LPFE amplifier

The LFPE amplifier is used for the connection of IR2LF sensors to P1 or P2 PAGG fire control panels. It provides evaluation and monitoring of the IR2LF sensors. It indicates the operating conditions optically (10 alarm red LEDs and 10 trouble yellow LEDs) and transmits these to the downstream control centre.

Technical information LFPE amplifier

• Supply voltage: 15 to 35 V DC
• Enclosure: IP65
• Operating temperature: 0 °C to 50 °C
• Response time: 50 ms
• Inputs: 1 to 20 IR2LF sensors (according to the type of amplifier)
• Outputs: alarm (680R // 3K9) - trouble (opening of the line)
• Signalling: 10 Red LEDs for ‘Alarm’ - 10 Yellow LEDs for ‘Trouble’
• Current draw (depending on the numbers of sensors): Idle condition: 100 to 200 mA - Alarm: 50 to 300 mA - Trouble: 50 to 300 mA
• 4 stages for fire sensitivity, setting by dip-switch
• Vision impairment sensitivity adjustable by potentiometer
• Electrical connection by 7-pin plug
• Cable requirement: Flexible and shielded 4 x 0.5 mm2 cable - Yellow/green 6 mm2 earthing wire
• Reset by switching off the power supply
• Flame proof: II 3D 85°C
• Weight: approximate 2.5 kg
