Installation Instructions 
1. INTRODUCTION 
The MCS-720 is a fully supervised wireless siren, for indoor use, that 
communicates with PowerMax Pro or PowerMaxComplete alarm system.  
Features 
• The siren is activated according to specific commands that are 
transmitted from the alarm system (refer to the alarm system 
specifications - SIREN SIGNALS). 
Note: The siren is activated for a predefined "Bell Time" (refer to 
PowerMax Pro / PowerMaxComplete installer guide, par. 4.4), 
according to local authorities requirements, or until the system is 
disarmed, whichever occurs first. 
•  Squawk indications when using a keyfob 
High, mid or low siren squawk (beep) sound can be used to 
indicate arming (1 squawk) and disarming (2 squawks) of the alarm 
system. 
•  Flash lights / strobe 
When an identified activation command is received from the alarm 
system, the strobe light is activated every 1 second (100ms ON, 
900ms OFF) for a period of 20 minutes maximum, or until the alarm 
system is disarmed whichever occurs first. There is an option to 
disable the lights/strobe locally by using an internal jumper. 
•  Tamper protection 
The unit has tamper protection for wall and front cover opening 
alarm. 
•  Low battery voltage alert 
When the battery voltage is low, 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. 
•  2-way full supervision 
The siren is a fully supervised, 2-way communication device. It 
includes a receiver, to receive activation commands 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 installer 
guide, paragraph 5.2 – Diagnostic Test). 
•  Self-test feature 
The siren can be tested locally (by using the SELF TEST switch) or 
remotely (from the control panel), upon batteries insertion, prior to 
the actual wall installation.
