Electrified Door Hardware

Power Transfer, Power Supplies and Request to Exit Hardware

Electrified door hardware is the set of locks, power transfers, power supplies and switches that lets an access control system lock and unlock a door. PDQ makes the hardware side of the opening: electrified locks and exit device trim, electrified hinges and power transfers, wire harnesses, 24 VDC power supplies, and push buttons and key switches for request to exit.

What You Need to Electrify an Opening

Every electrified door needs the same six parts, in this order.

An electrified lock, strike or exit device. This is the part that locks and unlocks. Use the MR199 or GT199, the 6W99 trim or MLR on a 6300 exit device, or an electric strike.
A power transfer. It carries the wires from the frame into the door. Use the EL4 (4 wires), EL8 (8 wires) or EPT100 (12 wires). An electric strike mounts in the frame, so it does not need one.
A wire harness. The ISMC wire harness is a pre-assembled, plug-and-play cable that connects to the lock's molex connector.
A power supply. A PS Series power supply delivers 24 VDC to the hardware and links to the fire alarm.
A request-to-exit device. It tells the system someone is leaving. Use a push button or key switch, or the optional REX on the MR199 and GT199.
An access control system. PDQ does not make this part. Card readers, controllers and software come from your security integrator. For locks with no wiring at all, see PDQ Spirit electronic locks.

Compare PS Series Power Supplies

Model	Output Voltage	Amps	Outputs	Battery Backup
PS220	24 VDC	2A	2 PTC fused, plus 0.5A auxiliary	No
PS220B	24 VDC	2A	2 PTC fused, plus 0.5A auxiliary	Yes (batteries sold separately)
PS440B	24 VDC	4A	4 PTC fused	Yes (batteries sold separately)
PS480B	24 VDC	8A	8 PTC fused	Yes (holds two 7AH batteries, sold separately)

All four take a 110-120 VAC input, link to the fire alarm, protect against overload, short circuit and surges, control fail safe or fail secure locking devices, and are UL listed to UL 294 6th Edition. The PS220 and PS220B add a 0.5A auxiliary 24 VDC output for stand-alone devices such as keypads and motion detectors. All four carry a 3-year warranty.

How to Choose Electrified Door Hardware

PDQ GT199 electrified cylindrical lock

Step 1

Pick the locking device and the fail mode

Lever doors take an electrified lock or an electric strike. Exit devices take the MLR, the 6W99 trim or a rim strike. Then choose fail secure or fail safe. The MR199, GT199 and 6W99 change between the two in the field.

Step 2

Count the wires, then choose the power transfer

Count the conductors for the lock plus any REX or monitoring switch. Use the EL4 for one device, the EL8 for a lock with switches, or the EPT100 for up to 12 wires.

PDQ mushroom push to exit button

Step 3

Size the power supply and plan the way out

Total the in-rush current of every device on the supply, not the standby draw. Pick a B model if the opening must keep working in a power outage. Then add a push button or key switch for request to exit.

Where PDQ Electrified Hardware Fits

Access-Controlled Entries

Card and keypad entries need a lock that releases on command and a clear way out. Pair an electric strike or electrified lock with a power supply and a push to exit button.

Commercial Solutions

Aerial view of North Georgia Medical Plaza, a two-story stone and brick medical office building with a covered entrance canopy, large windows, and a landscaped parking lot surrounded by trees.

Healthcare

Hospitals and clinics lock staff-only doors while keeping egress free. Use battery backup power supplies so locks keep working in an outage, and the AL alarm kit on exit-only doors.

Healthcare Solutions

Schools

The MLR lets an access control system retract the latch on 6300 and 6400 exit devices for drop-off, then lock the entrance again. Key switches give office staff manual control.

Electrified Door Hardware FAQs

What do I need to electrify a door?

To electrify a door, you need an electrified lock, strike or exit device, a power transfer, a wire harness, a power supply, a request-to-exit device and an access control system. PDQ makes the first five. The access control system, including readers, controllers and software, comes from your security integrator.

What is the difference between an electrified hinge and an electric power transfer?

An electrified hinge is a door hinge with wires running through it, while an electric power transfer is a separate device that mortises into the door edge and frame. Both carry power into the door and stay concealed. The PDQ EL4 hinge has 4 wires and the EL8 has 8. The EPT100 has 12 wires, is rated up to 24 VDC at 1A, and is UL/ULC listed for fire doors.

What is a request to exit (REX) device?

A request to exit (REX) device tells the access control system that someone inside is leaving, so it can release the door. A wall-mounted REX button is the most common type. PDQ makes mushroom, narrow and wide push buttons and narrow and wide key switches, all in momentary or maintained versions. The MR199 and GT199 electrified locks also offer an optional built-in REX.

What size power supply do I need for electrified hardware?

You need a power supply rated for the total in-rush current of every device it powers, at the voltage those devices use. For example, the MR199 and GT199 draw up to 1.0A in-rush, the MLR draws 900mA, and the PS220 is rated to run two MR199 locks at once. PDQ power supplies output 24 VDC, from 2 amps on the PS220 and PS220B to 8 amps on the PS480B. Choose a battery backup model if the opening must work during an outage, and confirm sizing with your rep.

What is electric latch retraction?

Electric latch retraction is an exit device feature that pulls the latch back electrically, so the door opens without anyone pushing the bar. PDQ's MLR uses a quiet motor to retract the latch on 6300 and 6400 exit devices in about 300 milliseconds. With continuous power it holds the latch back for electronic dogging, and it pairs with low energy power operators. People inside can always exit by pushing the bar.

What is the difference between fail safe and fail secure?

Fail secure hardware stays locked when power is lost, and fail safe hardware unlocks. The PDQ MR199, GT199 and 6W99 trim are field changeable between the two, and the 6W99 ships fail secure. Fire-rated doors must stay latched in a fire, so an electric strike on a rated door must be fail secure. Check your local code for stairwell and egress doors.
