Third, if AC voltage is present check the AC input fuse. Second, if the LED on the outside of the box is out check the AC input, if there is no AC voltage present you have found your problem. If all of the LEDs are out use a meter to check between F1 and F2 on the power distribution board if you see system voltage here then your fire alarm has disconnected the system. The LED should go on and the system should operate. If the LED is out disconnect the output using the associated slide switch correct the system short and then reconnect the output with slide switch.
#DOES FRONT SAM HAVE TO HAVE SCN CODING IF REPLACED 08 GL550 SERIES#
On the BPS series supplies over 1AMP each output if fused and the output LED will be on if the output is working. To correct this on the 1AMP supply, disconnect the load for 15 seconds, correct any possible system shorts and then reconnect the load. If it will not move, dismount it and clean and lubricate (or replace) the mounting hardware.įirst, look at the LED on the outside of the box if it is on then the supply is working and the problem is probably an open poly switch (fuse). You can check this by trying the move the strike by hand with the door open. The final possible cause is that the strike mounting hardware has somehow become frozen so that the strike has lost its movement ability towards and away from the magnet body. It can be corrected by either readjusting the hanging position of the door or readjusting the level of the strike (by turning the two strike mounting screws) so as to reduce the gap to the correct dimension. If the actual gap is significantly greater than this, you have found the problem.
Note that the gap is supposed to be 1/10 inch or the point at which the tops of the buttons just graze the magnet surface. This can happen, for example, when the lock is mounted at the top of the door and the door sags downwards which increases the gap. The second possible cause is that the gap between the magnet body and strike plate has widened to the point that the magnet can no longer pull the strike plate in. In some cases, this problem can be corrected by adjusting the door but re-mounting the unit properly is often required. You should see it "try" to move against the magnet body but note that the buttons are acting as stand-offs because they are not lining up with the holes.
Watch the strike closely as you very slowly close the door. You can normally visually detect such an alignment problem. A misalignment greater than 1/8 inch end to end or front to back will cause engagement failure. There are three potential causes that can produce a failure of the buttons to seat.įirst, the mounting alignment between the strike and the magnet body can be off so that the buttons don't line up with the conical machined holes in the T brackets. If the buttons do not seat, the lock will not hold. The SAM operates by pulling the strike plate against the magnet face when the door closes, seating the conical buttons on the strike into corresponding machined holes at either end of the magnet body. If everything checks out contact the factory. Meter between the face of the bar and the point were the antenna wire solders to the board you should see near zero resistance. Checking between red and black with a meter you should see system voltage.įourth, if the back up button works, you have tried adjusting the sensitivity and you have good voltage at the six pin connector check the antenna wire and make sure it is connected to the bar via the Phillips head mounting screw also check to make sure that the screw is not stripped.
Third, if the door does release when you press the back up release button and you have tried adjusting the sensitivity then you need to check the voltage for the bar at the six pin connector that connects the cable to the board. Second, if the door does release when you press the back up release button check the sensitivity adjustment potentiometer on the back of the board turning the POT clockwise will increase the sensitivity and the bar may begin to function. First, press the back up release on the back of the bar if the door does not release the there is a fault in the systems general wiring.
