Enforcer X 280 H Installation Guide

Case tamper connector

Connects the main PCB to the tamper switch on the metal housing of the endstation.

ATE connector

The ATE PGMs are connected to a third party signalling device in order to power the device and to send signals to a monitoring station.

Communication module slots

The communication module slots can accommodate any two of the following modules:

• Wi-Fi module – Must always go in comm slot 1
• 4G/2G module – Can go in either or both slots

Endstation LED indicators

The Endstation LEDs indicate the status of the following:

• RS485 bus
• Outputs
• Fuses
• Heartbeat
• Zones

Ethernet port

Once connected via a LAN cable to a network, it can be used to signal via IP to a central station or to communicate with InSite Pro Cloud. It can also be connected to directly with a PC/laptop for an InSite Pro Local connection.

Programmable outputs (PGMs)

There are two clean relays on the board and 4 transistorised outputs.

The 2 relay outputs are rated at 3A@30VDC each. Both relays have a 3-pin jumper which can be used to apply a voltage to the common of the relay. Placing a jumper linking the top two will make the common 12VDC and when the bottom two are linked, the common will be 0VDC.

The 4 transistorised outputs are rated 200mA@12VDC each and can operate in four different modes:

E-Fuse reset button

Resets all the electronic fuses on the board if any of them have tripped. (The fuses can also be reset through the engineer menu).

Transformer connector

Connects the incoming power to the endstation. Click here for power supply specifications.

External bell terminals

Terminals for wiring an external bell to the control panel. Click here for external bell wiring.

Engineer keypad Port

Is used to connect a temporary engineer keypad to.

3.15A anti-surge battery fuse

Sit in between the PCB components and the battery to protect the board and battery from issues such as reverse polarity.

8 zone expander port

For future use.

USB port

The USB port can be used for the following features:

• Import and export panel configuration
• Exporting panel logs

Battery connect button

Forces the relay that connects and disconnects the battery circuit to switch and connect the battery to the endstation. This is particularly useful to power up the endstation when there is no incoming mains supply to the panel.

Microphone and speaker terminals

Terminals to wire in an external microphone (for future use) and an 10W, 16Ω AC extension speaker.

Zone terminals

The zone terminals are in a Z1, COM configuration and can be wired in any of the following:

• Double pole (N/C or N/O)
• Single end of line (SEOL)
• Double end of line (DEOL)
• Triple end of line (3EOL)

RS485 bus terminals

All keypads, proximity readers, wired and wireless expanders (both zone and output) are wired to these terminals.

RS485 End of Bus (EOB) resistors

Above the RS485 terminals, each bus has its own EOB two-pin jumper header. If the RS485 bus needs a terminating resistor, the respective jumper is used to incorporate a 100Ω terminating resistor across the data line at the endstation. If this is used, a 100Ω resistor should be fitted at the furthest point of the bus across the D3 and D4 terminals.

E2 RS485 bus

For future development.

Back-up battery connection

Connects the battery to the endstation.

Most of the LED indicators are only active when the system is in engineer mode’. The only LEDs which are always active are the ‘Heartbeat’ LED and the communication LEDs.

RS485

This section of LEDs show the status of the RS485 terminals. When a device is wired into these terminals and programmed to be active, the LED will illuminate.

	No LEDs will be illuminated when there are no devices connected to the RS485 terminals		RS485 Bus1 When a device is wired into ‘RS-485 BUS1’ and programmed, the green LED next to ‘BUS1’ will illuminate.
	RS485 Bus2 When a device is wired into ‘RS-485 BUS2’ and programmed, the green LED next to ‘BUS2’ will illuminate.		E2 RS485 Bus This is for future use.

RLY and O/P Outputs

When the relevant output is triggered, the LED for that PGM output will illuminate and then extinguish when it returns to a quiescent state.

	When all the PGM outputs are in a quiescent state, none of the LEDs from this section will be illuminated.		Relay O/P1 When this relay is triggered, the orange LED next to ‘RLY1’ will illuminate.
	Relay O/P2 When this relay is triggered, the orange LED next to ‘RLY2’ will illuminate.		Transistor O/P3 When this output is triggered, the orange LED next to ‘O/P3’ will illuminate
	Transistor O/P4 Then this output is triggered, the orange LED next to ‘O/P4’ will illuminate.		Transistor O/P5 When this output is triggered, the orange LED next to ‘O/P5’ will illuminate.
	Transistor O/P6 When this output is triggered, the orange LED next to ‘O/P6’ will illuminate.

Faults

All fuses except the battery fuse are thermal fuses and can be reset by pressing and holding down the ‘E-FUSE RESET’ button in the middle of the PCB. They can also be reset in the Engineers menu in the option ENGINEER MAINTENANCE > Reset Efuses.

	When the control panel is healthy and none of the fuses are tripped, no LEDs will be illuminated.		Auxiliary Fuse This fuse will be tripped if the current drawn from the AUX terminals exceed the limit. Recommended 1.0A Maximum 1.5A
	Self-Actuating Bell (SAB) Fuse This fuse will be tripped if the current drawn from the SAB terminals exceed the limit. Recommended 1.5A Maximum 2.0A		Zones Fuse This fuse will be tripped if the current drawn from the 12VDC terminals that supply the zones exceed the limit. Recommended 1.0A Maximum 1.5A
	RS485 Bus1 Fuse This fuse will be tripped if the current from the RS485 BUS1 terminals exceed the limit. Recommended 1.0A Maximum 1.5A		RS485 Bus2 Fuse This fuse will be tripped if the current from the RS485 BUS2 terminals exceed the limit. Recommended 1.0A Maximum 1.5A
	E2 RS485 Bus Fuse For future use. Recommended 1.0A Maximum 1.5A		Battery Fuse This is a glass anti-surge timed blow fuse and will blow if the current drawn from the battery exceed the limit. Maximum 3.15A

Heartbeat

The ‘Heartbeat’ LED indicates that the control panel processor and firmware are running correctly.

Zones

The zone LEDs are tri-colour to visually display all states that the zone can be in and not illuminated if the zone is not programmed. The below examples show the various states that the first zone can be in.

When an zone is programmed as ‘Unused’ the LED will not illuminate.	When the zone is in a restore or ‘healthy’ state, the LED will illuminate green.	When the zone is in an alarm or ‘open’ state, the LED will illuminate blue.	When the zone is in tamper or ‘trouble’ state, the LED will illuminate orange.	If the zone is masked, the LED will flash orange.

Cable Type and Range

General Principles

• No alarm system cable should be run with other cables carrying AC or digital signals.
• The cables should be protected by the use of grommets where appropriate.
• If an expansion module with a power supply on board is connected, the D2+ terminal must not be connected between the main bus and module.

Devices

The RS485 bus is used to communicate with peripherals that transfer and receive data. The main devices that are wired on to the RS485 bus are keypads, tag readers, zone expanders and PGM output expanders.

Keypads	Proximity readers	Zone expanders	Output expanders

Resistors

Each circuit is made up of one, two or three resistors depending on whether the circuit is being wired single end of line (SEOL), double end of line (DEOL) or triple end of line (3EOL). There are multiple terms that are used to describe the different states a circuit can be in, some of these are as follows:

This circuit is comprised of two resistors.

1. The alarm resistor which will indicate to the control panel when the zone has been triggered and is in an ‘alarm’ state.
2. The end of line resistor which indicates to the control panel that the circuit is healthy and the tamper is closed.

A typical example of this is below, showing the circuit and the resistors wired in a DEOL configuration.

Resistor
Tamper switch

	Alarm resistor 4k7		Tamper resistor 2k2
	Alarm terminals		Tamper terminals

Choosing the Correct Resistors

It is extremely important that the correct resistors are used when wiring the circuit. The EOL resistor is measured in the system all the time, when the detector goes into alarm, it adds this value to the EOL resistor . In the case of a masking scenario, the mask and alarm resistors are added to the EOL resistor allowing the control panel to distinguish four states – alarm, fault, mask and tamper. When selecting the resistors, it is vital to take notice of the range of each state and that, when added together, the resistance measured falls inside the range.

The below table shows the full range of resistances that can be selected in the control panel.

Again, using the examples of 4.7k/2.2k resistance range. The tolerance table is as shown:

The resistors that should be chosen

To wire in the 4.7k/2.2k resistor range, the resistors used should be a 2.2k for end of line, 4.7k for the alarm relay and 6.8k for the mask relay. The resistors will fall in to the ranges as follows when the zone changes states

• Normal state 2.2k
• Alarm state 4.7k + 2.2k = 6.9k
• Fault state 6.8k + 2.2k = 9k
• Masked state 4.7k + 2.2k + 6.8k = 13.7k

Double Pole

The zones can also be wired in a double pole configuration; meaning either normally closed or normally open. If the zone is wired in this configuration, it must be programmed to operate in 0k/0k.

If the zones are wired in a normally open configuration, the zone needs programming on the system to reflect this. This programming can be altered in engineer menu PROGRAM ZONES > Choose Zone > Zone Attributes > Normally Open.

An extension speaker should be wired between the -SPK and SPK+ terminals and should not be greater than 16Ω. It does not need programming and will follow the tones programmed in the panel such as chime and entry/exit tones.
