Paradox SR250 Wireless Siren with Built-In Strobe Light
Introduction
The SR250 is a weatherproof, stand-alone, fully supervised outdoor wireless siren with a built-in strobe light and wireless transceiver. It utilizes 2-way wireless communication for continuous supervision between the panel and siren, responding to alarm signals within four seconds. Its robust construction allows reliable operation from -30 °C to 50 °C (-22 °F to 122 °F) when using alkaline batteries or a power supply. Under normal use, the SR250 can function for up to 3 years without battery replacement, with battery life extended by using an optional AC or DC power supply. This guide details the installation and configuration of the SR250 wireless siren.
Installation
Only qualified personnel should install, operate, maintain, and repair this equipment.
- Record the serial number (located on the back of the unit) and the installation location of the SR250 for later reference in the Paradox BabyWare software.
- Loosen the four screws on the siren cover and remove it.
- Loosen the four screws on the PCB cover and remove it.
- Screw the SR250 siren onto the wall using the five provided holes (four for the wall and one for the Tamper Spacer).
- Ensure the Tamper switch is screwed onto the wall through the Tamper Spacer.
- Batteries:
- If batteries are already installed: Remove the plastic tab between the top battery terminals and the battery compartment. Leave the cover off until the siren is learned.
- If batteries are not installed: Insert batteries, ensuring correct polarity. Leave the cover off until the siren is learned.
Note: It is recommended to replace batteries every three years to prevent leakage.
- After programming the siren (refer to the Programming section), reinstall the PCB cover.
- Reinstall the top cover.

Upgrading Firmware
Firmware for the SR250 can be upgraded using Paradox InField software (V5.5.9 or higher) and the 307USB Direct Connect Interface. The SR250 must have batteries installed to upgrade firmware.
Note: Ensure the SR250 is awake before upgrading. To wake the siren, press the Learn switch (#9 in Figure 1). A 60-second delay allows the update to begin.
- Remove the front cover and the PCB cover.
- Connect the 307USB to the InField connector (#4 in Figure 1).
- Follow the firmware upgrade instructions available at www.paradox.com > Software > InField Firmware Upgrade Instructions.
Tamper Supervision
If a tamper condition is detected, the SR250 will sound an alarm and the strobe light will flash for 4 minutes. The control panel will adhere to the global supervision options set within the panel.
