738rBCDSustain ModeWhen removed, jumper B selects Sustain mode. This mode improvesthe ability of the 738r to discriminate between alarm eventsand non-alarm shocks (for example bird strikes or heavy backgroundnoise from busy roads or nearby railways).Calibration ModeFit jumper C in order to adjust the sensitivity or confi rm correctoperation. Remove jumper C to put the 738r into normal operation.Note that the 738r can only enter calibration mode when the lidtamper switch is open. (See “To Commission the 738r” below.)DiscreteFit jumper D to disable the Activity LED. Remove jumper D to enablethe Activity LED.Note: When delivered from the factory the jumpers are fi tted as follows: A: Removed(high sensitivity), B: Fitted (no sustain), C: Removed (normal operation), D:Removed (Activity LED enabled).Example Jumper SettingsReduced Sensitivity (see Fig 5). Use on: hardwood or metal window anddoor frames, or on masonry walls.Normal (see Fig 6). Use on: softwood or plastic window and door frames,where there is excess paint, a long distance from glass, or around largeglass windows. Note that this is the default setting when the 738r is deliveredfrom the factory.Improved Discrimination (see Fig 7). Use in installations with high backgroundnoise, for example near to busy roads or railway lines. If the shocksensor is not triggered then remove jumper A to select High Sensitivity. Recalibrate.Note: In the above examples, if the shock sensor is not triggered turn pot VR1 clockwiseto make more sensitive and re-calibrate.To commission the 738r:1. Fit jumper C and A to put the 738r into calibration mode at low sensitivity(see Fig 8).Note: If the battery is low then the Calibration LED fl ashes continuously. Fit a newbattery.2. Turn VR1 fully anti-clockwise. The 738r is now at its lowest sensitivity.3. Strike the extremities of the area you wish the 738r to guard. Use ablunt, hard-surfaced tool, for example a screw driver handle.Issue 1 5 of 6
