eight Addresses should share an S-Bus. See WRM Address Information
on page 17 for Address usage with one Reader connected.

Digital Inputs

General

Type .............................................

2 Dry-contact inputs with End-of-line (EOL)

Sensing and 2 Dry-contact inputs without End-

of-line (EOL) Sensing.

Detection Resistance Range ......

< 2 kOhm.

Protection Range .........................

+15 V continuous.

Figure 1: End-of-line (EOL) Sensing Circuit

NOTE: End-of-line (EOL) Sensing enables the WRM to raise an alarm when

somebody tampers with the circuit (cutting or shorting the wires) between
either Reader 1 Inputs [1] DOS or Reader 2 Inputs [2] DOS and GROUND
(GND). In other words the Module distinguishes between tampering on the
circuit, and the door being in an actual ‘Normally Open’ state.

By placing Resistors into the circuit between either Reader 1 Inputs DOS [1]

or Reader 2 Inputs DOS [1] and GROUND (GND), the Module’s Digital Input
monitors a constant resistance through the circuit. When the circuit is
tampered with, the Resistors are bypassed; the Module detects the
resistance change and raises an alarm.

LED Status and Diagnostic Indicators

Status LED (RED)

Supply Voltage Status ............

Off when supply voltage is too high, or too low

Upgrade Mode .......................

Flashing at a steady rate during upgrade

Communications Failure ........

Two brief flashes, repeating

Data LED (GREEN)

Flashing Green during communication

Digital Inputs (1-4) ......................

Continuous Green on detected contact closure

Relays (1 and 2) ...........................

INSTALLATION INFORMATION

Accessories

CAUTION: DO NOT use the Metal-oxide Varistors (25 Vrms, 500 A, 77 V max

clamping) with mains power applications.

Plastic Cluster Housing (HMW700)

Each Impro (WRM) Wiegand Reader Module is supplied in a Customisable Black, ABS
Plastic housing, with the following features / items:

• Housing, consisting of a Base, a Cover and a selection of Cable Entry Gland
Plates.

• The Housing Base has:

− Two slots to hold the User-Selectable Cable Entry Plates

− Six knock-out Cable Entry Points

− Four Drill-out Cable Entry Points

• The Housing Cover and Base are held together with two Allen Head Screws

(M4 x 10 mm) through the cover of the housing.

• Five Ziploc bags, containing the following:

− Four Stand-Offs (for spacing the WRM away from the mounting surface)

and two Cluster Connector Covers (for closing off the cluster connectors
when not in use.)

− Two Metal-Oxide Varistors 25 Vrms, 500 A, 77 V max clamping.

− A 2mm Allen Key and a spare Hex Head Screw

− Two extra gland plates

− An extra Fixed Address Label, for installation site mapping

NOTE: The installer needs to obtain fasteners (< 5 mm Diameter to fit through the

supplied Stand-Offs) that are suitable for securing the Module to the
mounting surface – these are NOT supplied in the kit.

PCB Card for IPS Housing (HMW710)

Included in the packaging is:

• Impro Wiegand Reader PCB Card on a Base Plate.

• An extra Fixed Address Label, for installation site mapping

General

Remember the following when installing the Wiegand Reader Module:

Clustering

Clustering allows for the easy addition or replacement of Modules, it saves on wiring
and requires only one DC Power Supply connection for the Cluster.

The following applies:

• The WRM may be plugged directly into its associated Cluster Controller, or
into an existing Cluster consisting of a Cluster Controller and other Expansion
Modules.

• No more than eight Expansion Modules can be clustered with their associated
Cluster Controller.

• The WRM is powered and controlled via its Cluster Connector.

• Clustering with the Cluster Controller is recommended where Offline

Validation is a high priority, as the WRM will have reliable access to the Tag
Buffer and Memory on board the Cluster Controller.

S-Bus

S-Bus is useful when it would be convenient to install a WRM some distance from its
Cluster Controller. The following applies:

• The maximum S-Bus Cable length from the Cluster Controller to the WRM is
150 m (490 ft.).

• A maximum total of 8 addresses may be connected to the S-Bus.

• The S-Bus cable should be dual core and at least 0.21 mm2 (AWG24).

Screened cable is recommended where interference rejection may be
necessary in electrically noisy sites – and to provide SOME MEASURE* of
resistance to damage from nearby lightning strikes.

• Remotely mounted WRMs will also require a suitable Isolated DC Power
supply, as they are no longer plugged into the Cluster Controller.

• In the event of the S-Bus cable breaking, the WRM will stop working.

NOTE: *NOTHING can survive a direct lightning strike. Impro Technologies does

NOT claim that its products are lightning proof.

A more detailed chapter on S-Bus is included in the Impro (CCM) Cluster

Wiegand or Multi-Discipline Reader Distance

CAUTION: When implementing the 150 m (164 yd) cable distances with Impro

Wiegand Readers use the 12 V power output option. Note, however,
that the Multi-discipline Readers only connect using the 12 V power
output option.

For maximum, data communications distance, install the Readers no further than
150 m (164 yd) from the Terminal The cable individual conductor cross-sectional area
should not be less than 0.2 mm

2

(0.0003 in2).

Distance between the WRM and its Multi-mode Remote

The maximum cable distance between the Impro WRM and its Multi-mode Remote
MUST NOT exceed 10 m (33 ft). Achieve this by using good quality screened, twisted
pair cable.

Distance between Reader Units

To avoid mutual interference, install the Readers at least 500 mm (20 in) apart. (The
same rule applies between readers on opposite sides of the same wall.)

EARTH Connection

Connect the Impro WRM (“ETH” Terminal) to a good EARTH point. Mains EARTH can
be used, but electrical noise may exist.

Arc Suppression

Snubber devices are recommended for EMF Flyback and Arc Suppression when
driving an inductive load with the Relay, see Figure 2.
