Motion Sensor Problem - DSC 1550
After hard re-setting the system and entering a new master code, all is well with the system apart from the motion sensor operation. When there is motion detected, the "trouble" lite comes on the keypad, but the alarm does not go off. As soon as the motion stops, the system returns to normal. All other aspects of the system are working. Please help.

Does this happen when the system is armed?
If it happens when the system is disarmed it just may be the way your system reports that the motion sensor sees movement but does not trigger an alarm because it is disarmed.
Viewing Trouble Conditions
The PC1 500/PC1550continuously monitorsa number of possible troubleconditions.
If one of these trouble conditions occur, the keypad will beep twice every 10
seconds and the keypad "Trouble" indicator will light. Pressing any key on the
keypad will silence the sounder but the "Trouble" light will remain ON until the
trouble condition is cleared. If you cannot determine the cause of the trouble
condition, contact your installer for assistance.
To view type of trouble:
Press[*][2] to display the type of trouble. Azone light will come on to indicate which
type of trouble exists.
Press [#] to return to Ready.
ZONE LIGHT TYPE OF TROUBLE
1 ......................... Low battery.
2 ......................... Loss of AC power ("Trouble" light will come ON, but keypad buzzer will not sound).
3 ......................... Fuse open (BELL or AUX fuse).
4 .........................Fail to communicate with monitoring station.
5 ......................... Fire loop(s) trouble.
6 ......................... Loss of time on system clock.

It happens when the system is both armed and disarmed. There is no beeping from the keypad. When I press *2 the trouble lite flashes continually, but no zone lites illuminate.

If I had to guess; I'd say that you may have programmed the zone type for that zone incorrectly.
Zone 8, for example defaults to being a fire zone that expects a normally open circuit with an end of line resistor. Since the motion's relay contacts open with every activation, such a zone would show a trouble, and I don't think fire zone troubles latch on a PC1550.

Thanks for the reply.
A couple of things I don't understand. You mention zone 8, but I only have 6 zones on this system.
When I re- set the system all the zones returned to the previously programmed state. i.e.
Zone 6 - Motion Sensor.
However, the zone doesn't show a trouble. The trouble light only comes on when motion is detected.
When I press *2 the trouble lite flashes continually, but no zone lites illuminate.
As soon as the motion stops, the system returns to normal. All other aspects of the system are working.

That was actually a typo. What I meant to type was that zone 6 defaults to zone type 8, which is a fire zone.
If you used the hardware default on the system, but didn't reprogram the zones to match your current configuration, then the zones are setup wrong. You may have simply lucked out that the other 5 zones matched the default zone types. (1=delay; 2 & 3=instant; 4 & 5=interior)
What you are describing would match up perfectly with this, because every time the PIR detects motion, it breaks the circuit, triggering the fire zone supervision.

Thanks. That makes much more sense. The problem now is - how do I reprogramme the zones? I have the installers manual,but the re-set did not default the installers code. i.e. *8 1500 does not let me enter the programming mode. What do I do next?

To reset the Installer's code to 1500:
1. With power on, short default pins and type * 8 0000
2. Remove short from default pins and press 91 to remove the lockout.
3. Press 20, then 1500, then press # #.
Once you have done that you should be able to get into programming to correctly set your zones and do things like disable the dialer (which defaults to on).

Thanks again for the info. One last question (hopefully). Are the default pins you refer to, the same EEPROM RESET pins that I shorted out to reset the system in the first place?

Brilliant!!! What I actually did was swap zone 5 and 6 wires around in the control box. Everything is now working perfectly. Many thanks for your help - what a great site this is.
