On-Board Dual Stage Shock Sensor; Zones - Directed Electronics 3901V Installation Manual

On-board dual stage shock sensor

Less Sensitive
More Sensitive
There is a dual-stage shock sensor inside the control module. Adjustments are made via the rotary control
as indicated above. Since the shock sensor does not work well when mounted firmly to metal, we recom-
mend against screwing down the control module. The full trigger of the on-board shock sensor reports
zone 2. See Table of Zones.
NOTE: When adjusting the sensor, it must be in the same mounting location that it will be after the
install is completed. Adjusting the sensor and than relocating the module requires readjustment.
