DESCRIPTION

The PG21 is a microprocessor-controlled door alarm for surface mounting on a door or door frame. Typical applications include emergency fire escape doors, nursing home stairwell doors, rear restaurant and theater doors. The PG21 is designed to continually monitor the status of a door. When opened, the protected door triggers an alarm sounder, an optional strobe or can activate another device via a Form-C relay. It has various programmable features including:

•Four Siren Sounds

•Four "Alarm Modes" for a variety of applications (see page 5).

•Programmable Time Delays

•Battery Operated (Battery life approximately 2 ½ years)

•External Power Supply Capability

•Built-in Door Bell (Requires button installation)

•Cover Tamper Protection (Unauthorized removal trips alarm)

•"Key Lock Tamper" (Cover cannot be removed without key)

•Accepts standard mortise cylinders

•Multiple Door Monitoring (External Reed Switch Contacts)

•Form-C Relay (Connect to fire/burglary panel or other device)

•Annunciator Feature (Beeps when door opens)

•Two Operating Modes: "Always Armed" and "On/Off"

•Strobe Feature (PG21MSS models only)

•Status Indicator

The PG21 unit is usually mounted on the interior of the door frame or door and is paired with a magnet (Magnetic Actuator) mounted on the opposing side of the door gap. Opening the door, when armed, will activate the alarm. The PG21 is shipped from the factory in "Always Armed" mode (if key is removed, unit automatically re-arms) and can be converted to a manual "On/Off" mode (allowing the operator to manually arm or disarm with the key). The Status indicator (located on the front of the Housing Cover) signifies whether the unit is armed or disarmed (red indicates armed status). A selectable annunciator feature beeps to signal the opening of the door while the unit is disarmed.

A. INSTALLATION: PRELIMINARY STEPS

Installation is divided into 5 main steps: (A) Preliminary, (B) Wiring, (C) Configuration, (D) Mounting and (E) Testing.

1.Choose a suitable location. Most often, the PG21 is mounted on a door, and the Magnetic Actuator is mounted to (or inside) the door jamb. However, if the PG21 will have a doorbell or any external wiring, give careful consideration to the mounting location and make allowances for all necessary wiring. For example, if you wish to monitor multiple doors, choose a generally central location as wires (and reed switch contacts) will need to run to all doors in series. If you mount the PG21 on a door, the Baseplate must be mounted far enough away from the edge of the door to prevent unit from striking the door jam when opening the door.

2.Examine the enclosed template. The two-sided template provides mounting hole locations (drawn in solid circular lines) for several door types. Use the four corner holes for the Baseplate as shown on the template. Note: Certain narrow-stile doors require only two holes for the Baseplate.

3.Mark and drill holes (use 1/8" bit, 1" deep) on the door and jamb as per the template directions. Hole locations are drawn in solid circular lines.

4.External Wiring. Mark and drill the hole (shown on the template) for external wiring such as doorbell, reed switch or relay wiring.

5.Knock out the necessary holes from the Baseplate and install on the door with the supplied #8 sheet-metal screws.

6.Temporarily mount the Housing Cover into the Baseplate to aid in positioning the Magnetic Actuator location. Mount as follows: Remove all keys from cylinder (thus ensuring the cylinder is in a 12:00 position). Hold the Housing Cover vertically with the inside facing toward you (the PC board and jumpers can been seen at bottom), slide the switch to the right. (Note: Each time the Housing Cover is removed, the switch MUST be moved to the right before mounting). Hook the Housing Cover into the clip at the bottom of the Baseplate, then gently snap the top of the Housing cover into the top of the Baseplate. DO NOT FORCE. Note: If the switch is in the wrong position (not moved to the right), or if a key is accidentally left inside the cylinder, the Housing Cover is specifically designed NOT to lock into the Baseplate.

7.Position the Magnetic Actuator as indicated by the red sticker on the side of the Housing Cover. If stickers were removed, use the Magnet Alignment Mode (see page 3) or place the Magnetic Actuator 1½ " from the bottom edge of the Baseplate. Mark holes and (as with the Baseplate) use a 1/8" (0.125") bit, and drill the hole 1" deep.

8.Install the Magnetic Actuator with the supplied #8 sheetmetal screws (1"). Be sure to insert the Magnet (P1358) and Magnet Cover (P0291) into the Magnet Housing (P0290) before mounting.

B.WIRING

External wiring to the PG21 requires that the unit be mounted on the frame with the magnet on the adjacent door. (The PG21 may be mounted on a door with the addition of a Model 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). Terminal 1 = Normally Closed; Terminal 2 = Common; Terminal 3 = Normally Open. On alarm, the relay will activate and remain latched for as long as the sounder is on.

Reed Switch (Terminals 4 & 5). Connect external reedswitch 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 series as shown below in Figure 2, several doors may be monitored simultaneously. Using #22AWG wire, maximum wiring distance should not exceed 50 feet. Note: When external 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 supply: positive (+) red to Terminal 7; negative (-) black to Terminal 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 J14 located in the center of the PC board (see Fig 5b, page 4). Note: J14 (Pin1) is the external Strobe Power (9 volts) and J14 (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 Configuration 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 converted 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 Torsion Spring must be disabled--disconnected from the Cam Assembly. To disable the Torsion Spring, use a small screwdriver and unhook the end of the Torsion Spring from 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").

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 page 5 and decide which options should be selected for your application.

1.Connect the battery; a chirp will sound ensuring that power is properly connected. Important: Press the small CLEAR button at the lower-left corner of the circuit board (see Figure 4 below).

J7-Alarm LongDelay 60 Sec.:	Disabled	Enabled*
J8-Annunciator (Beep):	Disabled	Enabled
J9-Annunciator Volume:	Low Volume	High Volume

*NOTE: If Jumpers 6 and 7 are both enabled, Alarm Delay = 2 minutes

Important: The jumpers are only read at startup and whenever the unit is armed. If the jumpers are changed after power up, the unit must be rearmed before the jumper changes take effect. In addition, the unit will not function unless Tamper Screw (SC543) is in place.

J1: Siren. Factory default sound is a Sweeping Siren. Jumper moved to the "lower" position (near the edge of the circuit board) produces a Steady-Tone Siren.

J2: Pulsing Siren. Default setting is Constant-ON. Jumper moved to the "lower" position produces a siren that "pulses" on and off.

J3: Siren 2-Minute Timeout. Default setting (jumper at "upper" position) enables the timeout, allowing the siren to turn off two minutes after the alarm is tripped--if

door is closed within that two minute period. Jumper moved to the "lower" position disables the timeout, keeping the siren on until manually reset. To indicate that an alarm has occurred (Alarm Memory), the LED will start flashing. Alarm Memory is cleared after approximately 4 hours or by rotating the lock cylinder counter-clockwise and removing the key. Note: If the door is still open after two minutes, the alarm will restart.

J4: Security Level. Default setting (jumper at "upper" po- sition--High Security) enables a latching alarm when tripped--siren remains on for 2 minutes or until turned off by the key (turn key to the left). Jumper moved to the "lower" position will set the lower security nonlatching "Door Ajar" alarm mode--siren turns on when door is open, and turns off (and resets) when door is closed.

Jumpers 5-7: These jumpers are used for doors that are intended for authorized entry and exit, providing an "Arming/Exit" delay time when exiting, and an "Alarm/Entry" delay time when entering. Disarming with the key within the programmed time will prevent an alarm. See descriptions for J5 and J6 below for specific examples. Note: If jumpers J6 and J7 are both moved to the "lower" position, the result is a delay of 2 minutes.

J5: Arming/Exit Delay. Default (jumper at "upper" position) provides no Arming/Exit Delay. Jumper moved to the "lower" position enables a fixed 15-second "Arming/Exit Delay", allowing exit without alarm (i.e. the time between turning the key to the left and when the system actually arms). For example, if J5 is at the "lower" position, the protected door can be used as an "exit door"---first, insert and turn metal key to the left, then open door, exit, and let the door close. When the delay expires, the PG21 re-arms.

J6: Alarm/Entry Delay. Default (jumper at "upper" position) provides no delay. Jumper moved to the "lower" position (near the edge of the circuit board) provides 15 seconds of Arming Delay time. If jumpers J6 and J7 are both enabled, the result is an Alarm Delay of 2 minutes. For example, if J6 is at the "lower" position, the protected door can be used as an "entry door"---

first, open the door from the outside, insert and turn metal key to the left, and let the door close. When the delay expires, the PG21 re-arms.

J7: Alarm/Entry Long Delay. Default (jumper at "upper" position) provides no delay. Jumper moved to the "lower" position selects 60 seconds of Arming Delay time. If jumpers J6 and J7 are both moved to the "lower" position, the result is an Alarm Delay of 2 minutes.

J8: Annunciator. The annunciator provides a 1 second "beep" sound. The jumper in the factory default position (jumper at "upper" position) disables the "beep". Jumper moved to the "lower" position selects the "beep" sound when the door is closed and unit is disarmed. Note: This jumper selection will operate only if the PG21 is mechanically configured to "On/Off" mode (see page 2, Section "C", "CONFIGURATION").

J9: Annunciator Volume. The jumper in the factory default position (jumper at "upper" position) produces a low volume beep. Jumper moved to the "lower" position (near the edge of the circuit board) produces a high volume beep.
