What the Context Plus range at AZEIDK includes
For the brand itself, see our Context Plus brand page. This guide groups the products on AZEIDK’s product pages into six families:
| Family | What it includes | Typical use |
|---|---|---|
| Conventional panels | FP (1 to 14 zones), CFP (2, 4 and 8 zones), MFP (16 to 28 zones) | Small buildings and limited projects where zone indication is enough |
| Addressable panels | FirePlus (1 to 6 loops), ZFP (up to 8 loops, touchscreen), single-loop 16-zone and 32-zone panels | Projects that need the exact device identified and networking |
| Detectors | Addressable optical smoke and heat, beam, IR2 and IR3 flame, duct, carbon monoxide, aspirating, and Series 65A and 65E conventional | Matched to hazard, ceiling height and environment |
| Call points and alarm devices | Addressable call points with isolator (including waterproof), a dual-action pull station, resettable conventional call points, sounders, beacons, bells | Manual alarm and occupant warning |
| Interface units | Twin input/output unit and zone monitor with isolators, isolating bases | Links to other systems and short-circuit isolation |
| Specialized systems | EP203/CON gas extinguishing panel and accessories, SigTEL system | Gas suppression rooms, fire telephones, refuges |
Conventional or addressable: choosing within the range
Our guide to choosing a fire alarm control panel explains the general difference: a conventional system identifies the zone, an addressable system the device.
Conventional panels
FP panels cover 1 to 14 zones in metal enclosures, fixed or expandable (4 to 6 and 8 to 14 zones), with two sounder circuits and a one-person walk test on most models. The FP page lists compatibility with Series 65A, Series 65E and ActiV conventional detectors.
CFP panels come in 2, 4 and 8 zones with four sounder circuits and fire and fault relays, and a system supports up to eight two-wire repeater panels through one CFP761 card. For many zones, the MFP panel FF516/CON has 16 zones, expandable to 20, 24 or 28.
Addressable panels
FirePlus panels run from 1 to 6 loops, with up to 126 devices per loop and 64 zones, and several panels can be networked. The FirePlus page states support for the XP95 and Discovery protocols, so every loop device should use a protocol the panel supports. Its submittal certificate lists only the 1- to 4-loop models, so confirm coverage for 5- and 6-loop panels.
ZFP panels come in 1, 2, 4, 6 and 8 loop models with 40 zonal LEDs, a color touchscreen and printer and graphics options. A single-loop 16-zone panel, which its page describes as suited to medium-sized projects, can network with other XFP panels, and a single-loop 32-zone model is also listed.
Field devices and panel compatibility
A detector, call point or input/output unit works with the panel only if it uses a supported protocol and is listed to work with it. Some product names on AZEIDK’s pages point to different references: UL in the Series 65A detector and dual-action pull station names, EN54 in the Series 65E detector names.
Approval covers the specific model, not the series, so check each model’s certificate in its datasheet and do not mix references on one project without the consultant’s agreement. For detector types, see our fire detector selection guide.
Where components follow EN 54, check EN 54-2 (panel), EN 54-4 (power supply), EN 54-13 (system compatibility), EN 54-17 (short-circuit isolators) and EN 54-18 (input/output devices).
Isolators sit around the loop, as isolating bases or built into call points and input/output units. The isolating base disconnects the faulted side of a short while its own detector stays active, and restores power once the fault clears.
SigTEL fire telephones and areas of refuge
AZEIDK lists the SigTEL system within the Context Plus range for emergency voice communication and fire telephones. The ECU-8 master controller handles 8 lines, expanding to 16 with one ECU-8S unit, and up to four systems can be linked on a network of up to 1 km, for up to 64 lines.
- EVC301RPO Type A fire telephone outstation in a red steel cabinet, locking or non-locking.
- EVC302GS Type B disabled refuge outstation with true duplex communication to the control point.
- EVC301/PH roaming handset with EVC301/JP jack plate.
- Outstation wiring: 2-core 1.5 mm² enhanced fire-rated cable, up to 1 km.
On mains failure, the page states 24 hours standby and 3 hours in use on two 12 V 7 Ah batteries. Where the system is required and where outstations go is covered in our fire telephone and refuge guide, and our fire alarm cables and circuit integrity guide covers fire-resistant cable.
The EP203/CON gas extinguishing panel
The product page describes the EP203/CON as a three-zone automatic gas extinguishing panel with a graphical display and full release-sequence control, which can also act as a conventional fire alarm panel. Features include:
- Programmable zone combinations to start release; adjustable release delay, release duration and flooding time.
- Six monitored inputs, including hold and abort, a front-panel manual release, and two keyswitches, for function access and for automatic or manual mode.
- Two first-stage and one second-stage sounder circuits, and relays for fire, local fire, both stages, extractor fan and fault.
- RS485 links to up to eight remote status units, such as EP210F, EP210S and EP211, plus hold and abort buttons and yellow release call points.
Manual release, hold, abort and warning requirements follow the adopted standard, as our National Fire Protection Association (NFPA) 2001 guide explains.
Networking and integration with other systems
The FirePlus page lists a ULP-NIC two-wire network card, a SmartTerminal repeater, a ULP-HLI high-level interface with RS232, RS485 and Modbus outputs, and an MB3170 serial-to-Ethernet gateway for local and wide area network links. CFP and MFP each support up to eight repeaters.
The twin input/output unit with isolator has two circuits, each supervising normally open volt-free contacts and carrying a changeover relay rated 1 A at 30 V. Typical uses, set in the approved cause and effect matrix, are air conditioning shutdown, smoke extraction, door release and elevator recall. See our guides to building management system integration and voice evacuation systems.
If the panel joins the building network through a gateway, review cybersecurity: NFPA 72 (2025) moved cybersecurity provisions into Chapter 11 and added a maintenance plan for network-connectable equipment, where that edition applies.
Step-by-step: programming and commissioning
- Fix the design basis: the reference standard and edition (NFPA 72, or BS 5839-1 with EN 54 components), as the Saudi code, Civil Defense and the consultant set.
- Choose models and confirm each one’s certificate and compatibility with the panel protocol.
- Design loops for device count, current, cable length and size, and isolator positions; the FirePlus page states up to 500 mA per loop and up to 1 km on 1.5 to 2.5 mm² cable.
- Size batteries from standby and alarm loads and the adopted standard’s durations, within the panel’s capacity (up to 24 Ah for FirePlus).
- Prepare the cause and effect matrix with the consultant: alarm, evacuation, air conditioning shutdown, door release, elevators and gas suppression.
- Program in ConfigManager Plus or at the panel, with device text naming floor and room.
- Commission: test every device, every isolator with a deliberate short, every matrix output, every SigTEL outstation with a live call, and the gas release sequence with actuators disconnected.
- Hand over as-built drawings, the configuration backup, passwords and test records.
Maintenance and common mistakes
The adopted standard sets inspection and test intervals. Typical tasks: reviewing the event log, testing detectors and call points in rotation, checking batteries and charger, testing matrix outputs and SigTEL outstations, and testing the EP203/CON sequence without releasing agent.
- Mixing protocols or references on one loop.
- Long or crowded loops with no current or voltage drop calculation.
- Too few isolators, so one short takes out a large part of the system.
- An untested cause and effect matrix, vague location text, or no configuration backup for the owner.
- Standard cable on circuits that must survive a fire, such as SigTEL lines.

FAQ
How many devices can a FirePlus loop take?
The product page states up to 126 devices per loop and 64 zones, with up to 500 mA loop current and loops of up to 1 km on 1.5 to 2.5 mm² cable. The practical limit comes from current, voltage drop and isolator calculations, so calculate before filling a loop.
Can a Context Plus panel connect to a building management system?
Yes. The FirePlus page lists the ULP-HLI interface with RS232, RS485 and Modbus outputs and the MB3170 Ethernet gateway. Define scope and responsibilities in the cause and effect matrix, keep alarm and evacuation in the fire system, and review cybersecurity if the panel joins the building network.
How is the EP203/CON release sequence tested without discharging gas?
It is good practice to disconnect the release actuators as the suppression system manufacturer instructs, then run the sequence from each zone combination and the manual release, checking both sounder stages, the release delay, hold and abort, the extractor fan relay and the remote status units, and to record the results.
What should the owner receive at handover of a Context Plus system?
As-built drawings, the panel configuration and its backup, passwords, and test records for every device, isolator, cause and effect output and SigTEL outstation. Without the backup and passwords, later changes depend on the original installer, so it is good practice to make them a condition of handover.
Is a well-known brand enough to get the system approved?
No. Approval covers the specific model, not the whole series, and one certificate may not cover a whole family. Submit each model’s certificate and datasheet; the consultant and Civil Defense then review the design and installation against the reference standard and edition set under the Saudi Fire Protection Code.
