MCT/IR-252 WP S
Resettable Dual RF & IR Waterproof Transmitter
User Guide
1. INTRODUCTION
The MCT/IR-252 WP S is a miniature, water-proof, resettable,
microprocessor controlled, personal transmitter designed for use in
the SpiderAlert signaling network. The transmitter is used ONLY
during emergencies involving security and safety of life, such
that when an alarm is activated, transmissions continue during
the pendency of this alarm condition. Application examples
include elderly hospital patients and emergency nurse calls. The
transmitter has two buttons, used for reporting three different
emergency events: PANIC1 (large button), PANIC2 (small button)
PANIC3 (by clicking on the two buttons simultaneously). The alarm
events are supposed to be acknowledged and reset by the person
who responds to the alarm message by holding a magnet close to
the pendant. In the case that an event is not acknowledged, a No
Response message is sent. In addition to the above-mentioned
events, the transmitter also sends low-battery and supervision
messages (when defined in DIP switch). The transmitter transmits
coded UHF signals and pulsed infrared signals simultaneously,
thereby allowing the target receiver to accurately determine the
specific point at which transmission took place in multi-storey
buildings.
Besides the regular alert mode, in which an alert message is
transmitted only once, the transmitter can be set to two additional
modes – MESSAGE CYCLE and REPEATED MESSAGE
CYCLING. In the message cycle mode, PANIC1, and PANIC2
messages are automatically repeated three times (initially 4 times),
and a no-response message follows if the message has not been
acknowledged. In the cycle repetition mode, a sequence of three
alarm messages followed by a no-response message (one cycle) is
repeated 5 times, unless the message is acknowledged sooner.
The time interval between these messages is determined by the
DIP switches (para. 3.1). When a PANIC1 message is transmitted
after an PANIC2 message has been initiated, the repeated
messages will be PANIC1 messages instead of PANIC2 messages.
When holding an external
magnet close to the unit
pushbuttons, either from
underneath or on top, (fig. 1),
the repetitive message
transmissions stop and an
acknowledge message is sent.

16 million code possibilities, so for all practical purposes no two
transmitters will have the same ID code. The dual-technology alert
transmissions made by the MCT/IR-252 WP S are directed at
SpiderAlert receivers. These receivers are strategically located all
over the surveillance area, to pick up alert transmissions and report
the ID code of the transmitter whose signal was picked up.

Reporting is accomplished via a two-wire bus routed to the
SpiderAlert Local Control Unit SLC-5, that collects and transfers all
data to the SpiderAlert main computer automatically displaying the
holder’s name and exact location. All units are supplied with a
chain, to be worn around the neck as a pendant transmitter.
