OEM Audible Alarm Component | Replacement Siren for Compatible Detex Exit Control & Alarm Devices

Restore the audible warning function of compatible Detex exit-control hardware with the Detex PP-5966-1 Piezo Horn.

This genuine Detex replacement component serves as the siren / audible alarm element inside compatible Detex alarm assemblies. When the associated exit-control device is activated, the horn produces the audible warning used to alert personnel that the protected opening has been operated.

Detex factory parts documentation identifies the PP-5966-1 as the siren component within the siren-switch assemblies used in compatible ECL-230D and ECL-600 devices.

Genuine Detex Replacement Siren

The PP-5966-1 is not a complete exit alarm.

It is the individual siren component used within a larger Detex alarm assembly.

For example, Detex's ECL-230D factory parts breakdown identifies the siren-switch assembly as including:

• Switch assembly

• 9V battery connector

• PP-5966-1 siren

• Switch-actuator holder replacement kit

This makes the PP-5966-1 ideal when the existing alarm mechanism is functioning but the audible horn itself has failed.

Compatible Detex ECL-230D

Detex's current ECL-230D parts list identifies:

Item 2c – PP-5966-1 – Siren

The horn is part of the ECL-230D's 100069 siren-switch assembly.

This allows technicians to replace the siren separately instead of replacing the entire exit-control lock when the remaining components are still serviceable.

Compatible Detex ECL-600

The current Detex ECL-600 parts list also identifies:

PP-5966-1 – Siren

as part of the device's 100069 Siren Switch Assembly.

Audible Alarm Function

The PP-5966-1 provides the audible warning generated by the compatible Detex device when the associated alarm circuitry is activated.

Typical applications include alerting facility personnel to:

• Unauthorized use of an emergency exit

• Operation of a protected exit door

• Activation of compatible Detex exit-control hardware

• Security-related door activity

The horn itself does not determine when the alarm sounds. Activation is controlled by the compatible Detex switch, electronics, and door hardware.

Service & Replacement Applications

Replace the PP-5966-1 when the existing horn has been properly diagnosed as:

• Silent during alarm activation

• Intermittent

• Damaged

• Producing weak or unreliable sound

• Electrically failed

Before replacing the horn, confirm that the problem is not caused by:

• Dead or disconnected battery

• Damaged wiring

• Failed switch

• Battery connector

• Alarm-control circuitry

• Poor electrical connection
