2.1 Installation
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).
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.
