Yes most modern panels would be fine. Texecom Premier would be a pretty straight forward swap with them having compatibility with any keypad zones or EOL values. If you are getting somebody in to do it, I would let them spec which controls they support tho.

Logic 4 is likely to be 4 core era, possibly has a mechanical bell.

It's all easy if you know. 999 seconds =~ 16 minutes

You have set the Part Set Bell delay to 16 minutes like above.

Would need a Fire Risk Assessment done as part of the building work.

I don't see why public being there would make it mandatory, I can't recall that as a statement in regulations. "All commercial premises must have appropriate fire detection" that doesn't necessarily mean it's mandatory to have a fire alarm system installed.

You'd be using the comms output instead of the bell trig. I still believe Part Set Bell Delay or a Custom Output are the best two options.

That is another way but would require a little more setup over what I posted in post2 you would need adjust pulse timers then. Also have the issue of the bell not triggering on a tamper if you use "intruder".

Toggle switch like that is far from ideal. If it fails, you forget to switch it or it is found in a break in, your alarm is useless. The design behind a self activating bell is that everything is contained within it and only controlled by the panel so they are harder to defeat in a break in. I would suggest a small part set bell delay is the most appropriate.

Wind up merchants at it again.... I don't believe the do but they are in the unit round the corner.

That's not an out of the box option on a Premier. It's not something that you would normally do. You would need to use custom outputs to do custom things. Something like have a stage for Bell SAB and a Inverted stage for Part armed. Alternatively if it's concern for waking the neighbours in the night you can set the part set bell delay timer to whatever time you feel.

Considering the hype around the stuff for the last few years, I have never seen a system in the wild. Or know of any companies fitting the controls as standard.

It's likely you need to set zone 1 as entry and remove the default guard on part set like H says above.

Any 16 Ohm Loudspeaker like a CQR Alto for example.

Speaker is built in located under the circuit board but it's possible it's not working.

You have to set the zone type as Double Pole/EOL and you need to wire it correctly, that being using the outer terminals of the four in the keypad and your 4k7 and 2k2 wired in the contact as per the instructions in the manual. >65k means open circuit aka tampered.

On the topic of £10 profit. This is worth a watch, even if your employed or a customer similar things apply. There are things a lot of people don't consider from the other POV, like how much it costs to send you as an employed engineer to a job in the first place. Or how much time has gone into that job before you rock up in your van. Similar considerations from a customers POV, if your looking at a system on price alone then consider how much of that price is related to kit quality. Businesses can only survive by making a profit after paying the wages.

Only fitted one a good while ago, Had to fit stainless bell to suit the job. I believe they are pretty decent. I can only imagine the other wire would be a battery link (maybe answers your OP, why you have no hold off triggering) but maybe someone that has fitted one more recently can help.

I wouldn't say temporary fix, more permanent damage.

Good luck if you can survive and build a business doing all jobs with a 20% discount. Something will catch up with you eventually.

Alarms if fitted correctly are designed to time out to limit noise pollution. There is no guarantee that it would stop tho. I have known systems to keep ringing out in certain fault conditions.

20 minutes if BS, 15 minutes if EN

As you can see people don't agree. It's all down to if you see it as a box pushing game or a service industry IMO. You can push as many shiny new boxes as you want but customers want a good service, it's the peace of mind and trust in your system and installer people should focus on.

I still say a good, well maintained, fit for purpose system wouldn't need ripping out. People are too quick to add to the E-waste pile IMO. It's easy to say you swap your car or phone more regularly than your alarm but most of this consumer stuff is designed with a short lifespan in mind and you are trapped to a platform. A lot of my electronic equipment is 10 years old but its well looked after, I'd only plan to replace it when it's unserviceable.

Doesn't mean the standby battery is large enough tho. Depends if that was checked when it was fitted.
