5.2.5 Lock Output

Figure 24 Lock Output Wiring

All locks should be fitted according to the manufacturer's instructions.

The door controllers provide a lock output for each reader channel. These outputs are capable of

providing either 12V dc or 24V dc. The lock output on each channel must not be able to exceed 1.0A at

12V dc or 0.5A 24V dc. The lock voltage is set using a switch accessible through the top of the power

supply unit.

Each lock output is protected by resettable fuse on the controller. Two status LEDs are also provided for

each lock output. These operate as follows:

• Fail Safe Locks. Both the red and green LEDs are normally on. When a valid key is presented to a

reader, both LEDs go off for the duration of the lock release time. A fault is indicated when only the

red LED is lit.

• Fail Secure Locks. Both the red and green LEDs are normally off. When a valid key is presented to a

reader, both LEDs come on for the duration of the lock release time. A fault is indicated when only the

red LED is lit.

Each output can be independently set as fail-safe (power to lock) or fail-secure (power to unlock).

The cable between the door controller and the lock should be of such a gauge as to provide at least the

minimum voltage required to operate the lock. The resistance of the cable and the current drawn by the

lock will determine the type of cable.

5.2.5.1 Lock Suppression

All locks must be fitted with a means of suppressing back Electro-Motive Force (EMF) 'spikes' generated

by most electric releases, especially magnetic locks. All PAC Portico door controllers and readers are

supplied with Metal Oxide Varistors (MOVs). If large currents are used (i.e. >1A) use the large MOV

supplied with the door controller. If small currents are used (i.e. <1A) use the small MOV supplied with

the reader.

The MOV will prevent long term damage being done to the door controller. Whenever possible this device

should be fitted across the lock terminals. If for any reason, the lock terminals are inaccessible, the MOV

may be fitted across the lock output.

5.2.5.2 Safety

Any door that is considered a fire door or is on an escape route must have some means of overriding the

electric release in an emergency. Usually this is achieved by the use of fail-safe locks (power to lock)

fitted with a normally closed break-glass in the lock supply. When the break-glass is operated, the

supply to the lock is broken and the door will be released without any intervention from the door controller.

5.2.6 PIN Reader

A PIN reader operates exactly as a normal reader except that the user has to enter a PIN after presenting

their key.
