BGU—Break Glass Unit
The BGU is used to override the Access control system which will release the maglock in case of an emergency exit. When the BGU is activated (Lift the cover and press in the middle of the BGU), the RED LED of the BGU turns to flashing red and beeps. This indicate the door is in an override mode and the maglock will be released.
To bring the BGU to normal state a special key is provided.
The BGU is always installed on the secure side of the door.
ORK—Override Key Switch
Override keys are special keys that can be used as follow:
To isolate power to the maglock, to allow access through a door.
To silence an activated siren on an emergency exit door,
To silence a DHO (Door Held Open) DFO (Door Forced Open) E.g. DC doors and MMR doors.
The door turns back to normal state.
Maglock 
The maglock is used to secure a door by electrically magnetising the unit.
The maglock has a build in contact to provide a door open or door closed trigger on the software associated to the installation.
When the electromagnet is energized, it attracts an armature plate, securing the door (maximum 3mm gap).
Maglocks require constant power to remain locked. They function using a fail-safe system,
where power ensures that the door stays locked.
ZL Bracket
The ZL bracket is used to install a Maglock to the secure side of a door if the door opens to the secure side as this is important if the maglock is on the unsecure side, it creates a potential for a security breech.
This could be installed in various positions.
Custom options are also available.
Electronic Shear-Lock
The Shear-Lock has a built-in micro controller with door open delay time and door position detection outputs. Suitable for all types of 90 degrees to 180 degrees open aluminium or wooden doors.
Accuracy is very important on this lock installation this is less than +/-3mm
It has a maximum shear force of 1,200kg and maximum magnetic action up to 5mm.
Pinlock (Bolt lock)
The Pinlock (Bolt Lock) is installed on sliding doors (Cages). Pinlock (Bolt Locks) are installed from single sliding door to multiple sliding doors. Pinlocks arelocked or unlocked with the assistance of an electrical current. The electrical current is either used to power an electromagnet, a solenoid electromagnet with a single coil.
NB in the event of no power these pinlocks will disengage and the doors will be free to open.
EL 560 Mortise lock
The EL 560 Lock Mortise lock are installed on high security doors like DC, DC security offices and client offices on request. Installation of this lock must always be referred to the manual and wiring diagram as the colour coding of cables may differ. When the door closes, the lock engages automatically – the dead bolt throws out and the latch bolt is locked (Refer to manual). When access is granted the controlled handle or panic handle is down, the dead bolt is withdrawn inside the lock case and the latch bolt is released concurrently.
NB this lock is also used with an ORK and manual lock key.
Electric Striker Lock
This image is for an example only.
An electric strike lock is a type of locking device that is used in conjunction with an existing/ standard door lock. When the door is opened, the strike plate is retracted, allowing the door to be opened.
When the door is closed, the strike plate extends, preventing the door from being opened. Electric strike locks can be used on both inward and outward swinging doors. They are available in a variety of sizes. Mechanical override available.
Siren
The siren is used to activate when there is a breech in security.
Example would be when an emergency exit door is opened the siren will sound and alert the security or if a door is open for too long.
Isolator Monitor(Power Monitor)
The Power Monitor (Isolator Monitor) is connected to 220v that is supplied to the PSU. If the 220v power supply drops the Power Monitor (Isolator Monitor) will change state and indicate that there is no 220v to the system.
HBUS Door Module 4in 2out
The HBUS 4 In 2 Out, Door Module – Wiegand by Gallagher is designed to enhance the connectivity of the Gallagher Controller 6000 using the HBUS communications protocol. Let’s break down how it works:
Inputs and Outputs: The module provides connections for: 2 Wiegand Readers: These are used for access control, allowing users to present credentials (such as cards or fobs) to gain entry. 4 Inputs: These can be used for various purposes, such as monitoring door status (open/closed), detecting tampering, or integrating with other systems (e.g., fire alarms). 2 Outputs: These outputs can trigger actions, such as unlocking the door, activating an alarm, or controlling external devices (e.g., lights or sirens).
Functionality:
When a user presents their access credential (e.g., swipes a card), the Wiegand reader sends the credential data to the Gallagher Controller 6000. The controller processes this information and determines whether access should be granted. If access is granted, the controller activates the appropriate output (e.g., unlocking the door). Inputs can also be configured to trigger specific actions. For example, an input connected to a fire alarm system could cause the door to unlock during an emergency.
Integration:
The module seamlessly integrates with the Gallagher security ecosystem, allowing for centralized management and monitoring. It ensures secure communication between the controller and connected devices. In summary, the HBUS 4 In 2 Out, Door Module – Wiegand facilitates access control by handling reader inputs, monitoring door status, and controlling outputs based on predefined rules. It’s a crucial component for secure and efficient building access management.

Diode 4007
It acts as a one-way switch that allows the current to flow in one direction and halts in the other direction. 1N4007 belongs to the silicon family of1N400X series. It is a general-purpose rectifying diode that serves its purpose of converting alternating current signals (AC) to direct current signals (DC) in electronic products.
Resister 4K7
A resistor’s primary purpose is to limit the flow of electric current in a circuit. It does this by providing resistance. The resistance value is measured in ohms (Ω). In the case of a 4.7k ohm resistor, the value is 4,700 ohms. Colour Code: The colour bands on the resistor indicates its value. Let’s decipher the colour code for a 4.7k ohm resistor: Yellow (1st band) represents the first digit, which is 4. Violet (2nd band) represents the second digit, which is 7. Red (3rd band) acts as the multiplier, indicating a factor of 100. The gold band (4th band) specifies the tolerance, which is ±5%. In summary, a 4.7k ohm resistor helps regulate current flow in electronic circuits, ensuring stable operation of devices.
Metal Oxide Varistor (MOV)
It contains a ceramic mass of zinc oxide grains sandwiched between two metal plates. When the voltage across the MOV is below the ‘clamping voltage’ or ‘varistor voltage’, it behaves as a high-resistance component. If the voltage increases, the resistance decreases, making it useful for protecting circuits from high voltage spikes.
