fixed heat detector and rate-of-rise. FIK-5351H will default to a 190°F
high temperature heat detector.
Intelligent programmable temperature sensors require compatible addressable
communications to function properly. Connect these sensors to listed-compat-
ible control panels only.
WIRING GUIDE
All wiring must be installed in compliance with the National Electrical Code,
applicable local codes and the Authority Having Jurisdiction. Proper wire
gauges should be used. The installation wires should be color coded to limit
wiring mistakes and ease system troubleshooting. Improper connections will
prevent a system from responding properly in the event of a fire.
Remove power from the communication line before installing sensors.
1. Wire the sensor base (supplied separately) as shown in the wiring
diagram. (See Figure 2.)
2. Set the desired address on the rotary dial switches. (See Figure 1.)
3. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
4. After all sensors have been installed, apply power to the control unit and
activate the communication line.
5. Test the sensor(s) as described in the TESTING section of this manual.

TAMPER RESISTANCE
Intelligent programmable temperature sensors include a tamper-resistant ca-
pability that prevents their removal from the base without the use of a tool.
Refer to the base manual for details on making use of this capability.
UL 521 listed for Heat Detectors
This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.
Before installing sensors, please read the system wiring and installation man-
ual thoroughly. This manual provides detailed information on sensor spac-
ing, placement, zoning, and special applications. Copies of these manuals are
available from Fike.
GENERAL DESCRIPTION
Models FIK-5351, FIK-5351, FIK-5351R, and, FIK-5351H, and are field pro-
grammable intelligent sensors that utilize a state-of-the-art thermistor sensing
circuit for fast response. These sensors are designed to provide open area pro-
tection with 50-foot spacing capability as approved by UL 521. The intelligent
temperature sensor can be programmed as either a 135°F fixed temperature
sensor, a rate of rise and 135°F fixed temperature sensor or a 190°F high tem-
perature sensor through the Fire Alarm Control Panel (FACP).
Two LEDs on each sensor light to provide a local, visible sensor indication.
Remote LED annunciator capability is available as an optional accessory
(Part No. RA100Z). Rotary dial switches are provided for setting the sensor's
address. (See Figure 1.)

Fike panels offer different feature sets across different models. As a result,
certain features of the Intelligent Programmable Temperature Sensors may be
available on some control panels, but not on others. These devices support
Fike IDP mode systems. The possible features available if supported by the
control panel are:
1. The sensor’s LEDs can operate in three ways—on, off, and blinking–and
they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-
trolled independent of the LEDs. Please refer to the operation manual for
the UL listed control unit for specific operation of these models
3. Devices are point addressable up to 159 addresses.
4. The heat sensor operates as a programmable heat detector.
NOTE: In panels where this feature is not available the FIK-5351 will
default to a 135°F fixed heat detector. FIK-5351R will default to a 135°F
