Alarm Cards
10.1 Introduction
This chapter provides installation, configuration, and troubleshooting information for the
Alarm card. The card is labeled as the ALR 4+4 on the faceplate ejector.
The Alarm card allow the system to report alarms to external alarm annunciators and other
systems. Each card also receives alarms reported by external devices. 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 notification modes. The "Switch/Act On" (outbound) function allows
you to report internal system alarms to external devices, such as buzzers, bells, and lights. The
"Sensor/Trig On" (inbound) function allows you to receive external alarms through sensors on
the card.
10.2 Alarm Card Descriptions
10.2.1 ALR 4+4 Card Description (8000-ALARM-4P)
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 external alarms to the system.
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 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 alarm section, showing the 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.
