MCS-730/MCS-730 AC
Fully / Mains Powered Wireless Outdoor Siren 
Installation Instructions 
1. INTRODUCTION 
The MCS-730, powered by 1 or 2 (optional) non-rechargeable batteries, 
is fully wireless outdoor siren, designed for installation in areas in which 
wiring action is difficult or impossible. It is compatible with control panels 
such as PowerMax Pro, PowerMaxComplete, PowerMaxExpress or 
Visonic newer panels (not compatible with PowerMax+ and PowerMax 
control panel). 
The MCS-730 AC is similar to MCS-730 but It is powered by an External 
9VAC Adaptor and non-rechargeable backup battery - enables very 
long operation time without replacing the battery. The MCS-730 AC 
complies with PowerMax+ also. 
Features 
•  Siren and strobe light activation: The siren produces a strong 
alarm noise and emits flashing light to deter intruders and guide 
police to the site. 
 Notes: 
  The duration of the siren's alarm is controlled from the control panel 
by setting the "Bell Time" option (refer to alarm system installer 
guide, par. 4.4) and should be set according to local authorities 
requirements. 
  The strobe light operates (every 1 second) for 20 minutes after 
siren stops or until the system is disarmed, whichever occurs first. 
•  2 Types of alarm indication 
The siren produces different alarm signals for Burglar and Fire. 
•  Squawk indication: 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 control 
panel User menu). 
•  Tamper / supervision failure indication: Siren is equipped with 
tamper protection, which produces alarm if a burglar attempt to 
open the siren's cover or remove siren from wall. 
•  Low battery voltage alert 
The siren reports a low battery message to the alarm system when 
battery is about to drain. After low voltage is reported, at least 2 
siren alarms are possible before the siren is totally inactive. 
•  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)

Fig. 1b – Mounting Position 
IMPORTANT! The MCS-730/MCS-730 AC 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/MCS-730 AC 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 
periodically transmits its status signal to the alarm system. 
•  Installation diagnostics 
The transmitted signal strength can be measured during the 
installation (refer to the alarm system Installer guide, par. 5.2 – 
Diagnostic Test). 
•  Self-test function 
Upon pressing the self test switch, siren functional check is performed - 
low level sounds and flash light indicate that the siren is serviceable.
