IMACS Alarm Card

Overview

The Alarm card slots into one of the User card slots and allows 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. Each card has two alarm notification modes. The “Switch/Act On” (outbound) function allows the user 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.

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 IMACS alarm history file.

An IMACS System equipped 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.

Each outbound “floating” relay has normally open contacts and normally closed contacts. It responds to major, critical, minor, and informational alarms, and activates an external device. Two relays are provided for each Alarm Card port. The relays are dual-pole, double-throw.
