IMPORTANT !!!
Linear radio controls provide a reliable communications link and fi ll an important need in portable
wireless signalling. However, there are some limitations which must be observed.
• For U.S. installations only: The radios are required to comply with FCC Rules and Regulations
as Part 15 devices. As such, they have limited transmitter power and therefore limited range.
• A receiver cannot respond to more than one transmitted signal at a time and may be blocked
by radio signals that occur on or near their operating frequencies, regardless of code settings.
• Changes or modifi cations to the device may void FCC compliance.
• Infrequently used radio links should be tested regularly to protect against undetected
interference or fault.
• A general knowledge of radio and its vagaries should be gained prior to acting as a wholesale
distributor or dealer, and these facts should be communicated to the ultimate users.

PRINTER’S INSTRUCTIONS:
INSTR,INSTL,AL-1 - LINEAR P/N: 218387 B - INK: BLACK - MATERIAL: 20 LB. MEAD BOND - SIZE: 11.000” X 8.500” - SCALE: 1-1
The Model AL-1 is a wireless personal alert receiver designed for use with existing
nurse call annunciation systems. In a typical installation, the receiver is used in the
place of, or in conjunction with, a standard pull cord to activate a corridor light, bed
light, room light, and any audible devices to indicate the need for assistance. Up to 32
wireless transmitters can be programmed to activate each receiver.
Three indicators on the front of the receiver display the system status. The green
POWER indicator lights when power for the receiver is present. The yellow SERVICE
indicator lights if a transmitter has sent a low battery signal. The red ALERT indicator
lights when a transmitter has been triggered, showing that the receiver’s outputs have
been activated.
Pressing the RESET button on the top of the receiver for less than two seconds will
reset any transmitter low battery indications. Pressing the RESET button for more
than three seconds will clear the ALERT indication and reset the relay outputs if in
the latched mode.
The receiver contains four normally open 1-amp relay contacts that close when
activated. One relay provides an isolated output. The three other relays are isolated
when open and have a common return. The receiver relays can operate in “normal” or
“failsafe” mode. In normal mode, the relays will energize when the receiver is triggered.
In failsafe mode, the relays are energized continuously until the receiver is triggered.
Failsafe mode supervises the system by causing the outputs to activate if power is
removed from the receiver. Both modes provide normally open outputs.
Power for the receiver is supplied by a plug-in transformer. The receiver can be
mounted directly to a wall or to a single-gang electrical box with the hardware
supplied.
