I want to install a Texecom intruder alarm system into an apartment to replace a very basic RISCO panel. This has four wired RISCO PIR detectors and single entrance door with contact switch. It has one remote keypad

My requirements are to keep the exiting PIRs and contact switch. Replace the keypad and have an auto dialler connected to analogue telephone.

However I would like the option to send additional details alerts (stating what activated the alarm) via text message or email, and have the ability to view the event log via a PC as well as program and interrogate the control panel over TCP/IP. I don't know the Texecom products very well but it looks like I would need a panel that is compatible with the Premier Elite ComIP communicator.

Further more I would like to
(1) arm/disarm the alarm via Paxton Net2 access control system
(2) send a output signal to the alarm input on AXIS IP camera when the intruder alarm is activated
(3) be able to receive input from a smoke and/or CO detecor

Can you recommend a Texecom alarm panel?

Any of the premiers could do that but u will need a few modules. Have a look at the Honeywell flex this will do as you need and has app support. I wouldn't recommend sms alerts unless using a gsm module.

I could not identify this product in your online catalogue. Please confirm the specific Honeywell system you refer to.
