Introduction

Installation

4090-9118 Relay IAM with T-Sense

DO NOT INSTALL ANY SIMPLEX
DAMAGED. Upon unpacking your Simplex product, inspect the contents of the

carton for shipping damage. If damage is apparent, immediately file a claim with
the carrier and notify an authorized Simplex product supplier.

ELECTRICAL HAZARD - Disconnect electrical field power when making any
internal adjustments or repairs. All repairs should be performed by a
representative or authorized agent of your local Simplex product supplier.

STATIC HAZARD - Static electricity can damage components. Handle as
follows:

• Ground yourself before opening or installing components.

• Prior to installation, keep uninstalled component wrapped in anti-static

material at all times.

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 T­Sense 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

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.
