02/04: Door entry wiring diagram 2 - fail safe, high power magnetic lock with CityLine/SkyLine/SlimLine
This connection diagram shows how to wire up a high-power (more than 350mA) electronic door lock using an external power supply with any of the CityLine, SkyLine or SlimLine range of door entry devices.
CityLine info.
SkyLine info.
SlimLine info.
Wiring Diagram (click to enlarge)
Parts Required
These can all be bought from ProVu.
- Any ProTalk CityLine, Skyline or SlimLine IP door entry kit
- 240Volt AC mains to 12Volt DC power supply (with internal battery back up highly recommended)
- A 12Volt "fail-safe" door lock - large magnetic lock shown in diagram
- A "push to break" exit switch
- "VHLD" - Very Handy Little Delay
Notes
- Mains voltage is dangerous! If you aren't 100% confident you know what you are doing, hire a qualified electrician (at least for the power supply installation)
- This set up is intended for use when you have large locks that require more than 350mA current or as a way of adding battery back up
- Whilst the door entry unit itself can be powered from PoE, it makes sense to use the same 12V power supply since it is installed and (hopefully) battery backed
- Make sure the power supply is more than capable of supplying enough power for both the lock(s) and the door entry unit
FAQ Question
Can you advise a compatible base station for SL910H
Answer
You have 3 options:
1) The most common one is N300IP. Supports 6 SIP accounts and 3 SIP calls.
http://www.provu.co.uk/gigaset-n300ip.html
2) If you need want an answering machine in the device, then you need N300AIP
http://www.provu.co.uk/gigaset-n300aip.html
3) if you need 4 SIP accounts, or POE then an N510.
http://www.provu.co.uk/gigaset-n510ip.html
In the future you will also be able to use these handsets with the N720 roaming dect system for up to 100 users.

This connection diagram shows how to connect a electronic door strike plate up to any of the CityLine or SkyLine IP door entry units we sell.
Wiring Diagram (click to enlarge)
Parts required
These can all be bought from ProVu
- Any ProTalk CityLine or SkyLine IP door entry kit
- A 12Volt "fail-safe" electronic door strike (max 350mA)
- A "push to break" exit switch
- "VHLD" - Very Handy Little Delay board
Notes
- Ensure the exit switch is push-to-break, not push-to-make, or this will not work
- If an emergency break glass is needed, connect this in series with the normal exit switch
- The Door Entry unit cannot supply more than 350mA from the 12Vout connector, do not attempt to use a door lock which will draw more power or you will damage the door entry unit (and void the warranty!). If you have a more powerful door lock then a separate power supply must be used (which I'll draw a diagram for soon).
- 12Vin is not shown connected as you can power the whole device & circuit from either this or Power-over-Ethernet.
- You can adjust the amount of time the door is unlocked for by setting the "delay" potentiometer on the VHLD board, anti-clockwise increases the delay.
I will be drawing a series of these diagrams to suit various scenarios so keep checking here for more.
16/03: Wall mountable phones

Wall mounting is perfect for corridors and communal areas such as kitchens and staff rooms. These are ideal to be used with SIP door entry phones, allowing you to answer the door even when you're not sat at your desk.
I have put together a guide below outlining our range of wall mountable phones:
| Brand | Phones | Mounting details |
|---|---|---|
| Yealink | T18P, T20P, T22P and T32G | By using the phones stand |
| snom | 300, 320, 360 and 370 | By using the phones stand | snom | 720, 760 | Direct to the back of the phone |
| snom | 821 and 870 | Wall mounting bracket required (Snom-800Wall) |
| Aastra | 30i, 31i, 35i, 37i, 39i, 55i and 57i | Wall mounting bracket included |
| Cisco | 301G, 303G, 502G, 504G and 525G2 | Wall mounting bracket required (MB100) |
| Gigaset | DE310 and DE410 | Wall mounting bracket included |
| Gigaset DECT | A510H, C300H, C610H, E49H and S810H | Direct to the back of the cradle |
15/03: Door Entry Demo Kits
In order to properly demonstrate what our door entry kits look like and what they can do, I've turned my hand to a bit of metalwork and woodwork to make these display stands:

If you are at our Huddersfield or London Open Days then you can see these in action.
For more door entry info, have a look at the door entry section on our website.
We will have this demo kit set up at all times in our Huddersfield afterwards so if you are in the area pop in and have a look. Our plan is to have as much of our product range as possible on display and working so people can see what it does.
Oh and the brickwork image on the backgrounds of the stands is a genuine Savile Mill (the ProVu office) wall stone photo! No Google Image Search used here....

29/02: 6am start for Raspberry Pi
So, 6am this morning. The ProVu techies were up trying to get their hand's on a RasperryPI.
This is a new mini computer which runs Linux. They are cheap at $35. We all really excited about the launch. We all have ideas of things we want to build with the device. The educational aspect that kids can have a computer cheap enough to just play with is fantastic.
This morning, the announcement was that they had decide to use RS and Farnell for distribution. These are both huge companies. Farnell's turnover is £990 million.
We have an account with Farnell, so thought buying would be easy.
Unfortunately, I slept in until 6.03 by which time the websites of the both distributors had gone offline. Only now at 11:59 has the Farnell website been up enough to place a pre-order for the next batch.
It is all good.

21/02: Yealink Handset Training Day
Last week, ProVu ran a Yealink handset training course down at the University College London (UCL). Roy from Yealink UK was also present to oversee the course and answer the commercial stuff.

The course is designed to cover the range of Yealink products and give a better technical understanding of the products. Attendees should be able to configure the Yealink phones and perform simple diagnostics to trace problems.
A wide range of topics was covered: ranging from the very basics of setting up a Yealink phone to configuring OpenVPN and discussing Yealink security features, amongst other things.
Here is a picture of me demonstrating the Yealink video phone making a video call with a Protalk Door Entry unit:

There was a Yealink goody-bag for people to take away at the end of the day which included a Yealink cup for you to SIP from.
