rx TL

The Receive Transmission Level Point setting controls the amount of gain or attenuation
added to signals after the y are decod ed to analog signals. To increa se t he si gna l level, set the
RX TLP setting to a positive number (i.e., the l arger the number, the more gain is adde d) . To
decrease the signal leve l, set the RX TLP setting to a negative number (i .e., the more negative
the number, the more the signal level is decreased). For example, an incoming signal at -5
dBm can be increased to -3 dBm by setting RX TLP to +2 dB. Accept able val ues range fr om

-10.0 dB to +2.0 dB. The default value is -5.0.

Tx TLP

The Transmit Transmission Level Point setting controls the amount of gain or attenuation
added to signals after they are received from the local anal og port and before t hey are encoded
to digital PCM signals. To increase the signal level, set the TX TLP setting to a negative
number (i.e., the more negative the number, the more gain is added). To decrease the signal
level, set the TX TLP settin g to a positive number (i. e., the more positive the number, the more
the signal level i s decr eased) . For ex ample , an in coming s ign al at -5 dBm can be inc rease d to

-2 dBm by setting TX TLP to -3 dB. Acceptable va lues ra nge fro m -10.0 dB to +5.0 dB . The
default value is +2.0.

CODING

The Coding setting sets the PCM companding method used for a port. In general, in the
T1/North American enviro nment use µ-law coding. In the E1/International envi ronment , us e
a-inv (inverted A-law) or a-law coding; a-inv provides greater 1s density than a-law. The
coding default is dete rmined by the type of c ard in the WAN port you selec t. The default val ue
is u-law (Note: On th e syst em screens, "u" is u sed in place of " µ" becau se of ASCII c haracter
limitation s, but should be read as "mu-law.").

RINGBK

The ringback setting specifies whether a ringback tone is generated by the system and sent
towards the network. This option should be turned on when the network does not provide an
audible ringing tone to the calling party. The default value is off.

1.5 Alarm Card Troubleshooting

Alarm card problems could indicate a number of possible causes. Typically, a problem is
indicated by the loss of an incoming alarm signal on a sensor port or the lack of a contact
closure/open in response to an internal alarm. Steps designed to isolate the source of the
problem and return the card to normal operation are detailed below. When troubleshooting
Alarm card problems, you should follow this general sequence:

1. Verify that the US/EUR jumper i s corr ectly posit ioned on the Alar m card t o match t he
US/EUR jumper on the chassi s. Also ve rify th at the volt age le vel s ele cted is th e sam e on
JP1 and JP2.

2. Verify that the Alarm card sensor filter (SENSOR) is set to either log or report in the
Alarm Filters Menu. This men u is acces sed by s elect ing " Alarms" from the Main Screen
(not the Alarm Card Screen), and t hen selecting "Filters." Column 1 lists the filter setting
(ignore, log, or r eport). Y ou can change the fil ter setting by highl ighting the item you wis h
to change and pressing the <Enter> key. Use the arrow keys to highlight a new filter
setting and press the <Enter> key again. If you are satisfie d with your selections,
remember to "Save" before exi ting the screen. If you make any change s and then attempt
to exit the screen without saving, you will be prompted "Ok to lose changes (y/n)?" You
must select "y" or "n". If you select "y", any changes will be lost and all selections will
revert to the last saved st ate.

3. On the Alarm card menu, verify that the switch/ sensor in question is set to active ( actv).
If set correctly and the pr oblem is with a switch (contact), go to step 4. If the problem is
with a sensor, go to step 6.

4. Verify that the amphenol cable is connected correctly to the Alarm card. At a
cross-connection point between the Alarm card and the external “scan point”, open the
circuit under test. Connect a Volt -Ohmmeter se t to read res ista nce acros s the Alarm card
contact in question. If no alarm of the type (Major, Minor or Any) that the contact is
programmed to act upon is pre sent, and it i s a normally open (NO) contact, the met er will
read infinite resis tan ce. I f you are tes ti ng a nor mall y cl ose d (NC) cont act , th e meter will
read 0 ohms resistance.

5. Generate an alarm of the type (Major, Minor or Any) that the contact is programmed
to act upon. The Volt-Ohmm eter should detect a resistance change from 0 to infinite or
infinite to 0, depending on the type of contact (NO or NC). If no change is detected, the
switch port may be defective.

6. Verify the amphenol cable is connected correctly to the Alarm card. At a
cross-connection point between the Alarm card and the external equipment, open the
circuit under test. Connect a short across the Alarm card sensor input in question. A
SENSOR alarm should be reported. If no alarm is reported, the sensor port may be
defective.

7. If the Alarm card is determined to be faulty, replace it and return the faulty unit for
repair to the location specified by your distributor.
