MCS-730 
Fully Wireless Outdoor Siren 
Installation Instructions 
 
1. INTRODUCTION 
The MCS-730 is a fully wireless outdoor siren, designed for 
installation in areas in which wiring action is difficult or impossible. 
The siren is compatible with PowerMax control panels such as 
PowerMax Pro, PowerMaxComplete, PowerMaxExpress or newer 
panels (not compatible with PowerMax and PowerMax+ control panels).  
Features 
•  Siren and strobe light activation: When an identified event 
message is received from the compatible PowerMax alarm system, 
the siren activates its sounder & strobe light. 
 Notes: 
  The sounder is activated for a predefined "Bell Time" (refer to 
PowerMax Pro / PowerMaxComplete / PowerMaxExpress installer 
guide, par. 4.4), according to local authorities requirements, or until 
the system is disarmed, whichever occurs first. 
  The strobe light operates (every 1 second) during the "Bell Time" + 
20 minutes or until the system is disarmed, whichever occurs first.  
•  Tamper / supervision failure indication: In case of tamper or 
supervision failure (loss of communication with the alarm system), 
the siren transmits the message to the alarm system and then the 
alarm system determines whether the siren should be activated or 
not. If the siren does not receive an acknowledge from the alarm 
system, the siren will function independently.  
•  Low battery voltage alert 
When the battery voltage is low, a low battery message is sent to 
the alarm system. After the low voltage message delivery, at least 2 
siren alarms are possible before the siren is totally inactive. 
•  Power Supply Options: Non-rechargeable battery. Optional - two 
non-rechargeable batteries.  
•  Sound Types: Burglar (between 1400Hz - 1800Hz), Fire, squawk. 
•  Squawk indications: Squawk (beep) sounds can be used to 
indicate alarm system arming (1 squawk) and disarming (2 
squawks) by a keyfob (squawk can be enabled from the PowerMax 
User menu). 
•  Strobe Light Color: The siren can be purchased with red, blue, 
amber or transparent lens, according to the desired strobe light color.  
•  Siren activity LED: A flashing LED (optional, at the bottom of the 
siren front panel) indicates siren activity (can be disabled by an 
internal jumper, see fig. 3, step 8) 
•  Double Tamper protection: When the siren front panel is 
removed or when the siren is removed from the wall, tamper alarm 
is sent to the alarm system.

Fig. 1b – Mounting Position 
IMPORTANT! The MCS-730 siren must be installed on the wall in a 
vertical position with the screw pointing to the floor only
, as illustrated 
in Figure 1b. The importance of correct positioning of the MCS-730 is 
to enable the siren to function as a waterproof device. 
•  2-way full supervision 
The siren is fully supervised, 2-way communication device. It 
includes a receiver, to receive event messages from the alarm 
system, and a transmitter, to periodically transmit its status signal 
to the alarm system. 
The transmitted signal strength can be measured during the 
installation (refer to PowerMax Pro / PowerMaxComplete / 
PowerMaxExpress Installer guide, par. 5.2 – Diagnostic Test). 
•  Self-test feature 
Upon pressing the self test switch, siren functional check is performed - 
low level sounds and flash light indicate that the siren is serviceable.

Interference Prevention 
This device complies with FCC Rules Part 15. Operation is subject 
to two conditions: (1) This device may not cause harmful 
interference, and (2) this device must accept any interference that 
may be received or that may cause undesired operation. 
The digital circuit of this device has been tested and found to comply 
with the limits for a Class B digital device, pursuant to Part 15 of the 
FCC Rules. These limits are designed to provide
 reasonable protection 
against harmful interference in residential installations. This equipment 
generates, uses and can radiate radio frequency energy and, if not 
installed and used in accordance with the instructions, may cause 
harmful interference to radio and television reception. However, there is 
no guarantee that interference will not occur in a particular installation. If 
this device does cause such interference, which can be verified by 
turning the device off and on, the user is encouraged to eliminate the 
interference by one or more of the following measures: 
–  Re-orient or re-locate the receiving antenna. 
–  Increase the distance between the device and the receiver. 
–  Connect the device to an outlet on a circuit different from the one 
which supplies power to the receiver. 
–  Consult the dealer or an experienced radio/TV technician. 
Changes or modifications not expressly approved by Visonic Ltd.
