Electrical Description
The Intelligent Auto Aligning Beam Detector is loop-powered and requires no external power supply.
Each beam detector draws 10mA or less in quiescent and 36mA in alignment mode, from the analogue addressable loop and, unless proven by calculation**, it is recommended that no more than ten beam detectors be powered from each loop. A recommended 2-core fire rated cable should be used for connection between the controller and the detector head.
** A loop voltage drop calculation program, known as ‘Loop Calculator’, has been developed by Apollo for use by system designers and is available as a free download from the Apollo website (www.apollo-fire.co.uk)
Operation
The Intelligent Auto-Aligning Beam Detector is a compact detector for detecting smoke in large open areas such as warehouses, theatres, churches and sports centres. It comprises a ground level loop-powered controller, a detector head with an operating range of 8m-50m and a single prism. The operating range of each detector head can be increased, up to 100m by using the Extension Kit, which comprises of three additional prisms. An additional detector head can be connected to the controller. Each head has a loop address. It also has a built in 20T negative bi-directional short circuit isolator, and it is compatible with control panels using CoreProtocol, Discovery and XP95 protocol.
A built-in laser provides rapid initial alignment and thereafter the detector head will continuously automatically align and compensate for any building movement. The status of each detector can be monitored through the controller which is sited at ground level. The detector head operates both as a transmitter and a receiver. A well-defined IR beam is projected to a prism mounted on the opposite wall, which is reflected back to the receiver. In the event of smoke partially obscuring the light an imbalance between the transmitted and received light will occur. The detector will then transmit an alarm value to the control panel.
The detector is factory set to a beam obscuration of 35% which is the best setting for most factories and warehouses. The setting can be changed to 25% for offices and clean areas such as theatres or to 50% for hostile areas such as mills or foundries. The detector reports a pre-alarm (analogue value 48) at approximately 75% of the alarm threshold.
The detector compensates automatically for gradual contamination of the lenses in order to avoid false alarms. The detector is non-latching and resets 30 seconds after an alarm event ceases and in 3 seconds after the removal of a fault.

Device Addressing
Select the required address using address switches 1 to 7 for XP/Discovery and 1 to 8 for Soteria with core enabled panel. The reference table can be view on the Installation Guide (39215-002), address 127-254 relate only to Soteria. When only one detector is connected it will appear on the address set on the DIP switch. When there are two detectors connected then detector 1 will appear on the selected address and detector 2 will appear on the selected address +14.
Backward Compatibility
XP95, Discovery and CoreProtocol compatible
Product Information
The Intelligent Auto-Aligning Beam Detector combines a transmitter/receiver in the same detector head with an automatic alignment motor. This combination with integrated addressability allows for quick and simple installation. The Intelligent Auto-Aligning Beam Detector automatically compensates for environmental effects on the beam signal, keeping the unit in the best possible working order. This is achieved through the combination of software (automatic gain control) and motorised realignment of the beam.
