Door Holder Extension Kits

Description

The Edwards 1500 Series Door Holder Extension Kits are used

where it is desired to hold doors open and where a standoff dis-

tance between the magnet assembly and the armature base is re-

quired. The extension rod kit can be used with Edwards 1504,

1505, 1508 and 1509 Series Door Holders. Parts from these door

holders are used with the extension kits to form a complete unit.

Installation

Insert the extension rod into the armature base and secure

with #10-32 x 1 1/2" (38 mm) armature securing screw

(Figures 1 - 3).

d. Insert spherical bushings (supplied) and flat washers

(supplied with 1500-7 and 1500-12 only) into the

extension rod assembly as shown in Figure 2 or Figure 3,

as applicable. Secure catch plate in extension rod using

#10-32UNF x 1" (25 mm) securing screw (Figure 2).

For adjustable units only, adjust the extension length by

loosening the knurled locking nut, extending the rod to

the desired length and retightening the knurled locking

nut (Figure 2).

NOTE: Proper alignment of the catch plate and the

electromagnet helps ensure sufficient holding force.

Align the catch plate with the electromagnet by moving

the extension arm up or down and back or forth while

simultaenously adjusting the catch plate against the

magnet. There should be no gap between the catch plate

and the magnet.

g. After the desired extension length and contact alignment

have been achieved, perform the following (Figure 2):

1. Using a 5/32" (4 mm) Allen Wrench (supplied), lock

the extension arm into position by tightening the

armature securing screw (Figure 2).

Do not

overtighten.

h. Perform an operational check of the Electromagnetic

Door Holder as outlined in the installation instruction

provided with the door holder.

2. For more detailed information on installation of the door

holders, see the instructions supplied with the door holder.

WARNING

The extension kits project a significant distance from
the doors they are mounted on and should, therefore,
be mounted as high as possible to preclude interfer-
ence or personal injury.

1. Install the extension kit as follows.

Remove the #10-32 x 1 1/2" (38 mm) armature securing

screw and remove the catch plate from the armature base

(Figure 1).

Insert spherical bushings (removed in Step 1.a) as shown

in Figure 2 or Figure 3 as applicable. If bushings are

damaged, replace with bushings supplied with the door

holder extension kit.
