TOMCAT Posted March 16, 2007 Share Posted March 16, 2007 Hi I have just fitted a Gardtec 593 panel which is working great,trouble is I want to add a RFID reader upstairs and use this to enable/disable the alarm at night. The RFID reader has a relay output but when connected to the Gardtec it does not enable/disable the panel. I have programmed a zone as biased keyswitch (reader only gives a short 1-3 sec break or make contact) but cant get it to work.Question is,do I need to put a certain resistance across the relay output so that the panel recognises it as a keyswitch or is there some programming trick that needs to be done. Thanks in advance for any help. Link to comment Share on other sites More sharing options...
Richard Huison Posted March 16, 2007 Share Posted March 16, 2007 Can you tell me what reader it is, as this may help me solve your problem. I would say a resistor wont solve the problem. Also you need to find out if your input requires a toggle or pulse to set the system. Dont quote me on this but i think the Gartec can accept a reader as long as it kicks out a 26 bit weigand format. Let me know. Richard www.accesscontrol.ie richard.huison@accesscontrol.ie ACT "Where performance counts" "Is your Access Control system Vista Ready?"

TOMCAT Posted March 16, 2007 Author Share Posted March 16, 2007 Hi Richard Gardtec 593 can be set for a normal keyswitch (i.e turn key to set state to open or closed then remove key) or what it calls a biased key (where you toggle the connection from closed to open or vice versa briefly),I,m just not sure if there is more to a biased keyswitch than just a toggle switch.I am not trying to interface the RFID via radio merely to use it as a keyswitch albeit controlled by a RFID tag rather than a plain keyswitch (no real reason for this apart from the fact I have a RFID pad to hand) .Thanks for the reply though(btw I dont know what a weigand format is but it sounds a bit complex for my needs ) Link to comment Share on other sites More sharing options...

You will need a reader with a matching token (Fob, card etc) and a suitable interface for the reader. As Angus says, Gardtec do a keypad with reader. Probably the simplest option.

TOMCAT Posted March 16, 2007 Author Share Posted March 16, 2007 I think I have not explained myself properly,I am using the RFID reader simply as a keyswitch,forget the fact it is an RFID device,I simply want to use it as a keyswitch and interface it to the Gardtec panel.It activates a relay when I place a RFID tag beside it and the output of this relay is wired to the panel but I cant get it to work. So I guess the question I should have asked is if you are wiring a biased keyswitch to a Gardtec 593 panel then is the keyswitch anything special or is it just a normal key with switch contacts.

Guest anguscanplay Posted March 17, 2007 Share Posted March 17, 2007 if the relay works youve got something wrong at the control unit this panel isnt really aimed at the diy market why re invent the wheel when you could use original equipment Link to comment Share on other sites More sharing options...

Service Engineer Posted March 17, 2007 Share Posted March 17, 2007 Have you tried to make this work without the RFID.? Is the relay N/O, If so have you wired the zone as you would a N/O device.? The keyswitch only uses 2 cores of cable, make sure it's working by just touching the two wires together first. BTW: I'm a bit rusty on Gardtech's, haven't seen one for a few years now. ........................................................

Guest anguscanplay Posted March 17, 2007 Share Posted March 17, 2007 once you have proved the relay you will have to go into programming and set that up too Link to comment Share on other sites More sharing options...
