NOTE:
This equipment 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 a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with these instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment to a circuit different from that to which the receiver is
connected.
.-
- Consult the manufacturer or an experienced radiom technician for help.
GENERAL INFORMATION
The 2098-9207 is a long-range photoelectric smoke detector consisting of a separate transmitter and receiver. It protects
large areas where the use of individual spot smoke detectors is impractical or uneconomical.
The transmitter’s light source produces an invisible infrared beam. This beam is accurately measured by the receiver to
determine obscuration by smoke. If the beam intensity falls below the threshold set for alarm, a fire alarm is initiated.
Dust build-up and other long-term effects are cancelled out and do not reduce the sensitivity of the detector. An analog
output voltage can be measured remotely to help determine when cleaning is necessary. If dust builds up so that the
signal is reduced by 50%, a trouble output occurs. Because this detector is a sealed unit, it requires only external
cleaning. Intermittent beam blockage during cleaning is ignored. If complete beam blockage does occur, it only causes a
trouble output- not an alarm.
A sync line is not required between the transmitter and the receiver. Simplified installation requires only one-time access
to each unit; the transmitter is installed and aligned using internal bore sights before the receiver is in place. The receiver
has microprocessor-control circuitry allowing automatic calibration at the touch of a button. The crystal-locked transmitter
signature allows the receiver to distinguish the detection beam from all types of local noise sources such as fluorescent,
mercury, and sodium arc lighting.
