2.10 Building Entry, Access and Security

An access control and door entry system is provided to the front and rear blocks at 155 Station Road, Sidcup. Currently there is a video entry panel fitted and access control doors fitted throughout the development.

The new system generally operates as follows:

Front Block – Block A

Entry by a Resident
The front entrance of the building is fitted with a door entry panel c/w with fob reader and keypad. When a resident of the private apartments presents his fob to the reader on the panel the system will release the lock to the external door only allowing entry to the building. This will permit the resident entry into the internal lobby. There is a second access controlled door between this area and the rest of the building to provide additional security and to try and prevent people tailgating residents into the building.

To gain access through the internal lobby door, the resident must present their fob to the reader. Both the main entrance door and internal lobby doors shall have the door release timed to 5–10 seconds (final timing to set during commissioning) and the doors will be on self closers.

Entry by a Visitor
When a visitor arrives at the building they will use the panel fitted on the front entrance to call the flat they are visiting. The system will dial the entry system of the resident they are visiting. The resident will be able to see and speak with the visitor via the video entry system. The resident can then buzz the visitor in through the external doors via their entry system and give the visitor access to the internal lobby area.

To gain access through the internal lobby door the visitor will then be required to call the flat they are visiting via second door entry panel fitted adjacent to the internal access controlled door. Again, the resident will then buzz the visitor through the door to gain access to the internal circulation areas of the building.

Entry by the Postal Worker
The postal worker will receive a fob to gain entry. The postal delivery person will have to present their issued fob to the reader to gain entry. The key fob shall only allow for the release of the mag lock to the external door to grant access to the first entrance lobby only (i.e. the fob will not be programmed to open the second internal lobby door). This shall allow the postal worker into the internal lobby to deliver any post to the associated letterboxes but stop them from accessing the rest of the development.

Leaving the Building
When leaving the building there is a green push to exit button fitted on the secure side of both the internal and external doors. When these buttons are pressed, the locks on these doors will release. There are self closers on these doors to return them to the closed position, where the magnetic locks will re-engage.

Front Block – Block B

Entry by a Resident
The front entrance of the Block B is fitted with a door entry panel c/w with fob reader & keypad. When a resident of the private apartments presents his fob to the reader on the panel the system will release the lock to the external door allowing entry to the building. This will permit the resident entry into the internal lobby. There is a second access controlled door between this area and the rest of the building to provide additional security and to try and prevent people tailgating residents into the building.

To gain access through the internal lobby door, the resident must present their fob to the reader. Both the main entrance door and internal lobby doors shall have the door release timed to 5–10 seconds (final timing to set during commissioning) and the doors will be on self closers.

Entry by a Visitor
Same process as Block A — call, video confirm, buzz in, repeat at internal lobby.

Entry by the Postal Worker
Same fob arrangement as Block A — access to first lobby only.

Leaving the Building
Green push to exit buttons and self closers, same as Block A.

Other Areas

The bin and bike stores will also have access controlled doors. A fob reader will be provided adjacent to the entry door to each of these rooms. Only the fobs programmed for the front block are capable of opening the bin store and bike store allocated to the front block residents (Block A). Likewise only the fobs programmed for the rear block residents (Block B) will be permitted to open the bin and bike stores allocated to the rear block.

Green push to exit buttons shall be fitted on the secure side of these doors to permit residents to leave without using their key fobs, thus preventing them from becoming locked within these rooms.

Adjacent to Block B bike store a key safe with digi lock shall be provided. The key safe shall hold a key fob fixed on a retractable cable which shall be programmed to open the Block B bin store only. The purpose of this is for the refuse collectors, as the local council will not accept key fobs but will accept an access code.

Other Features

The access control system in each building is linked to the fire detection system covering the communal areas. In the event of a fire being detected within a building then the access control system within that building will unlock (i.e. all locks will disengage) all electronic activated locks on doors within the building.

All locks are powered closed fail open. In the event of a power failure in the building all locks will fail open.

Access to the front and rear via the side passage

There is a side passage access between the high street and the rear of the development. There will be an access control door/gate restricting access to the passageway.

When a resident (from either Block A or B) presents their fob to the reader on the panel at either end of the passageway the system will release the lock to the external door/gate allowing access through this passageway. This will permit the resident to move around the development.

Once inside the passageway a green push to exit button on the internal side of the door will allow residents to exit this passageway.

Block A – Visitor
A visitor trying to transit from the rear of the development to the front block (Block A) will be able to use the south passageway. The access control panel located on the rear side of the south passageway can be used to call the flat they are visiting in the front block. The entry panel will dial the entry system of the resident they are visiting. The resident will be able to speak with and view the visitor. The resident can then buzz the visitor in via their system.

Upon leaving, a visitor will have to be accompanied by the resident (with their fob) or the visitor will have to walk around the block to reach the rear of the block because the door entry panel on the high street side of the south passage is not configured to call Block A flats.

Block B – Visitor
A visitor trying to transit from the High Street side of the development to the rear block (Block B) will be able to use the access control panel on the high street side of the south passage to call the flat they are visiting in the rear block. The entry panel will dial the entry system of the resident they are visiting. The resident will be able to speak with and view the visitor. The resident can then buzz the visitor in via their system.

Upon leaving, a visitor will have to be accompanied by the resident (with their fob) or the visitor will have to walk around the block to reach the high street because the door entry panel on the rear side of the south passage is not configured to call Block B flats.

Postal Worker
The postal worker will have a multi-programmed fob that will not only open the front doors to each block but will also open both the door and gate to the side passageway so they can access both buildings without the need to walk around to the rear via the road access.

Podium Roof Garden

Access out to the roof Podium Garden (at L2) is provided via an access control door from either Building A or Building B. Access is to be time controlled as well as via fob access. This is to prevent access late at night and discourage anti-social behaviour. When a resident presents their fob to the reader inside the door the mag lock will release and they will be able to access the podium garden. However, access will be time controlled to only provide access between 7am–10pm.

Residents from Block A and Block B will have their access restricted so that they can only open and utilise the access door from their associated blocks. This will prevent residents from Block A entering Block B via the roof podium and vice versa.

To leave the roof podium garden area the outside door will be fitted with a fob reader on the outside. The resident will present their fob to the reader and the door will open.

In the event of a visitor finding themselves on the podium garden without a key fob they have to use their phones to call the person they are visiting to get access back inside the building.

In the event of a fire alarm activation within a building then the access control system within that building will unlock (i.e. all locks will disengage) all electronic activated locks out onto the podium deck roof. All locks are powered closed fail open. In the event of a power failure in the building all locks will fail open.

In the event of an emergency on the roof, a green emergency escape break glass will be fitted on the podium side of the access controlled door which can override the access control system from the podium and permit access out of this area in an emergency. This break glass will be fitted with a cover and alarm to minimise accidental or malicious use.

The green break glass shall also be capable of automatically self-resetting after a period of approximately 6 minutes.
