Introduction

The 46RX family of eight-channel receivers can be used either as stand
alone units, or the radio interface for a wired alarm panel.

The 46RX family comprises three variants:

• The 4618-50 which requires an external 12V power supply.

• The mains powered 4618-60.

• The 4619-50 expansion unit.
Each of the 46RX family provide three common outputs. By adding the

optional 8-Channel Relay Card 4618EUR-55 each variant can also provide
eight additional output channels.

By connecting up to three expansion units an installation can be made to
cover 32 separate, programmable channels.

The 46RX family works with the 4600 range of Scantronic transmitters.
Any one of a range of aerials can be fitted to the 4618-50/60 receivers.
Each member of the 46RX family provides space for a backup battery. A

suitable battery is a sealed 1.2 Ah 12V lead acid type.

TECHNICAL DESCRIPTION

Physical Layout

The 46RX family are wall mounted units housed in a polycarbonate box
made to BS4734 requirements. Figure 1 shows the general layout of the
main components.

Technical Description 4618

The receiver and decoder circuits are on the main circuit card mounted
securely within the lid. The body of the box contains space for:

• The power supply (fitted in the 4618-60 only)

• A backup battery (not supplied)

• The 4618EUR-55, an optional 8-channel relay output card.
There differences between the three variants of the 46RX are:

• The 4618-50 power supply enclosure is empty, and there is no mains

cable terminator.

• The 4618-60 is fitted with a mains power supply, and mains cable

terminator and fuse.

• The 4619-50 has no mains power supply, and no receiver on the main

circuit board.

the connectors and controls.

4618 Inputs

Inputs
Radio

The 4618-50 and 4618-60 contain a standard Scantronic radio receiver which
connects to a BNC aerial socket mounted on top of the case.

Each detector sends information to the receiver using an attached radio
transmitter. The transmitter relays the information in the form of radio data
packets, using an FM signal. The signal contains a code identifying the
transmitter and information on the state of the detector. Every receiver within
range picks up the transmitter’s information, but reacts only to those transmit­ters it has been programmed to notice.

Mode Switches

The Mode Switches are the controls that tell the system which transmitters to
notice, and what to do with the information received. Figure 2 shows the
location of the Mode Switches on the main circuit card in the lid.

Tamper

The 46RX family contain an internally mounted tamper switch to detect
opening of the case lid (see Figure 2). The switch gives a normally closed
loop isolated from any circuits on the main circuit card. This output can be
used as required. The switch contact opens when the lid opens.

Jamming

The 46RX family can detect radio jamming if Mode Switch 3 is ON. The
cause of jamming may be interference from nearby equipment, or the re­ceiver detecting the radio carrier continuously. See “Fault Finding” for more
information.

Reset

The 46RX family have a Reset button on the front control panel. Pressing
Reset clears all the output channels and LEDs.

If you have an expanded system with two or more members of the 46RX
family connected together, then:

• Pressing Reset on the 4618-50/60 will reset only the 4618-50/60, and
not any attached 4619-50s.

• Pressing Reset on an attached 4619-50 will reset that unit, but not any
of the other units connected to it.

Each member of the 46RX family also has a connector for an external reset
signal (see Figure 2). By applying 12VDC to the positive terminal of the reset
connector and then removing it you can reset a system of connected 46RX
family units.

Outputs
Front Panel

Each member of the 46RX family uses the display panel shown in Figure 3.

The vertical column of eight LEDs indicates the status of each channel
output.

The symbols on the right of the panel have the following meanings:

A Common Output A
B Common Output B

Common Output Relays

Members of the 46RX family provide three output relays: Common Output
Channel A, Common Output Channel B and Low Transmitter Battery. Figure
2 shows their position and connectors.

The Normally Open, Normally Closed and Common Terminals of the relays
provide voltage free change over contacts.

The 46RX family use the Common Output Channel relays (and LEDs) to
report the status of transmitters. See Programming for more information.

The 46RX family use the Low Transmitter Battery relay to report that a
transmitter's battery is failing. See “Fault Finding” for more information.
