Mechanical Configuration; Jumper Configuration - Alarm Lock PG21 Series Installation Instructions Manual

(P1358) and Magnet Cover (P0291) into the Magnet
Housing (P0290) before mounting.
B. WIRING
External wiring to the PG21 requires that the unit be mount-
ed on the frame with the magnet on the adjacent door. (The
PG21 may be mounted on a door with the addition of a Mod-
el 271 Flexible Cable). All wiring is made at its terminal strip.
Wiring connections are summarized in the Wiring Diagram
shown below in Figure 1.
Relay (Terminals 1-3). Ter-
minal 1 = Normally Closed;
Terminal 2 = Common; Termi-
nal 3 = Normally Open. Note:
Regardless of jumper settings
(see below, "Jumper Config-
uration"), the strobe
equipped) and relay output will
always turn off in 1 minute.
Reed Switch (Terminals 4 &
5). Connect external reed-switch contacts to Terminals 4
and 5 and remove reed selection jumper W1 located in the
center of the PCB. Note: If reed switches are wired in se-
ries as shown below in Figure 2, several doors may be mon-
itored simultaneously. Using #22AWG wire, maximum wir-
ing distance should not exceed 50 feet. Note: When exter-
nal reed switches are used, the internal reed switches must
be disabled by removing the reed selection (W1) jumper.
Power (Terminals 6 & 7). Connect an external power sup-
ply: positive (+) red to Terminal 7; negative (-) black to Ter-
minal 6. Leave in the internal battery as a backup battery. If
using the Alarm Lock PP100 Power Supply, connect the two
battery clips to the unit and the internal battery as labeled.
Doorbell (Terminal 8). Connect between terminal 8 and 6

using momentary-on switch to activate Doorbell. Produces
alternating tone. Will not operate during Alarm or during
Arm delays. Note: Do not use a lighted door bell button--
the light will drain the battery.
Strobe Connector (Jumper 14). If using a Strobe unit, run the
wires through Strobe Assembly and Palnut and plug female
polarized connector into JP1 located at the top right corner
of the PC board (see Fig. 6b, page 4). Note: JP1 (Pin1) is
the external Strobe Power (9 volts) and JP1 (Pin2) is the
Strobe Ground.
The Strobe and siren are on the same circuit, therefore the
timeout duration is the same for both.

C. CONFIGURATION
There are two configuration sections: Mechanical Configu-
ration and Jumper ("Software") Configuration.

Mechanical Configuration

You must decide if the PG21 lock will be kept in its original
factory configuration (in "Always Armed" mode) or convert-
ed to a manual "On/Off" mode.
The PG21 is shipped from the factory with a Torsion Spring
(HW1149) installed (see Figure 7, page 7) which forces the
Cam Assembly (HW1187) against the PC Board switch,
thus keeping the lock Armed whenever the key is removed.
If you wish to convert the lock to On/Off mode, allowing

the Cam Assembly to be moved in either position, the Tor-

+ sion Spring must be disabled--disconnected from the Cam

the Cam Assembly, as illustrated in the following images:
Note: To allow for future re-conversion, the Torsion Spring
can be simply disconnected and not removed (see Fig. 3c
below).
See the following three images (Figs. 3a-3c) to help you
convert your PG21 from "Always Armed" to "On/Off" mode,
or to restore your PG21 back to its original factory condition
("Always Armed").

Figs. 3a-3c: Disconnect Torsion Spring from Cam Assembly:
Fig. 3a displays the Torsion Spring as it is installed from the factory (thus
"Always Armed" mode). To convert to "On/Off" mode, first lift leg of the
Torsion Spring (Fig. 3b) from Backplate, then unhook other end of spring
from Cam, releasing tension (Fig. 3c), and allowing Cam to move freely.

Jumper Configuration

Before configuring the jumpers, also see pages 5-6 and de-
cide which options should be selected for your application.
1. Connect the battery; a chirp will sound ensuring that
power is properly connected.
2. Reed selection jumper W1 is located in the center of
the PCB. The jumper should be set to the side of the
unit that will have the magnet installed (see Fig. 5).
