Electronic Alarms and Home Security Devices - Wired zone problem with Ademco Lynx

Hi all, this is my first message in this forum :) and y posting it from Spain.
I purchased a Ademco Lynx 3 years ago and I installed it myself, and the alarm works fine with basic configuration and wireless sensors.
The problem is with zone 01, the wired zone, which dont works fine. I am trying to conect to it a infrared beam, and when I configure it with *56 - A01 - B03... (as perimeter) EVER says that the 01 Zone is fault, including when have not anything conected to it.
The infrared beam works fine, getting a contact normally open, and when the beam is interrupted, the contact is closed. I had connected the two wires contact to 5 & 6 pins from Lynx, but its the same, the zone its 01 ever fault.

Anybody knows how I must connect and/or configured the wired zone of a Ademco Lynx?

Thanks in advance.

Did you put a 2000 ohm resistor in the loop? The zone will not close unless you do so.

Yes I'd put a 2k resistor connected to 5 & 6 terminals of lynx, but the failure of zone 01 continues.
I had check the resistance with a multimeter and it measures 1k98, I suppose that it is acceptable.

Ok, reading your description carefully, you say you are using normally open contacts on your motion and they close on alarm. In that configuration, your resistor should be across the open circuit, either at the terminals on the motion detector(preferably), or at the terminals on the panel.

Have you tried simply putting just the resistor on the zone input terminals? If the zone closes, then the problem may be in how you are connecting the motion.

Most security contacts are set up to be normally closed and open on activation. The normally open configuration does work, but is a little more fussy about proper wiring procedures.

I have connected the 2k resistor directly to the terminals 6 & 7 (without wires) and set to the zone type 3 (perimeter).
When I try to put the lynx to parcial or total mode, the zone 01 show 'fault' and the alarm can not be operative.

May be a bad configuration of wired zone 01 instead of a bad connection?

Hmmm, your configuration information is pretty standard. If the zone isn't closing with just the resistor directly connected, then something is definitely odd.

When you put the resistor on, try entering the code + off (1), as if you were clearing a tamper alarm.

Check your *56 zone settings carefully, prehaps there's something you _thought_ you did, but did something different instead.

I dont know what is the + off code... :confused:

I set the zone 01 by the next way:
- installer code [20]
- *56 [A01]
- * [B00]
- 03 (for set perimeter zone type)
- * [C00]
- * [IC] (voice descriptor)
- 0 (and go to next zone A02)
- 00
- *99

Ademco panels do not automatically clear zone tampers. You have to enter a user code as if you are disarming the alarm ([code] + 0ff(1)).

By your description, you are programming the zone correctly, and there aren't any hidden settings that affect the hardwired zone, so it may be possible that your zone input has somehow been damaged. This is a _very_ simple system. There just aren't very many variables to check.
