Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 6 of 86 2. SAFETY CONSIDERATIONS 2.1 Earthing of Equipment Cell Enhancers supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations. 2.2 Electric Shock Hazard Electrical shocks due to faulty mains driven power supplies. Whilst ever potentially present in any electrical equipment, such a condition would be minimised by quality installation practice and thorough testing at: a) Original assembly b) Commissioning c) Regular intervals, thereafter. All test equipment to be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection.2.3 RF Radiation Hazard RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to AFL’s equipment, must be considered a safety hazard. This condition might only occur in the event of cable disconnection, or because a ‘spare’ output has been left un-terminated. Either of these conditions would impair the system’s efficiency. No investigation should be carried out until all RF power sources have been removed. This would always be a wise precaution, despite the severe mismatch between the impedance of an N type connector at 50, and that of free space at 377, which would severely mitigate against the efficient radiation of RF power. Radio frequency burns could also be a hazard, if any RF power carrying components were to be carelessly touched! Antenna positions should be chosen to comply with requirements (both local & statutory) regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is capable of producing RF field strengths, which may exceed guideline safe values especially if used with antennas having appreciable gain. In this regard the use of directional antennas with backscreens and a strict site rule that personnel must remain behind the screen while the RF power is on, is strongly recommended. Where the equipment is used near power lines or in association with temporary masts not having lightning protection, the use of a safety earth connected to the case-earthing bolt is strongly advised.
Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 7 of 86 2.4 Chemical Hazard Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by contact. Products that contain beryllium are load terminations (dummy loads) and some power amplifier transistors. These products can be identified by a yellow and black “skull and crossbones” danger symbol (shown above). They are marked as hazardous in line with international regulations, but pose no threat under normal circumstances. Only if a component containing beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the formation of dust. Any dust that has been created will be contained within the equipment module as long as the module remains sealed. For this reason, any module carrying the yellow and black danger sign should not be opened. If the equipment is suspected of failure, or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal. To return such equipment, please contact the Quality Department, who will give you a Returned Materials Authorisation (RMA) number. Please quote this number on the packing documents, and on all correspondence relating to the shipment. PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation barrier. This material should never be heated to the point where smoke or fumes are evolved. Any person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes should seek medical attention.2.5 Laser Safety General working practices adapted from EN60825-2: 2000 “Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or connector faces or point them at other people.” “Use only approved filtered or attenuating viewing aids.” “Any single or multiple fibre end or ends found not to be terminated (for example, matched, spliced) shall be individually or collectively covered when not being worked on. They shall not be readily visible and sharp ends shall not be exposed.” “When using test cords, the optical power source shall be the last connected and the first disconnected.” “Use only approved methods for cleaning and preparing optical fibres and optical connectors.” Always keep optical connectors covered to avoid physical damage Do not allow any dirt/foreign material ingress on the optical connector bulkheads. The optical fibre jumper cable maximum bend radius is 3cm; any smaller radii may result in optical cable breakage or excessive transmission losses. Note: Not all AFL products use fibre optic units and they are NOT weather proof. 2.6 Emergency Contact Numbers The AFL Quality Department can be contacted on: Telephone +44 (0)1494 777000 Fax +44 (0)1494 777002 E-mail qa@aerialfacilities.com
Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 8 of 86 3. EQUIPMENT OVERVIEW 3.1 System Description The New York Justice Centre needs three different frequency bands of radio coverage within its designated areas, each having specific channel allocations, some of which are simplex type, i.e. Tx & RX on a single frequency, and some duplex where the Tx & Rx are on two different frequencies so that both parties may transmit (or receive) simultaneously. The AFL equipment supplied for this task is in several different parts: VHF Channel selective Cell Enhancer 150MHz band, 5 channels (50-146501) UHF Channel Selective Cell Enhancer 400MHz band, 6 channels (50-146601) 800MHz Channel Selective Cell Enhancer 800MHz band, 2 channels (50-146701) Multi-Band Combiner All three frequency bands (80-146705) All the cell enhancers have two switched attenuators in each path, a 0-30dB device to adjust the signal level entering the channel selective module, and a 0-15dB unit which varies the output power (after the channel module) that drives the leaky feeder antennas. In this way the system may be finely tuned to both receive and transmit at the correct levels. Each cell enhancer will be described separately in this document but where enhancers have common modules, these will be detailed only once. An alarm system is fitted that monitors all active devices and is easily integrated into any series ‘loop’ type system (where any break will trigger an alarm and show a local fault LED in the area where the fault originated).

SYSTEM DETAILS 4.1 VHF Channel Selective Cell Enhancer Rack (50-146501) 4.1.1 VHF Cell Enhancer Rack Description The VHF cell enhancer, built into ten 19” wide shelves and housed in a 43U high equipment rack, is a mixture of simplex (Tx & Rx on one frequency) and duplex (Tx & Rx on two separate frequencies) systems, three simplex and two duplex. There are separate Rx and Tx antennæ for the VHF and UHF bands and a composite antenna for the 800MHz bi-directional system. All VHF input channels, up and downlink are selected by narrow band crystal filters, and all outputs have ferrite isolators fitted in series to increase the isolation between adjacent channels and protect the transistors of the power stages from possibly damaging reflections. Each active module has a volt-free relay contact pair alarm which is looped to provide a normally-closed system. The inputs and outputs are handled by combining and splitting shelves and the channel processing and amplification is all within the BDA channel shelves. The simplex Tx/Rx system relies upon noise-free paths to enable accurate detection and muting to occur and for this reason it is not recommended to disturb these circuits as they are carefully set up by AFL when system tested and should not be adjusted except by expert personnel. A dedicated power supply shelf provides the DC needed by the VHF system, (a similar power supply is used in the UHF system also), and all alarms are volt-free relay contact pairs, looped in each shelf to provide a summary alarm with local failure indicator, suitable for integration into any such existing system. No battery backup is provided for this system and so should the mains supply fail, this system could not function. 4.1.2 VHF Cell Enhancer Rack Electrical Specification PARAMETER SPECIFICATION153.965MHz* (Ch. 1) 154.755MHz154.785MHz154.980MHz158.925MHz* (Ch. 2) VHF downlink 151.355MHz* (Ch. 1) 154.6575MHz* (Ch. 2) 154.755MHz154.785MHzVHF Frequencies:154.980MHzVHF uplink Bandwidth: 15kHz (up & downlink) Downlink Gain(Duplexed): 97 dB min Downlink Gain(Simplex): 97 dB min Uplink Gain (Duplex & Simplex): 100 dB min Gain Adjustment: 0 – 15dB (in 1dB step) Uplink Power: >2-5Watts Downlink Power: >10Watts AGC: Fitted in all channel selective modules Noise Figure: <6dB (@ maximum gain) VSWR: better than 1.5:1 Impedance: 50ȍRF Connectors: N type, female Supply voltage: 110V AC (nominal) @ 43-63Hz System power requirement: 24V DC @ <13A 1 Amplifiers Alarms Fitted: (volt-free contacts/TTL) 2 PSU * = duplex channel

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 13 of 86 4.1.5.1DescriptionThe five (downlink) channels are received from the output ports of the individual bi-directional amplifier shelves and coupled together through hybrids, except for channel 2 which, being a substantially higher frequency than the other four, has its own path through a dedicated bandpass filter at the output of which the other four combined frequencies and channel 2 meet. The single signal path is then passed through a divider to two equal level downlink output ports, VHF1 & VHF2.

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 16 of 86 4.1.6.1DescriptionThis shelf receives the single uplink RF from the antenna(s) and, similar to the downlink, one of the five channels is substantially different in frequency to the other four. This means that channel 1 is routed through a dedicated bandpass filter and the other four signals together also use a single filter. The output of this ‘four-way’ signal path is then split to four individual crystal filters, which, together with channel 1 path form the five uplink inputs to the five VHF amplifying shelves. Channel 1 signal needs no crystal filter as its single bandpass filter is tuned to a much narrower bandwidth to the filter in the other path containing the ‘four’ frequencies. This is a passive shelf and has no connection to the PSU and no alarms 4.1.6.2Technical Specification PARAMETER SPECIFICATIONHeight: 3U Width: 19" (482.6mm) Shelfdimensions: Depth: <450mm (excluding connectors & handles) operational: -20°C to +60°C Temperaturerange: storage: -40°C to +70°C Weight: <10kg Frequency ranges passed: 153.965 to 154.980 & 158.925MHz Impedance: 50ȍHumidity: 5 – 95% non-condensing RF Connectors: N type female Environmental protection: IP44 Case: Iridite NCP coating Heatsinks: None Handles: Silver anodised aluminium alloy FinishFascia: Painted to RAL7035 4.1.6.3Parts List AFL Part # Part Description Qty.01-003105 SD NOTCH FILT.N 6 SECT.VHF H/B SMA 2 19-000922K 3U CHASSIS KIT (450mm deep) 1 91-030002 N ADAPTOR PANEL FEMALE:FEMALE 6 91-130001 SMA ADAPT 'T' ALL FEMALE 3 GHz 4 93-980195 154.755MHz CRYSTAL FILT FAN4M52500 1 93-980196 154.785MHz CRYSTAL FILT FAN4M52500 1 93-980197 154.980MHz CRYSTAL FILT FAN4M52500 1 93-980198 154.6575MHz CRYSTAL FILT FAN4M52500 1

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 25 of 86 4.1.9.1DescriptionThe simplex channel amplifier shelves (x3) receive their input signals from antennas and are processed as follows:- The Simplex controller module (17-015301) monitors the receiver output for a signal change and activates the supply switching for either the uplink or down link path accordingly. In normal operation, the low level Rx path is activated and the associated Tx path is switched off. When a signal is detected by the downlink channel selective module, the Rx output goes low, which triggers the controller logic PCB. The PCB mutes the power supply to the opposite path Rx LNA’s and switches on the power to the output power stage. In order to prevent the power stage noise blocking the opposite path’s low level receiver, the power amplifier is normally muted. Both outputs are protected by ferrite isolators in a similar way to the duplex shelves. All three simplex shelves are hardware similar so only channel 3A shelf is described. 4.1.9.2Technical Specification PARAMETER SPECIFICATIONHeight: 3U Width: 19" (482.6mm) Shelfdimensions: Depth: <450mm (excluding connectors & handles) operational: -20°C to +60°C Temperaturerange: storage: -40°C to +70°C Weight: <10kg 154.785MHz (Ch. 3A)154.755MHz (Ch. 3B) Channel frequencies:154.980MHz (Ch. 4) Shelf gain: 100dB (typical) Impedance: 50ȍHumidity: 5 – 95% non-condensing RF Connectors: N type female Environmental protection: IP44 Case: Iridite NCP coating Heatsinks: Black anodised Handles: Silver anodised aluminium alloy FinishFascia: Painted to RAL7035

Bronx Justice Centre Radio Repeaters Handbook Number: 80-283501HBKM Page: 41 of 86 4.1.14.1 VHF/UHF PSU Shelf Description The power supply shelf consists of two, 400Watt 24V DC O.E.M modules which are commonly supplied from the mains but separately switched. The DC outputs are separately monitored and this data becomes half of the alarm data for the shelf (the two monitor loops are summed to form a single alarm relay contact pair). A pair of low-loss power diodes combine the outputs from the PSU modules in a redundant configuration such that if either module fails, the other supply would still be active but the faulty supply’s DC LED on the front panel would be extinguished and the alarm loop would be broken.4.1.14.2 VHF/UHF PSU Shelf Technical Specification PARAMETER SPECIFICATIONHeight: 5U Width: 19" (482.6mm) Shelfdimensions: Depth: <450mm (excluding connectors & handles) operational: -20°C to +60°C Temperaturerange: storage: -40°C to +70°C Weight: <10kg Humidity: 5 – 95% non-condensing DC Output connectors: 6 x XLR female DC Output Voltage: 24V DC (x 6) 24V DC O/P fuse rating: 10A (x 6) Environmental protection: IP44 Alarms: PSU1 & 2 (‘D’ connector pins 1 & 2) Case: Iridite NCP coat Heatsinks: Black anodised aluminium Handles: Silver anodised aluminium alloy FinishFascia Painted to RAL7035
