System Sensor B114LPBT 24VAC/DC Plug-In Base for 2151 Duct Smoke Detector

Duct smoke detection in low-flow air handling systems often calls for a pendant-mounted head. The System Sensor B114LPBT is the 24VAC/DC plug-in base that makes this possible with the 2151 Special Applications Duct Smoke Detector. It is designed for 4-wire systems and includes terminals for alarm and supervisory relays and a remote annunciator.

• 24 VAC/DC system voltage for 4-wire applications
• Form A and Form C alarm relay contacts plus a Form A supervisory relay
• Terminals for remote annunciator and remote test coil connections
• Twist-in/twist-out head for quick cleaning and maintenance
• Mounts to 4\" square, 4\" octagon or 3 1/2\" octagon boxes (1.5\" min. depth)

• Manufacturer: System Sensor
• Part Number: B114LPBT
• System Voltage: 24 VAC/DC, 60 Hz
• Relay Ratings: Form A 2.0 A @ 30 V AC/DC; Form C 2.0 A @ 30 V AC/DC, 1.0 A @ 125 VAC
• Standby Current: 25 mA typical @ 24 V (base and detector)
• Alarm Current: 75 mA typical @ 24 V (base and detector)
• Operating Temperature: 32°F to 120°F (0°C to 49°C)
