1. Call24 Mark III February 11 2011 8 Tamper Detection Call Type 6 When the tamper switch is activated by severe vibration or if the security current loop circuit is opened via any of several series connected normally closed switches or if the nightlight is removed the controller will initiate a call as described above This call type would typically be programmed for Quiet Mode which sets the front panel LEDs and front panel speaker to be disabled during call activation It would also be programmed for Auto Activate so that after the ANI and voice messages have been sent the unit would enter Talk mode immediately Quiet mode would still be in effect once the unit entered Talk mode so that Listen could be activated without alerting anyone in the vi cinity applies to radio only telephone operation is inherently in Listen mode due to the full duplex nature of the call If an Activation code is received it will turn off Quiet Mode and allow security to have 2 way communications with the call box There are three tamper inputs to the controller One is a vibration sensor the second is a circuit that senses the removal of the nightlight and the third is a current loop circuit that must be a closed circuit for a no alarm condition A mercury tilt switch door ajar or any other normally closed switch may be con nected into this loop where any opened switch anywhere in the loop will acti vate the tamper alarm To disable the tamper alarm2.

8. CALL24 Mark III Callbox User Manual September 2007 Overview This device is used as an emergency communications call box for remote areas such as parking lots walkways or other locations not having easy access to telephone lines Communications from the call box to security personnel is done via two way radio or cellular phone To use the user presses a call button on the front panel which causes the unit to activate a strobe light and send one prerecorded voice message to the caller and another voice message to security The message to security would typically state the nature of the call and the lo cation of the call box while the message to the caller might state that the call is underway Security responds by sending a coded signal back to the call box to enable it for two way communications with the caller Once enabled the call box button becomes a push to talk switch allowing the caller to talk directly to security When a cell phone is being used the call box becomes totally hands free When communications have ended security can send another coded signal to the box to re arm it for another emergency call and deactivate the strobe Many of the features of the callbox described here are programmable by the factory and or dealer Technical Summary Hardware Components The Software Idle Mode Call Initiation Call Progress Radio Call Progress Phone TEST Pushbutton Call Type 5 Tamper Detection Call Type 6 Low Battery Call T
