Honeywell Gd-48

Hi all,

 

I fitted the above about 6 months ago, the following is the setup:

 

GD-48

3x MK8 Keypad's 

1x External powered RIO

Handful of PIR's

Handful of G3 door mags

Elmdene bell box

Ethernet Module for Self Mon

 

All has been working excellently up until today, the alarm put out a tamper so all 3 keypads were beeping constantly, upon me trying to input a user code or the manager code not 1 of the keypads would accept any key presses.

 

While this is ongoing randomly on different keypads the static white LED would flash rapidly, also the beeping would stop altogether then start again.

 

I eventually managed to get into the system using the manager code to see 18 alarms of "keys missing" is this the keypads going offline on the RS485 bus?

 

It now sits with all groups disarmed and in engineer mode but again no keypad is accepting any key presses.

 

The only thing that changed in the environment was that my BB router has failed so the system cannot contact the selfmon arc.

 

Anyone got any ideas please?

 

Thanks in advance.

To follow this up, the keypads have now come back and they can be accessed.

 

In the logs I got the following:

 

-MISSING RIO

-MISSING COM4

-MISSING KEY

 

These are repeated with the relevant address for the RIO or keypad addresses.

 

I know it's a hot day today but no keypad is in direct sunlight and the controller is not in a hot place.

 

Anyone have any experiences of this?

 

Thanks again.

Hi Nick, this is Stuart from www.SelfMon.co.uk

 

This sounds like a bus issue and unfortunately can be caused by any of the devices on the bus - including the panel itself.

 

I'd like to go through some diagnosis steps with you just to see if we can narrow the root cause. Please contact me at my selfmon admin email address.

 

Stuart.

Yes as above looks like a bus or device issue. Assuming you have checked and tested the cabling then just remove one device at a time. You could also split the busses as iirc the 96 has 2 busses

Cheers Stuart I will email you.

 

As for changing the bus I cannot as it's the GD-48
