PARADOX SR250 Wireless Siren w-Built-In Strobe Light
SR250 Wireless Siren w/Built-In Strobe Light
Introduction
The SR250 is a weatherproof, stand-alone, fully supervised outdoor wireless siren with built-in strobe light and wireless transceiver. The SR250 uses 2-way wireless communication, which provides continuous supervision between the panel and siren with fast response to alarm signals within four seconds. With its tough weatherproof construction, the SR250 operates reliably from -30 ºC to 50 ºC (-22 ºF to 122 ºF) when using alkaline batteries or power supply.
With normal use, the SR250 will function up to 3 years without the need to replace the batteries (battery life can be extended by using an optional AC or DC power supply). This guide describes how to install and configure the SR250 wireless siren.
Overview

| 4 | Infield connector |
| 5 | Dual-action tamper switch (detects when cover is removed and when unit is removed from wall) |
| 6 | Strobe lights |
| 7 | Antenna (Can be extended using an RG6 or RG59 coaxial cable with standard male F connectors. Attach the antenna using a female/female F adapter) |
| 8 | Status and Signal Strength LEDs |
| 9 | Learn switch |
Installation
Only qualified persons should install, operate, maintain, and repair this equipment.
- Write down the serial number (on the back of the unit) and location of the SR250 for later reference, to insert into the Paradox BabyWare software.
- Loosen the four screws from the cover from the siren and remove cover.
- Loosen the four screws from the PCB cover and remove.
- Screw the SR250 siren onto the wall through the five provided holes (four wall and one Tamper Spacer).
- Ensure that the Tamper switch is screwed onto the wall through the Tamper Spacer.
- Batteries:
- If the siren already has batteries installed:
- Remove the plastic tab between the top battery terminals and the battery compartment
- Leave the cover off until you learn the siren
- If the siren does not have batteries installed:
- Insert the batteries – ensure correct polarity
- Leave the cover off until you learn the siren
Note: We recommend replacing the battery every three years to avoid leakage.
- If the siren already has batteries installed:
- After programming the siren (see Programming section): Reinstall the PCB cover.
- Reinstall the top cover.

Upgrading Firmware
Upgrade SR250 firmware through the Paradox InField software (V5.5.9 or higher) using the 307USB Direct Connect Interface. The SR250 requires the batteries installed in order to upgrade the firmware.
Note: Ensure that the SR250 is awake before upgrading the firmware. To wake up the siren: press the Learn switch (see #9 in Figure 1). The siren provides a 60 second delay in order to begin the update.
- Remove the front cover as well as the PCB cover.
- Connect the 307USB to the InField connector (see #4 in Figure 1).
- Upgrade according to the firmware upgrade instructions: Go to www.paradox.com > Software > InField Firmware Upgrade Instructions.
Tamper Supervision
If a tamper is detected, the SR250 will sound an alarm and the strobe light will flash for 4 minutes. The control panel will follow the global supervision options set in the panel.
