1.General Information >30cm Transmitter Ensure clear line of sight from Receiver to Transmitter >30cm Receiver 5 - 120m Power Supply Unit Controller • IMPORTANT NOTE: The infrared beam path MUST be kept clear of obstructions at all times! Failure to comply may result in the system initiating a Fire or Fault signal. • All installations should comply with local regulations • For installations approved to UL 268 refer to NFPA 72 for installation guidance.

4. Apply Power NOTE: One System Controller can be used to control and monitor up to two Receiver heads. The ‘#’ symbol in this guide is used to represent the number of the Receiver currently selected (1 or 2).

. Select Receiver to be Accessed • All Receivers need to be aligned separately • Steps 8 and 9 explain how to align individual Receivers 2- 1- 8. LASER Targeting • The LASER in the Receiver head is used to align the Receiver with the Transmitter. • The LASER can be activated using the button on the Receiver head whilst in Engineering Menu, or via the LASER icon in the ENGINEERING MENU as shown below.
9. Alignment Step 1 In installation mode you are centring the Transmitter beam onto the Receiver and the system is adjusting its power for optimum signal. Step 2 Set Tx power to maximum. Tx NOTE 1: Value can be between 2 and 178. A higher value means a better alignment.
From Step 3 Step 4 Tx Green - flash/stop (SEE NOTE 1) Rx (SEE NOTE 1) Signal increased LED - no flash LCD = between 2 and 178 Tx Amber - flash/stop View LEDs on Rx or LCD value Green - flash/stop Reduce Tx power NOTE 1: Value can be between 2 and 178. A higher value means a better alignment. Adjust one thumbwheel by 1/4 turn. Tx Green - short/long flash LCD = 180 Adjust same thumbwheel by 1/4 turn in the same direction. Release thumbwheel and wait 1 second.
. Manual Fire and Fault Tests After installation or cleaning, it is recommended that a Manual Fire and Fault test is performed: Fire Test: Slowly half-cover the Receiver. The Controller will indicate Fire after the Fire Delay Time. Uncover the Receiver. The Controller will return to Normal state after approximately 5 seconds. Fault Test: Completely cover the Receiver taking less than 2 seconds to do so. The Controller will indicate Fault after the Fault Delay time. Uncover the Receiver.
12. Fire Threshold This setting is the threshold at which the Receiver will detect a fire. Default factory setting=35%. (Set for each Receiver). • Sensitivity can be adjusted in 1% steps by pressing up or down keys • Press to accept setting UL268 Fire Threshold Ranges: Distance betweenTransmitter and Receiver Fire Threshold Range 10 - 20m (32.8 - 65.6 ft ) 25 - 30% 5 - 10m (16.4 - 32.8 ft ) 25% 20 - 40m (65.6 - 131.2 ft ) 25 - 45% 40 - 60m (131.2 - 196.8 ft ) 60 - 80m (196.8 - 262.
13. Delay To Fire This setting is the delay the System Controller uses before signalling a FIRE condition to the Fire Control Panel. Default factory setting=10 seconds. (Set for each Receiver). 14. Delay To Fault This setting is the delay the System Controller uses before signalling a FAULT condition to the Fire Control Panel. Default factory setting=10 seconds. (Set for each Receiver). 15. Latching/Non-Latching Mode In Latching Mode the system will stay in Fire condition after the fire clears.
16. Cleaning The System The system will automatically compensate for dust build-up by changing the Compensation Level. However, it is recommended that the Receiver lenses are cleaned periodically with a soft lint-free cloth. The system should be isolated from the Fire Control Panel before cleaning takes place. After cleaning, verify that the system is operating normally by following the Alignment procedure and the Fire and Fault Tests described in this User Guide.
