The Alarm Lock PG30MB Pilfergard Keypad-Controlled Door Alarm is a heavy-duty, battery-operated commercial security device designed to monitor emergency exits, service entrances, and restricted-access doors while providing powerful audible notification of unauthorized openings.

Featuring a 95 dB-class electronic siren, built-in digital keypad, three programmable security levels, magnetic door monitoring, and remote alarm relay output, the PG30MB provides flexible door security for commercial, industrial, and institutional facilities.

Part of the Alarm Lock PG30 Series, this microprocessor-controlled alarm combines advanced programming capabilities with simple surface-mounted installation. The device is designed for standard commercial openings and narrow-stile aluminum storefront doors.

When the system is armed, opening the protected door activates the alarm according to the programmed security level and delay settings. The integrated keypad allows authorized personnel to arm, disarm, reset, and manage the alarm without requiring a separate mechanical cylinder.

For installations requiring keypad operation from the opposite side of the opening, the optional Alarm Lock PG30KPD Remote Keypad provides additional control.

Finished in Metallic Bronze, the PG30MB complements dark bronze aluminum storefronts, commercial doors, and architectural hardware.

How the Alarm Lock PG30MB Works

1. System Arming

Authorized personnel enter the programmed Master Code to arm the alarm. The device begins monitoring the protected opening using its magnetic door contact.

2. Continuous Door Monitoring

When the door is closed and the magnetic actuator is properly aligned, the system monitors the opening for unauthorized activity.

3. Unauthorized Door Opening

If the door is opened while armed, the PG30MB activates the selected alarm sequence. An optional entry alarm delay may apply if enabled.

4. Audible Security Notification

The electronic siren sounds using the programmed sweep, steady, or pulsing pattern.

The Form-C relay can simultaneously signal compatible external monitoring equipment.

5. Authorized Passage

An authorized Passage Code allows permitted use of the door according to the selected security level.

Depending on programming, the alarm can automatically restore monitoring when the door closes.

6. Alarm Reset

Authorized personnel can silence or reset the alarm using a programmed Master or Management Code.

Battery Life and Power Requirements

The Alarm Lock PG30MB uses a standard 9V alkaline battery for standalone operation.

The manufacturer provides estimated battery life based on the number of alarm activations and the selected alarm shutdown settings.

Examples with the two-minute shutdown setting include:

Alarm Activations Per Year	Estimated Battery Life
1	17.6 Months
3	17.1 Months
5	16.6 Months
7	16.1 Months
10	15.4 Months

The manufacturer also specifies approximately three hours of continuous alarm operation under its stated test conditions.

Actual battery performance will vary based on usage, battery quality, and operating conditions.

For installations requiring continuous power, the optional Alarm Lock PP100 Power Supply or another compatible 9–12VDC, 500mA supply may be used.
