Introduction
Installation
The 4090-9118 Relay IAM with T-Sense provides the 4100U FACP output control of one Form-C contact set and input status from a T-Sense monitoring zone. The
Relay IAM with T-sense provides the 4100U FACP with the status/state of the monitored zone. The 4 states that it can indicate are: OPEN, NORMAL,
LIMITED, and SHORT. The LIMITED state occurs when a normally-open device, electrically located between the series resistor and the EOL resistor, activates. The FACP can then annunciate the status of closed devices depending on whether they are before or after the series resistor.
The IDNet channel provides the communication link between the Relay IAM with
T-Sense and 4100U FACP while powering the entire circuit.
The range of possible temperatures under which the 4090-9118 Relay IAM with T-
Sense can function is between 32
°
F (0
°
C) and 120
°
F (49
°
C). This Relay IAM operates normally under non-condensing humidity conditions up to 93% relative humidity at 90° F (32° C).
Relay IAM with T-Sense installation consists of the following:
•
Setting the address of the Relay IAM with T-Sense
•
Making electrical connections to the Relay IAM with T-Sense
•
Mechanically installing the Relay IAM with T-Sense

Setting the Address of the
Relay IAM with T-Sense
Note: The IDNet channel supports address codes 1 through 250.
Each Relay IAM with T-Sense has a unique address. The address of the Relay
IAM with T-Sense is set via an eight position dip switch (Figure 1). DIP switch position 1 is the least significant bit (LSB) and position 8 is the most significant bit (MSB). Set the address using Figure 2 as reference. Use a small screwdriver or pen to set the switches. The device address for the Relay IAM with T-Sense should be written on the re-sealable label; this information provides an aid in troubleshooting the system.
Note: DIP switch in “1” position is “ON” while DIP switch in “0” position is “OFF”.

Notes:
1.
Maximum allowable run from FACP to farthest device is not to exceed 2,500 feet
(762 meters). Maximum total wire (including all T-Taps) from FACP is 10,000 feet
(3,048 meters). IDNet lines are 18 AWG (0.823 mm/squared) twisted pair (shield recommended). When using shield, wire nut, splice, or solder the shield wires. Also insulate shield from the electrical box.
2.
The Relay IAM with T-Sense counts as a one-unit load.
3.
IDNet wiring is supervised and Power-Limited. An IDNet circuit has a communications power rating of 36.25 volts (maximum) at .5 A, 3333 Baud.
4.
Contractor wiring to relay contacts is unsupervised. Wire to local code (14 AWG
[2.081 mm/squared] recommended with 12 AWG [3.309 mm/squared] maximum).
Relay contacts are rated for 2 A (1 A for inductive load), 30 VDC and .5 A (0.25 A for inductive load), 120 VAC (non-power-limited). Inductive loads must be suppressed with a suitable suppression device. If switching 120VAC, the power source to the contacts should be externally fused by the user with a 1 Amp 250V quick blow fuse, UL listed to Guide #JDYX – Littlefuse AGC1 or equivalent. For power-limited operation, power must be provided from a power-limited auxiliary power output from the FACP or from a power-limited output of a power supply listed for fire protective signaling use. When both power-limited and non-powerlimited sources are present, use Type FPL, FPLR, or FPLP power-limited cable for power-limited circuits. If the relay is used to control a fire safety function, it must be wired within 3 feet (91.44 cm) of the control circuit. Provisions to conform to NEC
760 power-limited and non-power-limited wiring separation must be made in the field wiring if non-power-limited wiring is used on the relay output.
5.
If AC is used on relay terminals, you must add Label 526-831 to electrical box cover to indicate high voltage, ground electrical box and bracket to safety ground, and wire input circuit with twisted-shielded wire (shield connected to grounded bracket).
6.
T-Sense input circuits are not to exceed 500 feet (152.4 meters). Only Normally
Open (N/O) dry contacts are allowed on the input circuits. T-Sense lines are 18
AWG (0.823 mm/squared) wire. T-Sense inputs are pulled up to 5 VDC by a 17.4 K resistor, which can source up to 287 uA (supervised and power-limited). T-Sense inputs may be tested using ¼ watt, 1% resistors as follows: 6.81 K (normal), 16.9 K
(open), 1.65 K (current-limited), & 845 Ohms (shorted).
7.
Relay function is programmable.
