Establish the alarm boundary
For a Greenwich alarm enquiry, explain whether you are protecting a whole house, a flat or a commercial unit. Include common entrances separately from private rooms. A visitor or another occupier using shared space should not leave uncertainty about which part of the alarm you are responsible for operating.
Tell us about the entrances you normally use, rooms occupied overnight and any change of use since the existing installation. The design conversation should follow the actual routine rather than an assumed standard floor plan.
Consider the individual building
Greenwich has published conservation and listed-building information. Where restrictions apply to your address, raise them before external equipment and cabling are agreed. That does not imply every building has the same constraints; the relevant information is specific to the property.
If equipment is being retained, ask how its suitability and condition will be assessed. A new control panel does not automatically establish that the existing detection layout meets your requirements. Provide any available system paperwork and written insurer conditions so the proposal can be considered with those details known.
Make monitoring and ownership explicit
Ask what happens after an activation and who is expected to respond. Monitoring and maintenance are separate service decisions and should have clear scopes and costs. Arrange the operating demonstration with the people who will use the alarm regularly. If the installation is for a managed building or business, identify who keeps records, changes user access and arranges servicing after handover.
