GSM auto-dialler query

[Axotyl]

There are several GSM speech and text auto-diallers available. One model is the Menvier SD3, with 8 Trigger inputs and 4 outputs plus 10 alert contacts.

 

Can any user familiar with this device inform me whether one can configure a Trigger input (say PIR) to switch on an alarm (or siren, or light etc.) in addition to sending an alert?

 

Specs are here: https://bit.ly/3lUH5bJ

 

A similar auto-dialler is here: https://bit.ly/3iw1vWa with less inputs.

 

We're only interested in GSM devices, as landline isn't available. We've spent a month researching auto-diallers, and have been continually told by installers that they have to have utilise a copper landline, which these devices don't.

Well the PIR has alarm contacts so you could use them maybe with a relay just to trigger the input on any autodialer , there many cheaper devices which will do the just b for you on eBay 

 

For example 

 

https://www.ebay.co.uk/itm/Alarm-Installer-Auto-Dialler-with-Controllable-Relay-/233783581818?mkcid=16&mkevt=1&_trksid=p2349624.m46890.l49286&mkrid=710-127635-2958-0

They have different versions , but I would recommend a cheap monthly contract SIM , you will kill your credit quick otherwise

I would always connect your detectors to a control panel then the panel to the dialler. Yes gsm diallers do exist but alarm pros would use a monitored path device not a dialler

[Axotyl]

Thanks, al-yeti - I looked at the eBay device, but it doesn't have as many programmable features as either of the two auto-diallers in the original post, and I guess the cost reflects that.

 

James.wilson - I understand that using GSM is unlikely to be as reliable as landlines, but my thinking was that the auto-dialler in the original post would have one SIM card, and there would be a separate card in the Huawei router which would support additional CCTV (plus a weather station), and provide a back-up warning to an intruder. If the cards were with separate providers, then it's unlikely both would fail at the same time, so fail-safe?

 

Both the auto-diallers above have several additional features, and I'm not clear why they would need a separate control panel.

 

I'm just an amateur, and I realise that I'm going to need an installer who's familiar with GSM auto-diallers, to go through the options with us. The property is situated in the BN7 postcode, so would appreciate a professional making contact ( two warehouse/hangars, one needing CCTV/alarm, the other external CCTV monitoring).

It's not the transmission path it's the polling, monitoring has polling.

You can't test if a service works without sending something over it, if you only send stuff when it's urgent you don't know if it will fail.

[Axotyl]

Thanks, 6Wheel.  Both devices quoted above can be programmed to send test alerts routinely, at varying intervals, and same with CCTV we've been looking at.

[sixwheeledbeast]

test alerts != polling

[james.wilson]

Yes proper monitoring will be polled depending on the grade etc

Anywhere from every few seconds to once a day. 

I would always use a panel to connect your detectors to, you need something to arm disarm, power supply battery monitoring logs etc etc

what plonkers have you been talking too ?

 

phone lines are finished for alarm signaling.... you need to put your hand in your pocket & buy a proper alarm from a proper alarm company with proper signaling
