Locks & Accessories


Door Access Solutions


Door locking hardware compliments our range of intercoms and access controls for external and internal security doors. 


Electro locks & door releases

Fail secure locking that can be released by a control panel or access control, eg Intercom, keypad, button.

Locking magnets

Fail safe locking used as secondary security. Requires a holding power to remain locked. Used for additional security.

Power supplies and interfaces

All locks and access controls need power. Some applications also require timers and special interfaces.

Buttons, switches, and door loops

Security doors with access controls need simple user controls and connection materials. Personnel doors need releases in case of fire.

FAIL SECURE means that the door remains locked when power is lost. FAIL INSECURE locks unlock if the power fails.


Electro Locks & door releases


Automated gate control panels have electro lock outputs for addition physical security in the closed position. These locks are included as options to automation sets, but can be used on security doors.

Door releases are small electric latches for securing entrance and internal personnel doors, used with intercoms and other access controls.

Electro locks and door releases are  'power to release' types. Gate locks are high power, so check that the power supply and relay contact rating of the access controller. 

Fail secure door release have a knob on the secure side. Fail secure gate locks have a knob or button on the scure side, or a key release for applications where even the secure side can be reached.

Locking magnets (Maglocks)


Locking magnets, also known as 'maglocks', are 'power to lock' devices, also known as 'fail safe'. Supplies must be DC. Most gate controllers only have AC accessory power, but interfaces can be used to connect a locking magnet to a gate controller.

Locking magnets are rated by the maximum static weight they will hold in perfect conditions. However, a dirty surface or mis-alignment can drastically reduce effectiveness. Do not under estimated that a shock loading exerted can be many times the static weight.

Locking magnets are better suited to doors. A monitored magnet can let the access controller know that the door was not properly closed before power to lock was applied. An alarm can then be raised.

Locking magnets are 'fail insecure'. The lock releases when not powered. Battery backed up supplies are recommended for securty doors. Some magnets have LED indication. Some include timers to extend egress release time.

Power supplies and interfaces


DC power supplies used for locking magnets are relatively low power, but are ON for 99% of the time. All locks and magnets are inductive. Switch contacts and power supplies must have EMF protection.

Power supplies for gate locks and bolts are used for a few seconds, but at high current. Lock interfaces manage short high current pulses from a low current supply by storing the charge. 

Locking magnets on doors often use timers to extend the unlock time. so that a pedestrian has sufficient time to open the door. The access controller oftens covers that requirement with programmable relay times.

Gate control panels mostly provide 24Vac power, and have normally open lock switching. A maglock interface is used to connect the maglock to a gate control panel output.

Buttons & switches & door loops


The small accessories are often forgotten, but contribute to reliable gate or door access system. Mechanical outdoor exit buttons often deteriorate in harsh weather causing a malfunction.

Electronic buttons are fully sealed. Infra red buttons are non contact. Peizo buttons respond to a tap. Other technologies are available.

A useful facility is to be able to hold the door or gate open. 'Hold open' facility can be set on a keyswitch, or some buttons.

Another frequent failure point is the connection between a gate post and a gate ram. The continuous twisting causes the cable to fracture. An armoured door loop is a short length of armoured conduit that will protect the cable. Door loops also allows a cable to pass across a door or gate hinge.
