NOTIFIER BDA Bi-Directional Amplifier Owner’s Manual

General

NOTIFIER offers all the components required for design and installation of the Emergency Radio Communication Enhancement Systems (ERCES): signal boosters/bi- directional amplifiers (BDA), batteries and battery enclosures, donor antennas, Distributed Antenna Systems (DAS), coaxial cables, connectors and lightning arrestors, power dividers and hybrid couplers, design services and training.

SIGNAL BOOSTERS / BI-DIRECTIONAL AMPLIFIERS (BDA)

NOTIFIER Class B BDAs are high gain, high power band-selective signal boosters /bi-directional amplifiers that can be designed and customized to meet all public safety frequency band ranges. It is intended to provide reliable two- way radio signal coverage inside buildings, tunnels and other structures. The band selective design delivers a reliable performance in even the most challenging RF environments.

Features & Benefits

All public safety frequency bands supported, various models available for:
- UHF: NF-BDA400-1B, NF-BDA400-2B
- VHF: NF-BDA150-1B
- 800 MHz: NF-BDA800-1B
- 700 MHz: NF-BDA700-1B
- 700MHz and 800MHz: NF-BDA7800-2B
UL, CSFM, NFPA, IFC compliance:
- All-inclusive and fully-integrated signal booster / BDA with UL2524 In-building 2-Way Emergency Radio Communication Enhancement Systems Listing, CSFM Listing, NFPA 72 2010 Edition, NFPA 1221 2016 Edition and IFC 2018 compliance.

- On board Diagnostics
- Donor antenna line monitored for integrity.
- Event history logging that can be exported.
- Optional Auxiliary Alarm.
- LCD displays BDA system status.
High Reliability
- Two high-efficiency power supplies are included for redundancy.
- Each module has an internal microcontroller that continuously monitors its operation and measures the voltage, temperature, current, and other parameters.
- RF power overload and RF interference prevention.
- Oscillation Detection Circuit prevents amplifier feedback.
- Automatic Uplink Squelch: Completely eliminates uplink noise from the BDA eliminating risk of interrupting public safety radio network.
Excellent RF Performance:
- Band/Channel-Selective modules provide high rejection of unwanted, interfering signals. Multiple channels/bands are possible within the same amplifier.
- High performance bandpass cavity-type duplexers minimize out of band interference.
- High Gain of up to 92dB on both uplink and downlink.
- High Power – capable of producing up to 32dBm of RF power.
- High Linearity Amplifiers deliver signals with very low distortion and low IM products.
- Highly Resilient to strong RF inputs – ensures optimal, intermod-free performance.
- Reliable performance even in high RF environments with signals as strong as -20dBm.
- Very low signal delay of <9us means no delay-produced RF distortion in the signal overlap areas.
- Optimized not only for FM and phase 1 P25 but also for TDMA and phase 2 P25 modulations.
- Adjustable RF gain on both LNA and ALC modules.
- Adjustable maximum power level.
- Multiple ALC/OLC circuits maintain the set power limit and prevent the power amplifier overload.
- Built-in EOL resistors are selectable with the DIP-switch.
Serviceability
- Modular Design with easy to swap and easy to test modules.
- Each module has a status indication LED light for easy troubleshooting and status monitoring.
- Easy to use gain and power settings.
- LED indication of signal strength.
- Convenient quick-disconnect terminals.
- Easily accessible RF connectors.
Expandability:
- Modular Design allows for easy updates and frequency band changes.
- Multiple boosters can be combined on the same antenna system for multi-band operation.
