Bosch Photobeam 5000 Series ISC-FPB1-W60QF Four Channel Quad-Beam Photoelectric Detector, 393' Indoor and 196' Outdoor Maximum Range

The detector series uses four pulsed infrared beams that are designed to activate an alarm when all four beams are simultaneously blocked. False alarm immunity is increased by the utilization of four beams compared to single or dual beam models. The detector series also features interlocked upper and lower beams, signal voltage LED and optional environmental discrimination circuitry.

• Quad beam detection
• Environmental discrimination circuit
• Beam power control to reduce cross-talk

System overview
Consisting of a separate transmitter and receiver, it is designed to activate an alarm when an intruder passes within the direct line of sight between the transmitter and receiver.

Mounting Functions
Mounting and installing the detector is now easier than ever. Install the detector through easy-to-use mounting hole locations which provide an enlarged entry point of access to accept small to large, single or multiple cable set wires. Fastening screw locations eliminate the need for unnecessary crawling or bending during installation.

Multiple Channel Operation
Configure the detectors for up to four different channels. This allows multiple units to be used near one another without the possibility of receiver crosstalk. This is particularly useful when stacking multiple beam sets.

High Density mode
The High Density mode allows you to add an additional zones of protection to detect larger objects that only partly interrupt the beams of individual devices. This feature allows an alarm condition to be generated when beam pairs are interrupted on adjacent devices but not all four beams are interrupted on one device.

Selectable AND/OR mode
This feature allows an added level of detection by generating an alarm when four beams from two units are blocked simultaneously. Environmental conditions require higher false alarm tolerance against smaller objects passing through the detector's line of sight. To do this, set the AND/OR gate option to AND gate mode that only causes an alarm condition when all four infrared beams are interrupted simultaneously.

High Security applications might require the detection of smaller objects passing through the detector's line of sight. To do this, set the AND/OR gate option to OR gate mode that causes an alarm condition when either the upper two beams or the lower two beams are interrupted.

Dust/insect cover Functions
The included foam sealing ensures that the detectors are properly secured from insects and other environmental elements such as humidity and temperature fluctuations. The improved cover design includes water flow channels to prevent water and dirt from accumulating in front of optic components and eliminates the need for additional weatherproofing solutions.

Environmental Discrimination Circuit
Monitors gradual loss of signal due to dust, fog, rain and snow. Normally closed output opens when signal loss reaches 90%. May be field configured to bypass alarm relay when activated.

Beam Power Control
The transmitter power output is field adjustable allowing the user to eliminate reflections and crosstalk from other units. This feature improves catch performance and false alarm immunity and allows for reliable installation in most applications.

Test Functions
High visibility reception level LED improves ease of installation. Flash rate increases as installation alignment improves. Voltage output terminals also allow for improved alignment accuracy. Optical module alignment switch to allow for independent adjustment of upper and lower beam pairs.

Dual Modulated beam
The Dual Modulated Beam eliminates interference from external noise sources such as sunlight, car headlights, electrical interference, etc.
