3. Setup and Installation
3.1. Components Overview
- ABS plastic siren base
- Centering bulb
- Inner and outer covers (varnished ABS, pearlescent or metallic colors)
- LED flasher (smoked dome)
- Double magnetic reed tamper switch (anti-opening and anti-tear)
- Electronic circuit board (SMD technology, resin-immersed)
- Battery housing (for 12 V 2.2 Ah battery, battery not included)
3.2. Mounting the Siren
- Select a suitable mounting location, ensuring it is secure and provides optimal sound coverage.
- Open the siren casing by disengaging the tamper switches.
- Use the ABS plastic siren base as a template to mark drilling points on the wall.
- Drill holes and secure the siren base to the wall using appropriate fasteners.
- Ensure the centering bulb is correctly positioned.
3.3. Wiring and Power Connection
- Connect the 12 V DC power supply to the designated terminals. The electronic circuit is protected against polarity reversal.
- Install a 12 V 2.2 Ah battery (not included) into the battery housing. Ensure correct polarity.
- Connect the control wires for activation. The siren supports 2 or 3-wire activation and programming for positive or negative control.
- Connect the ON-OFF installation signaling wires (for permanent or timed signaling).
- Verify all connections are secure and correct before proceeding.
3.4. Programming
The MURANO-LS siren offers flexible programming options:
- Control Input: Program for positive or negative control signals.
- Activation Mode: Choose between 2-wire or 3-wire activation.
- Sound and Timing: Select from 4 distinct sound programs and timing configurations.
- Alarm Cycles: Configure for 4 daily alarm cycles or infinite cycles.
- Refer to the detailed wiring diagram (not provided in this manual, typically found in a separate installation guide) for specific programming jumper or switch settings.
4. Operating Instructions
4.1. Initial Power-Up
- After completing installation and wiring, apply 12 V DC power to the siren.
- The siren will perform an automatic test of the speaker and battery efficiency.
- Observe the LED flasher for initial status indications.
4.2. Alarm Activation
When an alarm signal is received from the control panel (via the programmed 2 or 3-wire input):
- The siren will activate, emitting the pre-programmed sound.
- The LED flasher will activate, providing visual indication of the alarm.
- The flasher includes an alarm memory function, indicating if an alarm occurred even after it has ceased.
4.3. Siren Failure Output
The siren provides an output signal in case of a siren failure, allowing it to be connected to a control panel for remote monitoring of its operational status.
5. Maintenance
- Regular Cleaning: Periodically clean the exterior of the siren with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Check: The siren performs an automatic battery efficiency test. If a battery fault is indicated (e.g., via the siren failure output or specific LED patterns, refer to your control panel manual), replace the 12 V 2.2 Ah battery with a new one of the same specifications.
- Tamper Switches: Ensure the double magnetic reed tamper switches are clean and free from obstructions to guarantee proper anti-opening and anti-tear protection.
- Visual Inspection: Regularly inspect the siren for any signs of physical damage, loose connections, or environmental wear.
- Professional Inspection: It is recommended to have the siren professionally inspected and serviced by a qualified technician at least once a year.
