1.Fix the base with two tapping screws,and then connect loop to terminals(polarity-insensitive).After thebase is fixed firmly,rotate the bottom of detector and base clockwise,and then the detector will be fitted tothe base.
2.Wiring instructions:RVS twisted pair with cross-sectional area≥1.0mm2 should be selected for the secondbus of the detector,which should be laid through metal pipe or flame retardant pipe.The length of theconnecting wire should be limited to the single bus resistance≤20Q,otherwise the wire diameter should beincreased.
▪non-polarized two bus,ultra-low power consumption,no need to add DC24V power supply
▪passive outputvv input and output have isolating loop to effectively filter out external interference
| Rated operating voltage | Loop:24V(14V~28V); |
| Operating current | Monitoring current: ≤ 0.2mA start current: ≤ 0.5mA |
| Operating Environment | Temperature:-10℃~+55℃; Relative Humidity:≤95% non-condensing |
| Input supervisory external loop | Open circuit occurs when normally open terminal supervising externalloop (short circuit is an action signal), the module will send a fault signalto the control panel. |
