Let me get this straight: You do not have a doorbell chime in your house, so you want to use the security system to do the chime?

Yes. Also, there's more than just a chime (I could've stated that this is just an example in my first post), If you take a look at the link which leads to SmartHome's website showing the Insteon-compatible Elk M1 Gold, there's a capability for creating Whenever/And/Then rules such that when the doorbell button gets triggered, I can perform one of the tasks depending on the condition. For example:

<pre>WHENEVER Doorbell (Zn 1) BECOMES NOT SECURE
AND Apartment (Area 1) IS ARMED STAY
THEN ANNOUNCE Guest Has Arrived (Task 6)
THEN ACTIVATE Guest Has Arrived (Task 6)
WHENEVER Doorbell (Zn 1) BECOMES NOT SECURE
AND Apartment (Area 1) Is ARMED AWAY
THEN ANNOUNCE Occupants N/A (Task 5)
...</pre>

This is all typed and copied from the demo version of Elk-RP software. Also, as to the "Apartment," the Elk M1 Gold is only for temporary installations, as there are DIY users over at forum.homesecuritystore.com who uses a component-based security systems instead of all-in-one (keypad, dialer, etc. built into one security system) security system, like PowerMax+, Honeywell Ademco Lynx, etc.

As an addition to the rules that I mentioned above, I can have Elk execute a group (which can be called a "scene") to adjust the level of lights, turn on the 120V bed vibrator (connected to the Insteon ApplianceLinc module) for few seconds, and then when I open the door, slightly brighten up the lights, and so on and so forth.

So anyway, I wanted to get the wireless doorbell receiver connected to the security system. Is there anything I can do in order to connect to a security system (mainly zones that take place of the speaker terminals that go out to the doorbell receiver's speaker? Do I need a relay for that? I believe the relay is supposed to open the circuit when it gets a signal from the doorbell receiver, am I correct?

<b>For example:</b>
<list><li>I press down the button in the wireless doorbell transmitter, which then sends the signal to the wireless doorbell receiver through RF.
<li>When the receiver receives the signal from the transmitter, the receiver sends the signal from the positive terminal to the relay's + side. (But in the receiver side, I'll have to shorten out the resistor and add a 100uF capacitor in order to provide about 3v of electricity to the relay, correct?
<li>If the relay receives a ignal a 3v, the relay opens the circuit, which then trips the zone and that the security system can handle the rest, like performing automated tasks to alert someone inside the premises of a visitor/guest.
<li>When the zone is secure (in other words, no signal is sent from the wireless doorbell receiver), the relay returns to the "closed" state, indicating that the relay receives almost close to 0v.
</list>

Now, what happens if I connect a wireless doorbell receiver directly to a control panel's zone terminals (let's say "Zone 1")? If there's no wire that shorts out the resistor and no 100uF capacitor, how will a control panel behave?

Am I making any sense now?

Oh, know what? I read the Installation manual for Elk M1 Gold, and it has support for an analog zone type. So, I don't need a relay and a transistor.

What I can do is connect a doorbell to Zone 1 and setup the rules for the zone. Here's an example: Whevenever every 3 seconds and doorbell (zone 1) is greater than analog value 1.3 volts and the security system (apartment) is armed in stay mode, ...well, you get the ideal, like announcing a task and activating it... :p I could set the timer to one second, but then the statements next to "then" gets triggered like twice. So with 3 seconds, I think it'll be fine.

But then I don't have a voltmeter, and so when I purchase Insteon-compatible Elk M1 Gold, I think I'll get it all figured out.
