Pendant alarms recommendations?

[TeenDivided]

Does anyone have positive recommendations for pendant alarm companies (or those to avoid).

2 elderly parents, both hard of hearing, need one each. Something they can speak into directly. Would prefer wrist ones if possible.

Fall sensors - do they work in practice?
Is 'outside the home' worth it over and above a mobile with an emergency button?

Following with interest. An IWatch was also suggested as it has a fall sensor and heart rate monitor ?

MY MIL had a council one . My dad has a private one.
The advantage of the council one is that if they press it a carer will come.
The one my dad has phones me or my brother.

Going round in circles, not least because parents aren't keen on a key safe.

Choosing between Taking Care Anywhere and Safe Sure Go.

Personally I think either would be fine, and risk of not having access when needed outweighs risk of keysafe being broken into if put somewhere obscure.

Mum had a local authority one which we paid for. If she pressed it they would call us first and if there was no reply or we weren't near they would call either a carer or an ambulance depending on the circumstances . We did get a key safe which was absolutely essential and worked brilliantly .
My mum had dementia and it was just getting to the stage where it was becoming dangerous for her to live on her own when she had a stroke. Overnight she became doubly incontinent and unable to weight bare so was unable to stand/walk etc . She then had to go into a care home as she needed 24 hour care.

Following the thread with interest. Does anyone have experience of similar for elderly people with severe hearing impairment (ie can't hear over the phone). The person I have in mind is of sound mind and limb, and could talk into a phone but wouldn't hear the responses. Problem with most of these systems (that I've found anyway) is an alarm is met with a voice message from the base unit to assess the situation. My person couldn't hear that - so the help team would presumably only be able to call me (I live in a different town so couldn't assess) or an ambulance. Which might be unecessary. Ideally the helpdesk would communicate by text or (better) email to resolve. Has anyone come across anything like that?

We have 4 elderly relatives at the moment living in 3 different homes.

All have alarms and 3 of them are deaf, so the two living alone and one of the couple.

Two of them have old iPhones with compatible hearing aids, through the NHS.

My "D"M can't won't even try to use her iPhone so she had a C landline bought through the RNID.

If you can arrange an Occupational Therapy referral they might be able to help with this.

Have they got a fire alarm that goes under their pillow too?

Thank you very much @PolaroidPrincess that's very helpful. Actually DM seems to be past the point of learning smartphones (or indeed non-smart phones). However will check out if there's away to connect hearing aids to VOIP landlines.

And as it happens the an OT visit scheduled for another matter (bath access) so will see if there can be crossover.

Just to be clear DMs hearing aid don't connect to her landline but the landline phone is so, so loud she can actually hear it.
