The 9955 RFX is a Class 6 Radio Expander designed to integrate wireless detectors and transmitters with 9750 or 9850 alarm systems. It supports up to eight radio detectors and up to six telecommands or PA transmitters. The RFX communicates with the control panel using the same wiring as remote keypads, and its radio detectors operate on 868.6625MHz.
Function Description:
The RFX acts as a bridge between wireless security devices and the main control panel. Each radio detector and remote setting device has a unique digital identity code that the RFX "learns" during installation, ensuring it only responds to authorized devices. The unit features a 2x7 segment display, select and delete switches, green "Pass" and red "Fail" LEDs for signal strength indication, and a sounder. It also includes jumpers for jamming response, supervision, and an address jumper, as well as a tamper switch and a learn sensor.

Usage Features:
- Installation: Involves a radio site survey to determine the best RFX position, cabling to the control unit or keypad, fitting the RFX case back, connecting the RFX, and learning wirefree detectors.
- Site Survey: Requires a 747rEUR Go/No Go test meter and a 746rEUR test transmitter. The test transmitter sends messages every 3.5 seconds (shuts down after 30 minutes). The test meter indicates adequate signal strength with a green "Go" LED (hold for at least 5 seconds) or weak signal with a red "No Go" LED.
- RFX Siting: Should be in a convenient location to connect to the control unit/keypad, within the protected area, and with clear space around it for good radio signal reception. Avoid siting outside the alarm area, near ground level, close to large metal structures (doors, frames, water tanks, cars, fridges, freezers), within one meter of mains wiring or metal pipes, inside steel enclosures, or next to high voltage/electronic equipment (computers, photocopiers, other radios).
- Learning Mode: The RFX enters learn mode when power is applied for the first time with the lid removed, displaying "88" then "- -" with a double beep. To return to learn mode, remove the lid and press Select.
- Learning Transmitters: Place the transmitter's activity LED within 100mm of the RFX's Learn sensor and activate the transmitter (or tamper on detectors). A double beep indicates successful learning. The display shows the total telecommands learned (e.g., "52") alternating with signal strength for PAs/telecommands, or zone number alternating with signal strength for detectors. A single low tone indicates failure to learn.
- Learning Detectors to Specific Zones: In learn mode, press Select to cycle through zone numbers. A steady display means a detector is already learned; a flashing display means the zone is free.
- Deleting Detectors: In learn mode, select the zone number and hold Delete for four seconds. The RFX will double beep and display "- -".
- Deleting Telecommands/PA Transmitters: In learn mode, press Select until the left digit shows " ". Hold Delete for four seconds. This deletes ALL telecommands and PAs.
- Displaying Received Signal Strength: In learn mode, select the zone or PA/telecommand count. Activate the device. Green Pass LED indicates strong signal, red Fail LED indicates weak. Signal strength 2 is the minimum for a reliable signal.
- Jamming Detection: With the jamming response jumper enabled, the RFX reports a fault if it detects radio noise strong enough to swamp detector signals for at least 30 seconds.
- Supervision: With the supervision response jumper enabled, the RFX reports a detector as faulty if no transmission is received for more than 2.5 hours.
- Detector Low Battery: The RFX reports low battery signals from radio detectors to the control panel.
Maintenance Features:
- 715r PIR Installation: Mount between 1.8 and 2.4 meters high. Avoid mounting facing heat sources (fire, boiler, window, radiator), near the floor, close to metal structures, within one meter of mains wiring/metal pipes, inside steel enclosures, or near electronic equipment.
- 715r Lens Changing: Remove PCB and sensor funnel, unclip old lens, insert new lens. Pet alley mirror can be swung down to delete all but the top row of detector zones (mount at 2m height for pet immunity up to 10m).
- 715r PIR Testing and Lockout: Normal use includes a three-minute lockout timer to save battery. For testing, the lockout period changes to 10 seconds for the first half hour after battery insertion or tamper trigger.
- 715r Wall Tamper: Cut out the large circle in the case back, drill and plug a hole for an M3 (No 4) screw (protruding no more than 2.5mm) to engage the tamper switch.
- 715r Corner Wall Tamper: Use Scantronic Corner Wall Tamper Bracket (Part No. 235385).
- 715r/719r/725r/735r Battery Replacement: If the activity LED shows a continuously pulsing glow for 30 seconds, the battery is exhausted or there's a fault. Replace batteries with specified types (AA for 715r, AAA for 719r/735r, DL 1/3N for 725r). Ensure correct polarity. If pulsing continues, return the unit for service.
- 726r PA Battery: Lithium cell is permanently soldered; return the unit to Cooper Security Service Department for replacement if the battery fails.
- 735r Universal Transmitter Siting: Mount the body on the non-moving frame of a door/window, and the magnet on the moving part. Ensure less than 10mm gap and magnet alignment when closed. Avoid hinged edge, floor, metal structures, mains wiring/metal pipes, steel enclosures, or electronic equipment.
- 735r Internal Reed: Remove link "LK1" to use only the internal reed switch. Remake the link to connect wire-in contacts.
- 735r External Door Contacts: Connect Normally Closed devices in series to the Alarm and Tamper connectors. Ensure "LK1" is fitted. Maximum 10m total cable length. If external contacts are removed, replace wire links and remove "LK1" to use the internal reed switch.
- 719r Smoke Detector Battery: The smoke detector has its own battery and two AAA batteries for the transmitter. The transmitter reports its own low battery, but not the smoke detector's battery low status to the control panel.
