The DEIF AL8-2 Alarm Panel is a compact, Q96-designed device intended for monitoring and indicating alarm conditions. It features an intuitive push-button programming interface, eliminating the need for jumpers or other complex setup methods. The panel is capable of operating in a master/slave configuration, allowing up to five units to be linked together for expanded monitoring capabilities. A key feature of the AL8-2 is its clear identification of the first alarm received in cases of successive alarms, which is crucial for rapid troubleshooting and response.

Function Description:

The AL8-2 serves as a centralized alarm monitoring unit, capable of registering alarm conditions from up to eight individual input channels. Each input channel can be individually programmed to respond to either an open (N/O) or closed (N/C) signal contact. This flexibility allows the panel to adapt to various sensor types and alarm logic.

A significant aspect of its functionality is the ability to configure output relays. The panel includes two output relays, A and B, which can be activated or deactivated based on alarm conditions. Users can select whether an alarm condition on a specific input channel activates output relay A, output relay B, both, or neither. This enables the AL8-2 to trigger external devices, such as horns, lights, or other control systems, in response to alarms.

The AL8-2 also incorporates an "inhibit" function for incoming alarms. This feature allows specific alarm channels to be temporarily disabled, preventing nuisance alarms during maintenance or specific operational phases. The cancellation of this inhibit function can also be delayed, providing a controlled re-enablement of alarm monitoring.

Cable supervision is another critical function, allowing the panel to detect and indicate a cable failure on an input channel. This ensures the integrity of the alarm signaling path and provides early warning of potential communication issues with sensors. To enable this feature, a 1kΩ resistor must be mounted across the external alarm contact.

Time-delayed registration of alarm conditions is programmable for each input channel. This "delay of alarm" function allows users to set a time delay (from 0 to 40 seconds in 1-second intervals) before an alarm condition is registered. This helps to filter out transient or momentary alarm signals, preventing false alarms and ensuring that only persistent conditions trigger a response.

The activation duration of the output relays can also be configured. For both output relays A and B, users can set a time-limited activation (from 1 to 10 seconds in 1-second intervals) or choose for the activation to be unlimited, continuing until an alarm reset is performed.

In a master/slave configuration, alarms and the horn output can be reset centrally from the master unit. Functional tests, however, are carried out locally on each unit.

Important Technical Specifications:

• Design: Compact Q96
• Programming: Push-button, no jumpers
• Inputs: 8 individual input channels

• Time Limit (Output Relay Activation): 1 to 10 seconds, 1-second intervals (or unlimited)
• Delayed Cancellation of Inhibit Function: 0 to 40 seconds, 1-second intervals
• Cable Supervision: Requires 1kΩ resistor across external alarm contact
• Auxiliary Voltage: 12-48VDC or 110VDC (as indicated on the connection diagram)
• Text Label: For descriptive text of alarm channels and output channels, height 2.7mm recommended for letter-press or typing. Horizontal lines on the label indicate writing area.
• LED Indicators: Green for "POWER ON" (also "DELAY OF ALARM" in programming mode), green/red for programming status and selected functions.
• Operating Temperature: Not explicitly stated, but typically within industrial standards for similar devices.
• Mounting: Panel mount, with bezel and front sheet removable for programming access.

Usage Features:

The AL8-2 is designed for extremely easy operation and programming. The programming process involves three push-buttons: "CHANNEL SELECT," "FUNCTION SELECT," and "ENTER."

1. Programming Mode Entry: Pressing the "PRG" button (a slightly countersunk button requiring a thin, sharp tool) sets the unit into programming status, indicated by a green "PRG" LED. The "DELAY OF ALARM" LED (which also indicates "POWER ON" in normal operation) switches off.
2. Channel Selection: The "CHANNEL SELECT" button cycles through the 8 input channels, with the corresponding LED lighting up green to indicate the selected channel.
3. Function Selection: Once a channel is selected, the "FUNCTION SELECT" button cycles through the individual functions programmable for that channel: N/O or N/C contact, output relay assignment (A, B, both, or neither), inhibit function, cable failure detection, and time delay for alarm registration. LEDs (often in combination of red and green) indicate the current setting for each function.
4. Parameter Adjustment: For functions like time delay, "FUNCTION SELECT" is used to cycle through the available time increments (basic time 0-10 seconds, additional time 0, 10, 20, or 30 seconds).
5. Confirmation: The "ENTER" button confirms the selected function or parameter, saving it to the program memory and moving to the next programmable function in the sequence.
6. Common Functions Programming: To program common functions (output relay A/B activation N/O or N/C, time-limited activation, delayed cancellation of inhibit), the "FUNCTION TEST" button is pressed after entering programming mode. No specific input channel is selected for common functions.
7. Termination of Programming: Pressing "PRG" again exits programming mode and returns the unit to normal operation. The "POWER ON" LED (formerly "DELAY OF ALARM") will light up green.
8. First Alarm Identification: The panel provides clear identification of the first alarm, which is crucial in scenarios with multiple, rapidly occurring alarms.
9. Master/Slave Operation: Up to five AL8-2 units can be interconnected via ribbon cable for expanded monitoring. Alarms and horn resets are centralized on the master unit, simplifying control in larger systems.

Maintenance Features:

• Easy Access for Programming: The bezel and front sheet are designed to be easily removed, providing direct access to the programming front plate. This facilitates quick and straightforward configuration changes.
• Text Label for Identification: A dedicated text label allows users to clearly write or type descriptive text for each alarm channel and output, aiding in system identification and maintenance.
• Marine Applications: For marine use, the front sheet is designed to be glued to prevent unauthorized personnel from altering settings, ensuring system integrity in critical environments.
• Cable Supervision: The cable failure detection feature acts as a proactive maintenance tool, alerting operators to potential wiring issues before they lead to missed alarms.
• Functional Test: The "FUNCTION TEST" push-button allows for local testing of the unit's functionality, aiding in troubleshooting and verification.
• Ribbon Cable Connection: The use of ribbon cables for master/slave configuration simplifies wiring and reduces potential points of failure, although it is critical to disconnect auxiliary supply before connecting/disconnecting ribbon cables.
