Introduction  
1.1 General Description  
Remote Alarm and Alarm/Meter (948A-40 & 948A-50)  
The 948A-50 Remote Alarm/Meter continuously indicates the level of radiation at the detector site and provides a  
visual and audible indication of a high radiation level on an analog meter, light, and Sonalert. The meter of the  
Remote Alarm/Meter is an analog meter scale that indicates in the range of 0.1 to 107 mR/h. The light and Sonalert are  
actuated when the radiation level exceeds the high alarm set point of the Universal Digital Ratemeter. Both models  
have a momentary pushbutton to silence the Sonalert. The 948A-40 and 948A-50 enclosures are Steel. The 948A-40 is  
identical with the exception that it has no analog meter. Refer to Appendix A for drawings.

Section 2  
Installation  
2.1 Installation  
CAUTION  
Ensure all power is removed prior to installing the 948A-  
40 or 948A-50 Remote Alarm, Alarm/Meter.  
Installation of the 948A-50 Remote Alarm/Meter consists of finding a suitable location for mounting, such as a wall or  
post, and providing an electrical interface. Both the 948A-40 and 948A-50 Remote Alarm, Remote Alarm/Meter can be  
mounted up to 1500 feet from the detector and UDR.  
There are two possible wiring configurations (reference loop diagram 945-3 or 945A-3 in Appendix A). In the first  
configuration, terminal block TB2 is used as a junction for the VICTOREEN communications loop between the  
preamplifier and ratemeter. The signals that drive the meter, Sonalert, and light originate at the preamplifier and are  
connected to TB1.  
In the second configuration, the VICTOREEN communications loop wiring runs directly from the ratemeter to the  
preamplifier, eliminating the need for TB2. The signals that drive the meter, Sonalert, and light are connected to TB1  
as in the previous case.  
Use the following procedure to install the remote alarm, alarm/meter:  
1. Select a suitable location for the 948A-40 Remote Alarm or the 948A-50 Remote Alarm/Meter.  
a. The length of the cable must not exceed 1500 feet (450 meters).  
b. The access holes for the cables are located in the bottom panel of the remote alarm, alarm/meter  
housing.  
2. Mount the remote alarm, remote alarm/meter to the supporting structure. Refer to drawing GEL948A-50,  
located in Appendix A, for mounting dimensions.  
3. Route the cable (P/Number 50-150 or equivalent) between the rate meter and the remote alarm, remote  
alarm/meter or between the rate meter and preamplifier (refer to loop diagram 945-3 or 945A-3 in Appendix  
A).  
NOTE  
When using the first configuration, connect the wires of  
the cable to the terminal block located inside the remote  
alarm, remote alarm/meter housing.  
4. Verify that all electrical connections are correct and secure.  
5. This concludes the installation procedure for the 948A-40 Remote Alarm and the 948A-50 Remote  
Alarm/Meter.

Section 3  
Operation  
3.1 Operation  
Since the operation and theory for the 948A-40 is identical to the 948A-50 with the exception that the 948A-40 has  
no meter, only the 948A-50 will be discussed.  
Once installation has been completed, operation of the VICTOREEN 948A-50 Remote Alarm/Meter is automatic and  
does not require operator attention.  
The analog meter continuously indicates the level of radioactivity measured at the detector site from 0.1 to 107 mR/h.  
The light and Sonalert are actuated only when the radiation level at the detector site exceeds the high alarm set point  
established at the ratemeter.  
When an alarm condition occurs, the 12 VDC output from the detector preamplifier energizes causing the Sonalert  
audible alarm to sound and the alarm lamp to illuminate STEADY ON.  
The audible alarm can be silenced by pressing the "silence" pushbutton on the front panel, causing the Sonalert to  
de-activate and the light to remain illuminated. An alarm condition cannot be canceled locally. The Sonalert and light  
are automatically de-actuated when the alarm is acknowledged from the digital ratementer.  
3.2 Theory of Operation  
This section contains the theory of operation for the 948A-50.  
During a high alarm condition, the light will illuminate and the Sonalert will sound. A silence button, located on the  
front of the local/alarm meter, is provided to enable the operator to silence the Sonalert.  
When a high alarm condition occurs, a 12 VDC input is introduced to the alarm circuit. This signal will cause the light  
to illuminate. This 12 VDC input is also applied, via a normally closed contact of relay K1, to the Sonalert, energizing it.  
To turn off the Sonalert, the silence pushbutton on the front panel may be depressed. This will cause the normally  
closed contacts of relay K1 to open, which in turn de-energizes the Sonalert.  
When the system returns to a normal operating level of radiation, the remote alarm/meter will return the relay to the  
normal operating position.  
When the alarm is powered from the preamplifier 12 VDC output, acknowledging the alarm from the digital  
ratementer, will turn the 12 VDC input off, turning the audible alarm and the visual alarm off.

Maintenance, Calibration,  
and Troubleshooting  
4.1 Maintenance  
The 948A-40 Remote Alarm and 948A-50 Remote Alarm/Meter require no routine maintenance other than periodic  
calibration for the 948A-50. Refer to calibration for further information.  
4.2 Calibration  
The 948A-50 requires calibration before it is initially placed into service. In addition, it should be recalibrated at regular  
intervals during routine service. The length of time between calibration intervals should be determined by the  
customer. Use the following procedure to perform the calibration:  
1. Using radios, field telephones, or other suitable communication devices, establish communications between a  
technician at the ratemeter location and another at the remote alarm/meter location.  
2. To gain access to the meter adjustment potentiometer, open the front panel of the remote alarm/meter. The  
potentiometer is mounted on the rear of the panel meter.  
3. Adjust the potentiometer until the reading shown on the panel meter agrees with the reading shown on the  
ratemeter within ±5%.  
4. This concludes the calibration procedure for the 948A-50 Remote Alarm/Meter.  
4.3 Troubleshooting  
WARNING  
Extreme care must be used when troubleshooting a  
system that has power applied. All standard  
troubleshooting precautions apply.  
WARNING  
Once a problem has been located, remove all power  
before continuing with the repair.  
CAUTION  
Personnel performing the following procedure must be  
familiar with the operation of the system and the  
location of each piece of equipment used.
