INSTALLATION

8371/8372

Electromagnetic Locks

Instructions

1. Please read template mounting instructions and use template that is provided for installing the

electromagnetic lock.

2. Connecting wire should be of sufficient gauge to prevent line loss.

3. The 8371/8372 electromagnetic lock requires either 12 or 24 VDC for correct operation.

The voltage is jumper selectable. (See Fig. 1)

For 12-volt operation two jumpers are used; contact pins one to two and three to four are jumpered.

For 24-volt operation only one jumper is used; contact pins two to three are jumpered. Note:

The 8371/8372 is shipped with jumpers installed for 24-volt operation.

12 or 24 VDC Supply

Connect the positive (+) lead from the power supply to TB1-1. Connect the negative (-) lead from the power supply

to TB1-2. For wiring installation, refer to Figure 1.

4. Do not tighten the armature plate tightly against the door. The armature plate must remain movable to

allow surface alignment with the magnet face. The magnetic lock will lose holding force without this

floating alignment.

5. Do not trim the rubber washer mounted on the head of the armature center bolt.

Trimming this rubber washer will adversely affect the operation of the electromagnetic lock.

Optional LSS

(

Lock Sensor Status Remote Indication

)

Magnet Locked – When the magnet is locked, the common contact (TB1-3) and the normally open contact

(TB1-5) are closed. The normally closed contact (TB1-4) would be open.

Magnet Unlocked – When the magnet is unlocked, the common contact (TB1-3) and the normally closed contact

(TB1-4) are closed. Note: The LSS relay contacts are rated 24 VDC @ 1 amp maximum.

The optional LSS includes a local Light Emitting Diode (LED) indication: no LED – no power;

red LED – lock is unlocked; green LED – lock is locked.

Switching Accessories

RCI also carries a full line of switching devices and other accessories to interface with the

8300 series electromagnetic locks.

Secondary diode installed Remove (not necessary).

LED status incorrect Misalignment of armature plate Check to see that alignment agrees with template.

To Ensure Instant Magnetic Release

• Wire the DC filtered power to the line side of the power switch to avoid simulated delays on unlocking.

The local “ON/OFF” switch must be wired between the DC source voltage and magnet, as shown below.

• All solid state switches or switching devices must be installed between the DC power source and the

positive (+) line of the magnetic lock.

Note: All RCI magnets have MOV surge suppression as a standard feature.Additional suppression (i.e., diodes) may cause a delay in release.

Maintenance

Contacting surfaces of the electromagnetic lock and armature plate must be kept free of contaminating

materials. Surfaces should be cleaned periodically with a non-abrasive cleaner.

We recommend all mounting fasteners be inspected/tightened regularly to prevent them from loosening

through normal vibration of the door and frame.

RCI offers a full line of listed power supplies, switching devices and other accessories to interface with

the 8300 series electromagnetic locks.

NOTE: 8300 series electromagnetic locks should be powered with filtered and regulated UL listed

power supplies.

Voltage

These locks are now shipped with the default voltage set for 24VDC. If you need to change the voltage to

12VDC, see detailed instructions included.This change was made to prevent damage to the lock when

24VDC is applied with the jumpers set to 12VDC.

Anti-Tamper Screws

We are currently shipping 8371 and 8372 Electromagnetic Locks with new anti-tamper screws installed in

the front face of the housing. These screws, when in place, prevent the insertion of an Allen wrench into the

mounting screw openings on the underside of the lock. These screws will need to be removed prior to

installing the lock so as to allow the mounting plate to be removed from the top of the lock. The cavity

cover screw needs to be removed to access the security screw on the right hand side, while the screw on

the left is clearly visible on the face of the lock.
