INTRINSICALLY SAFE TYPE APPROVAL
The IC-U8S1 conforms to intrinsically safe ratings of the FMRC (Factory Mutual Research Corporation). Depending on intrinsically safe type classifications, 2 types, the IC-U8S1 and IC-U8S2, are available.
- IC-U8S1:
- Intrinsically safe: Class I, II, III, Division 1, Groups C, D, E, F, G
- Nonincentive: Class I, Division 2, Groups A, B, C, D
- Max. temperature range: T4A
- Connected battery pack: CM-79 only
IC-U8S1 Options
WARNING: The IC-U8S1 DOES NOT meet the required intrinsically safe requirements when the optional UT-46 DTMF ENCODER UNIT is used.
- CM-79 BATTERY PACK: Voltage: 7.2 V; Capacity: 600 mAh. Intrinsically safe type. Same as supplied with the IC-U8S1.
- BM-71U/E AC BATTERY CHARGER: Desktop type. Rapidly charges the CM-79 within approx. 60 minutes.
- FA-450TA FLEXIBLE ANTENNA: Long-type flexible antenna. Ensures you longer distance communications.
- UT-46 DTMF ENCODER UNIT: Provides repeater control and autopatch ope
