RCI 8371 Installation Manual

I N S T A L L A T I O N
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.
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.
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.
RCI also carries a full line of switching devices and other accessories to interface with the
8300 series electromagnetic locks.
