Conventional Fire Alarm-Suppression Control Unit. A Single Hazard Agent Releasing Unit which provides configuration flexibility in a compact footprint to protect life and assets in commercial, high-tech and industrial applications. The AEGIS 2.0 control unit has a NEMA1 enclosure and an option for door mounted Manual Release and Abort switches to avoid the additional expense of wall mounting these items. The AEGIS 2.0 is well equipped to handle all special hazard extinguishing systems due to the high degree of programming flexibility provided and the following full complement of input and output circuits: • Three (3) Class A or Class B Detection Circuits • Two (2) Class A or Class B Supervisory Circuits • Option to Use SUP 1 as Fourth Detection Circuit • One (1) Class A or Class B Manual Release Circuit • One (1) Class A or Class B Abort Input Circuit • Three (3) Class A or Class B Notification Appliance Circuits • Two (2) Class B Agent Release Circuits • Three (3) Programmable and 1 Trouble Form-C Relays DETECTION CIRCUITS The Detection Circuits support Conventional 700 Series, CPD-705x Ionization Smoke, PSD-715x Photoelectric Smoke and THD-705x Heat Detectors as well as Normally Open contact closure type devices. Two circuits are dedicated to the main suppression function and can be programmed to activate the release circuits by either single-shot or cross-zone input. The user configuration allows automatic release via detection to be delayed from 0 to 60 seconds in 10-second intervals and also allows a choice of which of the two Agent Release Circuits to activate. The third Detection Circuit is programmable for either Waterflow or as an independent Detection circuit. When programmed for Waterflow, Notification Appliance Circuits can be programmed as Non-Silenceable as required by certain jurisdictions. Additionally, the Supervisory 1 circuit can be configured to be the fourth detection circuit. SUPERVISORY CIRCUITS The Supervisory Circuits accept Normally Open contact closure type devices such as pressure switches on the agent cylinders or on the water or air pipe network. The system configuration enables the supervisory input to be a participant in the suppression function. For example, low air supervisory can be included with detection for release of pre-action systems as required by certain jurisdictions. MANUAL RELEASE AND ABORT CIRCUITS Both the Manual Release and Abort Circuits accept Normally Open contact closure type devices. Activation of the Agent Release Circuits can either be instantaneous or delayed up to 30 seconds (maximum) upon receipt of Manual Release input. Agent release can be temporarily delayed by activating the Abort Circuit. The Abort input can be programmed for 6 modes of operation. These include the UL 10-second mode, the full-delay mode, the IRI mode, two NYC modes, or the abort can be disabled. Aborts can also be programmed to be applicable for either one (ARC 1) or both Agent Release Circuits thereby allowing use with Deluge/PreAction systems. NOTIFICATION APPLIANCE CIRCUITS (NAC) The three Notification Appliance Circuits are rated 1.5 Amps each and accept polarized 24 VDC Notification Appliances. Each circuit is driven independently and is user configurable for First Alarm, Pre-Release, and Releasing as well as for 60 BPM, 120 BPM, Temporal, or Continuous pattern. The control unit supports appliances that provide the option to use silenceable horns and non-silenceable strobes on the same NAC. Multiple NAC circuits (connected to audible devices only) programmed with the same master code pattern are synchronized, regardless of any differing starting times that preceded their concurrent operation. The NACs configuration includes a user-selectable intelligent synchronization feature which allows a silenceable horn to be shut off while the strobe continues to flash in synchronized fashion. BUILT-IN CLASS A AND B CIRCUITRY For the input and NAC circuits, the choice of Class A or Class B supervision is made at site on the board itself by selecting the terminals used for wiring. Neither conversion boards nor additional hardware nor jumper selection is required for this purpose. AGENT RELEASING CIRCUITS (ARC) The two circuits can be programmed for activation by different inputs, with independent time delays and abort modes to fire combinations of two of the following releasing devices: • 1 or 2 Kidde Continuous and Momentary Solenoid Control Heads • 1 Kidde Actuator or Fenwal Initiator • 1 Factory Mutual Group A, B, D, E, F, G, I, J, or K Solenoid In other words, operating in tandem, the two circuits can release: • 1 or 2 Control Heads on ARC 1 and 1 or 2 Control Heads on ARC 2 • 1 or 2 Control Heads on ARC 1 and 1 Actuator/ Initiator on ARC 2 or vice-versa • 1 or 2 Control Heads on ARC 1 and 1 FM Sprinkler Solenoid on ARC 2 or vice-versa • 1 Actuator/Initiator on ARC 1 and 1 Actuator/Initiator on ARC 2 • 1 FM Solenoid on ARC 1 and 1 FM Solenoid on ARC 2 This configurability is useful for those jurisdictions where the gaseous suppression agent is required to be supplemented with a pre-action system. TRIPLE-R PROTECTION FOR ARCS The two ARCs feature a triple failure redundancy safeguard system to protect them from inadvertent activation by the main microprocessor. The Triple-R system requires that in order to activate an ARC, the main microprocessor issues two release commands of opposing polarity via separate channels and that these commands be combined with a third signal from the panel watchdog timer to confirm the microprocessor operation. The Triple-R system ensures that electrical transients or disturbances such as power surges that could interfere with the operation of the main microprocessor will not inadvertently activate the connected suppression system. The result is a more robust and reliable suppression-focused panel. PROGRAMMABLE RELAYS Of the 4 relays, three are user-programmable for a variety of alarm related conditions and the fourth is a dedicated trouble relay. All relay contacts are rated 3.0 Amps at 30 VDC/120 VAC (resistive). POWER-LIMITED CIRCUITRY All circuits are inherently power-limited. ARCs can be configured for power-limited or non-power-limited operation. One in-line releasing device is required for each solenoid on a power limited ARC. In-line releasing devices are not included with the panel; the appropriate number of in-line releasing devices should be ordered using part number 06-220023-001. ROBUST POWER SUPPLY UNIT (PSU) The AEGIS 2.0 features a universal 120/240 V, 50/60 Hz AC Power Supply Unit with a robust 5.4 Amps of 24 VDC power. Input voltage selection is via a slider switch with no jumper cutting required. The on-board battery charger is able to charge 24 VDC (2 x 12) batteries of capacity up to 68 AH thereby allowing from 24 hours of supervision plus 5 minutes of alarm to 90 hours of supervision plus 10 minutes of alarm required by some jurisdictions. AUXILIARY POWER SUPPLY Up to 1 Amp of auxiliary power at 24 VDC is available to power external 4-wire devices such as Flame Detectors, AlarmLine modules, Duct Detectors, etc. The auxiliary power output is resettable. ELEGANT USER INTERFACE The user interface consists of an array of LED Indicators, Control Switches, a Digital Display, and Buzzer. Over and above the System, Power Supply status, Input circuit Fire and Trouble and Output circuit Trouble LEDs, the AEGIS 2.0 annunciates its suppression state-of-alarm via three additional Pre-Release, Releasing and Post Release LEDs. Four switches are provided, one each for Acknowledge, Signal Silence, System Reset and Output Disable. The 3-digit display provides a countdown of impending agent release. On command from the user interface switches, it also indicates the battery open circuit voltage and charging current. SIMPLE SITE-SPECIFIC CONFIGURATION Setting the site-specific configuration is easily done using the digital display and user interface buttons. To prevent unauthorized use, the configuration menu is protected by a user-changeable password. Factory technical support can provide assistance with lost or forgotten passwords. Apart from the input voltage selection performed on both the PSU and main board via a slider switch, no other onboard settings or jumper cuttings are required. EXTENSIVE DIAGNOSTICS Also initiated via the digital display and user interface switches, the troubleshooting function displays diagnostic codes that assist in determining causes of trouble. A complete list of diagnostic codes and their meaning ships factory installed on the inside of the enclosure door for easy reference. BACKWARDS COMPATIBILITY The AEGIS 2.0 is backwards compatible and listed for use with a full range of conventional detectors and alarm devices as well as suppression accessories from Kidde, Fenwal and Chemetron. Going forward, this will allow legacy panels to be replaced with relative ease. EASY TO INSTALL CABINET The cabinet design allows for easy installation by fitting between the studs of a standard 16 inch studded wall. It is large enough to house two 12 VDC, 12 AH Batteries and provides up to 2 inches (51 mm) of wiring and finger space between the circuit board and the cabinet wall. An optional door design features a Manual Release and Abort switch for applications with space constraints. Both switches incorporate guards that prevent their inadvertent activation.
