KEYFOBS (KF-234 PG2)

Wireless PowerG 2-Way Keyfob

1. INTRODUCTION

KF-234 PG2 is a miniature
PowerG 4-button (6-function)
keyfob, designed for use with the
PowerMax10-G2.

Transmission is initiated by
pressing any one of the four
recessed pushbuttons. Upon
pressing a specific button, the KF­234 PG2 transmits a PowerG
message associated with the
button that was pressed and
identifiable by PowerMax10-G2
control panels.

Figure 1:

External View

A red LED lights during transmission. When an identified
command is received by the PowerMax10-G2 control
panel, it acknowledges the command. Upon
acknowledgement, the green LED lights and a happy beep
is heard to indicate successful completion of the command
or the red LED lights and a sad beep is heard to indicate
that the control panel cannot perform the command.

In addition, a battery report is transmitted with

the outgoing

message. PowerMax10-G2 control panels are designed to
identify this report and operate a corresponding output, if
required.

Each keyfob is supplied with a small key ring.

Operating power is obtained from an internal 3V Lithium
battery.

2. SPECIFICATIONS

Frequency Band (MHz): Europe: 433, 868, USA: 915

6.2 Cleaning

The keyfob may get dirty if touched with greasy fingers.
Clean it only with a soft cloth or sponge moistened lightly
with a mixture of water and mild detergent, and wipe it dry
immediately.

The use of abrasives of any kind is strictly forbidden.
Also never use solvents such as kerosene, acetone
or thinner.

7. TESTING A NEW UNIT

Since the KF-234 PG2 is supplied with the battery already
installed, the unit is practically ready to be tested.
A. Stand 3 m (10 ft) away from a target control panel (or

wireless control panel) and press the ARM AWAY
button (see Fig. 2). Verify that the red LED lights upon
transmission and that the green LED lights upon
acknowledgement from the PowerMax10-G2.

B. Make sure that the control panel responds as

programmed and as stated in the control panel’s
instruction manual.

8. MISCELLANEOUS COMMENTS

8.1 Product Limitations

Visonic Ltd. wireless systems are very reliable and are
tested to high standards. However, due to their low
transmitting power and limited range (required by FCC and
other regulatory authorities), there are some limitations to
be considered:

A. Control panels may be blocked by radio signals occurring

on or near their operating frequencies, regardless of the
code selected.

B. Wireless equipment should be tested regularly to

determine whether there are sources of interference
and to protect against faults.

5. LOCAL DIAGNOSTICS TEST

Before testing, separate the base from the cover (see Fig. 5).

A. Press the front tamper switch once and release it.
B. Put back the cover to return the tamper switch to its

normal (undisturbed) position, and then secure the front
cover to the base with the case closure screw.

C. Walk-test the coverage area - see fig. 2. Walk across

the far end of coverage pattern in both directions, The
red LED lights each time your motion is detected
followed by 3 LED blinks.

The following table indicates received signal strength
indication.

LED response Reception

Green LED blinks Strong

Orange LED blinks Good

Red LED blinks Poor

No blinks No communication

IMPORTANT! Reliable
reception must be assured.
Therefore, "poor" signal
strength is not acceptable. If
you receive a "poor" signal
from the detector, re-locate
it and re-test until a "good"
or "strong" signal strength is
received.

Figure 4. General Guidelines

Important! The K9-85 detector is immune to 38 kg (85 lb)
animals moving on the floor or climbing on furniture as long as
the activity takes place below 1 m (3 ft). Above the 1 m (3 ft)
height limit, the detector is immune to 19 kg (42 lb) pets, but the
pet immunity will decrease as the pet gets closer to the
detector. It is therefore recommended to select a mounting
location that minimizes potential close proximity of animals.

7. SPECIAL COMMENTS

Even the most sophisticated detectors can sometimes be
defeated or may fail to warn due to: DC power failure /
improper connection, malicious masking of the lens,
tampering with the optical system, decreased sensitivity in
ambient temperatures close to that of the human body and
unexpected failure of a component part.

The above list includes the most common reasons for
failure to detect intrusion, but is by no means
comprehensive. It is therefore recommended that the
detector and the entire alarm system be checked weekly, to
ensure proper performance.

An alarm system should not be regarded as a substitute
for insurance. Home and property owners or renters
should be prudent enough to continue insuring their lives
and property, even though they are protected by an alarm
system.

This device has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in
residential installations. This equipment generates uses and
can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause
harmful interference to radio and television reception.

NEXT PG2, NEXT-K9 PG2

D-302758 7

However, there is no guarantee that interference will not
occur in a particular installation. If this device does cause
such interference, which can be verified by turning the
device off and on, the user is encouraged to eliminate the
interference by one or more of the following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.

– Connect the device to an outlet on a circuit different from

the one that supplies power to the receiver.

– Consult the dealer or an experienced radio/TV technician.

WARNING! Changes or modifications to this unit not
expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.

SMOKE SENSORS (SMD-426, SMD-427)

Supervised Wireless PowerG Smoke / Heat and Smoke Detector

1. DESCRIPTION AND APPLICATIONS

SMD-426 (smoke detector) and SMD-427 (heat and
smoke detector) are automatic fire detectors with integral
audible signal for open area protection, designed to sense
heat or smoke (not flame) and fitted with a PowerG type
UHF transceiver.
SMD-426 / SMD-427 provides early warning of developing
fire by sounding an alarm with its built-in alarm horn, and
by transmitting a coded alarm signal to a PowerG receiver
or to a compatible wireless alarm control panel.
SMD-427 will activate a fire alarm upon either smoke or
heat (temperature rate-of-rise) condition. With two fire
sensors (heat and smoke), the SMD-427 detector may
shorten the time to fire alarm activation.
It must be borne in mind, though that effective prewarning
of fire accidents is only possible if the detector is located,
installed and maintained as described here.
In alarm condition, the buzzer sound can be stopped for 12
minutes by pressing the TEST/MUTE switch. It will not
restore the alarm condition, but will temporarily silence the
buzzer while you correct the condition. After 12 minutes, the
detector restarts the alarm buzzer sound.

Note: The TEST/MUTE switch functions as TEST switch
(in normal operation) or as MUTE switch (in alarm
condition).

The tamper switch actuator (Fig. 3) is pressed against the
bracket when the unit is attached to the bracket. Removal of
the unit from the bracket causes the switch contacts to open,
creating a tamper event, which is reported by the transceiver
to the alarm system control panel.

Tamper Alerts: Tamper event (removal of the unit from its

the tamper switch is restored.

ALARM REPORT:

In the alarm condition, the detector sends the alarm event
to the control panel. When the alarm condition is restored,
the detector sends an alarm restore event to the control
panel and sets the alarm restore indication (red LED blinks
once per sec.)

Note: The alarm restore indication can be cleared via the
control panel only.

Warning: Built-in horn beeps every 30 seconds in the

middle of red LED flashing intervals – indicates that the
detector must be replaced.
Clean Warning Transmission: A clean (maintenance)
