D. OTHER COMPONENTS
All of the remaining electronic components are secured to a printed circuit board and are not
readily field replaceable. If further repair is needed, it is required that the entire instrument
be returned to the factory for rework, to maintain the Intrinsic Safety of instrument.
E. REPAIR
For repair of other components, it is recommended that you call your local distributor or
MST @ 1-800-542-6646 or 1-888-MOD-SAFE.
VI. ACCESSORIES
A. ALARM REPEATER - P/N 80444
This accessory is a piezoelectric audible alarm (85 dB (A) at 1 Ft.) with a 6 Ft. shielded
cable that plugs into the REM of the instrument. It is CSA APPROVED INTRINSICALLY
SAFE for use in Class 1, Division I, Groups A,B,C&D when instrument uses two “9V”
transistor type alkaline batteries for the power source.
WARNING:
THE INTRINSIC SAFETY OF THE INSTRUMENT IS VOIDED WHEN THE
FOLLOWING ACCESSORIES ARE USED.
B. CONTINUOUS OPERATION ADAPTER (115 VAC) - P/N 80247
This accessory will supply operating power to the instrument as long as it is plugged into
active 115V AC outlet, whether or not batteries are installed. The Adapter will convert
the 115 VAC to 7.5 VDC, 650 mA.
1. Plug continuous operation adapter into an active, fused (1 amp) 115 V 50/60Hz
outlet. NOTE: To prevent unnecessary electrical interference, the outlet should
be on a dedicated circuit free of any intermittent heavy loadings such as pumps,
compressors or heaters.
2. Plug adapter cord connector into socket on the lower right-hand side of the
instrument.
3. Adapter will power the instrument as long as the 115 VAC source remains active.
4. Since the adapter voltage is slightly higher than that of the internal batteries, the
adapter will supply the power. Blocking diodes protect the internal interface.
