Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic cost calculation that includes all direct costs (equipment, labour) and indirect costs (overheads, profit margin) for supply and installation.
- Credit evidence that shows the learner accurately interprets design specifications and site survey data to produce a quotation aligned with system requirements.
- Ensure the learner includes maintenance cost calculations covering periodic inspections, reactive call-outs, and compliance testing in accordance with relevant standards (e.g., BS 5839, BS EN 50131).
Assessment Guidance
Guidance for achieving higher grades
- 💡Ensure your quotation templates are fully itemized, showing separate line items for parts, labor, and any subcontractor work, with clear reference to manufacturer price lists or supplier quotations.
- 💡Include a risk assessment and method statement (RAMS) as part of your quotation evidence to demonstrate safety awareness.
- 💡Cross-reference your cost calculations with industry-recognized cost databases or supplier quotes to validate pricing.
- 💡Always quote the relevant British Standard number and clause when answering questions about system design or installation. This shows you understand the regulatory framework.
- 💡For calculation questions, show all steps and include units. Even if your final answer is wrong, you can gain marks for correct method and intermediate values.
- 💡When describing commissioning procedures, mention specific tests like 'end-of-line resistance check', 'alarm verification', and 'battery capacity test' to demonstrate practical knowledge.
Common Mistakes
Common errors to avoid in your coursework
- Failing to account for all regulatory compliance costs, such as certification or documentation fees, leading to underpriced quotes.
- Misinterpreting client requirements, resulting in incorrect system specifications and subsequent quotation errors.
- Overlooking hidden costs like travel time, tooling, or disposal of old equipment.
- Misconception: All fire alarm systems require the same type of detector. Correction: Detector choice depends on the environment (e.g., smoke detectors for general areas, heat detectors for kitchens, flame detectors for high-risk areas).
- Misconception: Intruder alarm systems only need to detect entry. Correction: They must also detect tampering (e.g., cover removal, line fault) and provide signalling to an alarm receiving centre (ARC) for monitored systems.
- Misconception: CCTV cameras can be installed anywhere without planning. Correction: Placement must consider privacy laws (GDPR), coverage requirements, and lighting conditions to ensure effective surveillance.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A fire alarm system is designed for a three-storey office building. The ground floor is open-plan (500 m²), first floor has 10 offices (each 20 m²), and second floor has a server room (30 m²) and storage (70 m²). Calculate the minimum number of manual call points required on each floor, assuming the building is Category L2. Show your working.
- 1.Step 1: Identify the requirement from BS 5839-1: Manual call points must be located on all escape routes and within 45 m of any point in the building. Also, on each floor, at least one call point must be at each exit to a stairwell.
- 2.Step 2: For the ground floor (open-plan 500 m²), calculate the maximum distance: 45 m radius from any point. Since the floor is open, one call point near each exit (typically 2 exits) is sufficient. However, check coverage: if the floor is large, additional call points may be needed. Assume 2 exits, so 2 call points minimum.
- 3.Step 3: For the first floor (10 offices, each 20 m², total 200 m²), each office has a door to a corridor. The corridor is an escape route. Place a call point at each end of the corridor and near the stair exit. Typically, 2 call points per floor for small floor plates, but here 3 call points (one at each end of corridor and one at stair exit) ensure coverage within 45 m.
- 4.Step 4: For the second floor (server room 30 m² + storage 70 m² = 100 m²), the server room may be a high-risk area. Place a call point at the exit of the server room and at the stair exit. So 2 call points.
- 5.Step 5: Total minimum call points: Ground floor 2, First floor 3, Second floor 2 = 7 call points.
Question: An intruder alarm system uses a Grade 2 control panel with 8 zones. The installer connects 6 passive infrared (PIR) detectors and 2 magnetic door contacts. Each PIR detector has a standby current of 15 mA and alarm current of 35 mA. Each door contact has standby current of 5 mA and alarm current of 15 mA. The control panel has a standby battery of 12V, 7 Ah. Calculate the maximum standby time (in hours) if the system is in alarm for 10 minutes per day. Assume the panel itself draws 100 mA in standby and 200 mA in alarm.
- 1.Step 1: Calculate total standby current: PIRs: 6 × 15 mA = 90 mA; Door contacts: 2 × 5 mA = 10 mA; Panel: 100 mA. Total standby = 90 + 10 + 100 = 200 mA = 0.2 A.
- 2.Step 2: Calculate total alarm current: PIRs: 6 × 35 mA = 210 mA; Door contacts: 2 × 15 mA = 30 mA; Panel: 200 mA. Total alarm = 210 + 30 + 200 = 440 mA = 0.44 A.
- 3.Step 3: The battery capacity is 7 Ah. However, the system must provide standby for a certain period plus alarm time. Assume the standby time is T hours, and alarm time per day is 10 minutes = 10/60 = 0.1667 hours per day. Over T days, total alarm time = 0.1667T hours. But the question asks for standby time in hours, so we consider a single cycle: standby for T hours, then alarm for 10 minutes. The total charge drawn = standby current × T + alarm current × (10/60). This must be ≤ battery capacity. So 0.2T + 0.44 × (10/60) ≤ 7. Calculate: 0.44 × (10/60) = 0.44 × 0.1667 = 0.0733 Ah. Then 0.2T ≤ 7 - 0.0733 = 6.9267, so T ≤ 6.9267 / 0.2 = 34.63 hours. But this is unrealistic because standby time is usually days. Actually, the battery must support standby for a specified period (e.g., 12 hours) plus alarm time. The question likely expects a simple calculation: total standby current 0.2 A, battery 7 Ah, so standby time = 7 / 0.2 = 35 hours. However, alarm current reduces it slightly. For a typical exam, they might ignore alarm time or assume it's negligible. But let's provide a precise answer: T = (7 - 0.44*(10/60)) / 0.2 = 34.63 hours.
- 4.Step 4: State final answer with units.
