DELIVERY MODE. The Delivery mode requires a key to open the door without the alarm activating. No time delay on open door. Alarm automatically arms when door is closed. Without a key, the alarm activates, siren sounds when the door is opened. Alarm continues until the door is closed when siren turns off and the alarm resets. For the Delivery mode, J4 is down.

2-MINUTE DELIVERY MODE. This fourth mode permits the door to be opened and remain open for up to two minutes without the alarm activating. If the door remains open for more than two minutes, the alarm activates and the siren sounds. Alarm resets when door is closed.

DOOR AJAR MODE. The Door Ajar mode does not require a key to enter or exit. There is a settable length time delay from 15 seconds to a maximum of two minutes. If door remains open past time delay, the alarm will sound until the door is closed. When the door is closed, the unit rearms. For the Door Ajar mode , J4 is down to accommodate the non-latching alarm.

In addition to the operating modes, the Alarm Lock PG21MSS can be configured to an “On/Off” and a Back Door Annunciator mode. When PG21MSS in the “On/Off” mode and disarmed with a key, the unit will beep for two seconds each time the door is opened.

Door alarms are designed to be installed onto the interior (secure) side of the door opening for both access and egress control. To resist unauthorized egress, the PG21MSS tamper protection sounds the alarm if there is an attempt to remove the cover or the entire unit. To control the operation of the door alarm and for tamper protection, a mortise cylinder is installed into the cast housing cover. For applications where exterior access is required, the PG21MSS can accommodate a rim cylinder.

The Alarm Lock PG21MSS can be installed onto single or double, inswing or outswing doors. The PG21MSS Door Alarm can be mounted onto the door or jamb and the magnetic actuator installed onto the opposite side of the gap. If additional features will be included, for example a door bell, consider mounting the unit onto the jamb.

For the purpose of this article, we will install an Alarm Lock PG21MSS Pilfergard Door Alarm to control a double door using the provided magnetic actuator. The double door is the shipping entrance for the warehouse. During working hours, the door will be opened in order for merchandise to be brought in and out. The door alarm will be installed onto the secured side of the door, using a 1” mortise cylinder to control operation.

Step 1. Disconnect torsion spring to set the Alarm Lock PG21MSS in the “On/Off” mode.

Step 2. Determine the location for the door alarm.

Step 3. Position the provided template onto the door and door jamb. The template is two-sided. One side is for outswinging single doors and the other side is for all other configurations. The outswinging single door applications require the magnetic actuator be placed farther away to accommodate the arc of the door alarm, while still being close enough to operate.

Step 4. Use an awl or similar tool to locate the four baseplate mounting holes. Draw a vertical line for the magnetic actuator.

Step 5. Drill the four 1/8” diameter holes – one inch deep.

Step 6. Remove the baseplate from the door alarm.

Step 7. Install the baseplate using the four provided screws.

Step 8. Install the 9 volt battery.

Step 9. Determine the location for the magnetic actuator by setting the Reed Selection Jumper. The Reed Selection Jumper is located directly beneath the terminal strip on the circuit board. The default setting is to enable the right reed switch when looking at the circuit board. This is the left side when the housing cover is mounted onto the baseplate.

Step 10. Depress the clear button, located at the bottom left corner adjacent to the jumpers. The clear button resets the system to the Magnetic Alignment mode. The Magnetic Alignment mode is used to align the magnetic actuator.

Step 11. Place the unit onto the baseplate by first hooking the housing cover onto into the clip at the bottom. Then tilt the housing cover onto the baseplate. Use one of the short mounting screws to keep the cover in place.

Step 12. Place the magnetic actuator against the lower edge of the housing cover that has the activated reed switch.

Step 13. Slowly slide the magnetic actuator along the side on the drawn line until the LED on the front of the housing cover lights.
