Wireless Sounder Instructions

Introduction
RISCO Group's two-way External Wireless Sounder is designed to extend the
signaling capabilities of RISCO Group's wireless systems. The wireless sounder
offers an easy and flexible solution for quick installation. The sounder is powered by
its own batteries and communicates wirelessly with the security panel.
Up to 3 wireless sounders can be assigned to a system.
Operational Functions
Alarm / Tamper Indication
Upon an alarm condition, the sounder will be activated for a period of time defined
by the system (Bell Time Out parameter).
Low Battery Indication
Upon a low battery condition a trouble indication is sent to the panel.
There are 2 types of low battery indications:
 Radio low battery
 Speaker low battery
Supervision
Each sounder can be defined to be supervised by the panel. The system generates
a local fault signal identifying the sounder whose signal is not received during a
predefined time, followed by a report to the Alarm Receiving Center (if defined).
Pre Alarm Indication
When an entry time starts, the system transmits a pre-alarm signal to the sounder.
If the system is unset before the entry delay time expires, a cancellation signal is
sent to the sounder.
If the sounder does not receive a cancellation signal within the entry delay time, the
sounder will be activated.
Sounder Self Testing
Once placing all batteries in the battery holders or pressing on the reset switch
located on the PCB (with the tamper switch open), the sounder performs a
functional self test indicated by a strobe flash squawk sound.
LED display
The wireless sounder has 2 LEDs located on the PCB. These LEDs are
enabled when the tamper is open and 10 minutes after the tamper is closed.
Red: Indicates transmission
Yellow: Indicates a low battery
Red and Yellow (3 seconds): Confirms successful learning
