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 (8401), ALR 4+3PF (8402), and ALR
28+14 (8403) 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 devi ces. Each card 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) func tion allows
you to report inte rnal system alar ms to external devices, such as bu zzers, bells, and lights. The
"Sensor/T rig On" (inbound ) function allows you to receive externa l alarms through sens ors on
the card.
1.2 Alarm Card Descriptions
1.2.1 ALR 4+4 Card Description (8401)
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 VAC, 0.5A). The inbound sensors report extern al alar ms to the sys tem.
All external alarms reported by sensors are listed in the alarm history file.
An integrated access system with an ALR 4+4 Card can respond to four external alarms for
control of environmental and securi t y condit i ons, 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 the al arm as a SENSOR ala rm and
includes the slot number and sensor number of the condition (e.g., SENSOR U7-4).
The inbound alarm sensors can be optioned to utilize 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 inf ormational alarms, and a ctivates an ex terna l device.
T wo relays are provided for e ach Alarm Card port. The relays are dual-pole, double-thro w. See
Figure 1-1.

1.2.2 ALR 4+3PF Card Description (8402)
The ALR 4+3PF Card has four outbound switches and three inbound sensors. This card is
similar to the ALR 4+4 Card, except tha t its fourth alarm port can only be used as an
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.

1.2.3 ALR 28+14 Card Description (8403)
The ALR 28+14 Card has 28 sensors for incoming external alarms. Each sensor controls its
own alarm. The card also uses 14 switches to control external devices, and provides a single
FXS voice port.
The sensors allow you to connec t up t o 28 e xterna l devi ces t o the card. The se sen sors ma y be
powered either externally or from the alarm card. They are divided into two groups, with 14
sensors per group. Each sensor group is routed thr oug h one of t w o Amphenol jacks, and you
can control the voltag e to each gr oup by operat ing a volta ge control switch on the al arm card.
Detailed i nstructions for sensor contr ol are provided later in this chapter.
The switches allow the card 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 swi tches
each. Twelve of the switch es are Form C (open or clo sed bas ed on us er inp ut), on e i s Form A
(always open), and one is Form B (always closed). One of th e swit ches can also be set to tr ip
if a system power failure occurs. Instructions for switch control are provided later in this
chapter.
The alarm informatio n can also be transmit ted to a central site via SNMP or other user-defined
parameters.
1.2.3.1 Card Jumpers/Switch Settings
The ALR 28+14 Card has numerous jumper an d other settings, as shown in Figure 1- 3. These
settings are discussed in the following paragraphs.

U.S./European Voltage Jumpers
You can co nfigur e the ALR 28+14 Ca rd for e ither U.S. or Europea n opera tion b y moving the
jumpers located on JP64. One jumpe r is provid ed for each al arm sensor on the card. Ins erting
a jumper on the left-si de two pi ns select s U.S. volt ages. Inse rting th e jump er 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 t he system chassis for the card to work properl y . The
factory default jumper setting is US.
Voltage Control Switches
Use switches S1 and S2 t o control the volt age suppl ied to ea ch group of active sensors. W hen
either switch is set to SYS, the board supplies +12 and -12 VDC power to the sensor group
associated with th at Amphen ol connec tor. Whe n a swi tch i s set to BAT, t he AL R 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.
Switch S1 controls the sensor s on the J3 (lower) connec tor, and swi tch S2 controls the se nsors
on the J4 (upper) connector.
The factory default setting for the voltage control switches is
SYS

jumper pairs for se nsor 1 2 are in ro w SI12 o f the lower ju mper gr oup (co lumns J P1 a nd JP2) .
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, swit ch 1 can act as a fai l-safe switch to activate a de vice that
notifies an operator. For th is to occ ur, you must install 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.

plar
connections between two telephone sets. This configuration is usually not attached to an
exchange or switch; rather, it provides a “hot line” between two locations.

Rx TL
The Receive Transmission Level Point setting controls the amount of gain or attenuation
added to signals after they are decoded to analog signals. To increase the signal level, set the
RX TLP setting to a positive nu mb er (i. e., t he 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

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

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. Veri fy tha t 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 chassis. Also ve rify that th e voltage level selected is the same on
JP1 and JP2.
2. Verify that the Alarm card sensor filter (SENSOR) is set to either
Alarm Filters Menu. This men u is ac cessed by select ing "Alarms" from the Main Screen
(not the Alarm Card Screen) , and then selecti ng "Filters." Column 1 lists the filter setting
(ignore, log, or report). You can change the filter setting by highlighting the item you
wish to change and pressin g the <Enter> key. Use the arrow keys to highlight a new filter
setting and press the <Enter> key again. If you are satisfied with your selections,
remember to "Save" before exiting the screen. If you make any changes and then attempt
to exit the screen wit hout sa ving, you will be prompted "Ok to l ose chan ges (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 state.
3. On the Alarm card menu, verify that the switch/senso r in question is s et to active (

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. Conne ct a Volt-Ohmmeter set to read resist ance acros s the Alarm card

5. Generate an alarm of the type (Major, Minor or Any) that the contact is programmed
to act upon. The Volt-Ohmmeter should detect a resistance change from 0 to infinite or
infinite to 0, dependi ng on the type of contact ( NO or NC) . If no c hang e i s det ec te d, t he

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.
If the Alarm card is determined to be faulty, replace it and return the faulty unit for
