Itemised interconnected smoke alarm installation costs
These 7 AUD lines reproduce the native app export. Alarm unit allowance is measured as 4 each; Bases and connection parts uses 1 set. Some lines are measured work while others are a product or site-task allowance. Read the unit before reusing the structure for a different job.
| Work item | Quantity | Unit rate | Amount |
|---|---|---|---|
| Position survey and plan | 1 job | A$296.10 | A$296.10 |
| Alarm unit allowance | 4 each | A$133.95 | A$535.80 |

| Handoff labels and cleanup | 1 job | A$141.00 | A$141.00 |
| Illustrative total | A$2,834.10 | ||
Product selection and installation should be clear from the descriptions. Confirm delivery, fixings, preparation, waste and any specialist trade responsibility for the actual job rather than assuming each allowance covers them.
Check the arithmetic
Alarm unit allowance: 4 each × A$133.95 = A$535.80. Bases and connection parts: 1 set × A$253.80 = A$253.80. All other lines use the same quantity-by-rate calculation and sum to A$2,834.10. Every fixture line lands on an exact cent, so the native PDF subtotal equals the displayed table total.
Measurement to check: Count rooms and alarm positions, record ceiling construction and interconnection route. Selection to check: Identify alarm units, bases and interconnection components separately. The PDF uses a 0% tax input only to make its fictional arithmetic visible. Confirm the GST treatment that applies to the actual job and set your own markup before sharing a client quote.
Assumptions and exclusions
Confirm the required local design with a qualified installer before setting the positions.
Outside this stated scope: No whole-building fire-system design, panel replacement or guarantee of regulatory compliance without review.
A missing circuit or inaccessible route changes installation method. A changed condition should lead to a newly measured quantity, revised allowance or separately agreed task. Keep the client informed of the changed figure before producing another PDF.
