Pros/Cons of speaker vs siren for output2

[WayneW]

What are the pros & cons of using a speaker versus a siren for use on an M1 output2 (exterior use)?
I realize that using a speaker makes this a non-UL installation and I am OK with that.

speaker advantage: interior & exterior sounds are in sync, not clashing (i have heard this is true, but haven't verified) Is this even worth worrying about considering I hope it doesn't go off very often?

questions:
Does the exterior speaker ever talk? what does the exterior speaker do while the interior speaker is talking? go silent? keep sirening?

How much power/current does the speaker draw? It is impossible to off-load the output2 speaker to a different power supply, whereas the siren(s) can be easily controlled by a relay & powered from an aux power supply.

How loud are the exterior speakers, such as the Elk-44 or Elk-SP40? Does it lose significant volume if you use two speakers?

The Output 2 siren output does not talk. It is intended for usage primarily outside where talking is not needed.

Siren volume in an 8 ohm speaker is a function of the speaker size and the amount of power you can run through it. The M1 has a single transistor on the Output 2 siren output. You can switch a relay and use an aux power supply to add a 4 transistor siren driver or high power self contained siren/speaker like the ELK-100 or SS-30. The siren driver with one speaker will draw about 1.25 amps. Add another 8 ohm speaker to the ELK100 and it will draw about 1.75 amps at 12VDC.

Some of the piezo sounds draw alot less current and are ear piercing at close range. The frequency is pretty high. For the siren sound to carry a long way, you need a lower frequency siren sound.

Output 2 on the M1 can be delayed before it comes on to allow any false alarms generated by the home owner to be disarmed before the neighborhood is alerted.

What does the exterior speaker (output2) do while the interior speaker (output1) is talking? go silent? keep sirening?

How much power/current does using a single speaker such as the Elk-44 draw from the system? I am trying to determine if using output2 to drive a speaker uses more or less system power than a siren (which typically seems to be on the order of 1 amp). In other words is the power draw on the 1 transistor built-in M1 siren driver similar to the Elk-100 4 transistor siren driver?

Does the M1 support the ComboTrigger feature of the Elk-100 siren driver or the Elk-45 siren?

When output2 is configured for voltage, does it pulse for fire and constant on for burglary? Or is it always constant on (when in alarm)?

What about for interior? I am in the process of wiring my house, and will have speakers all over inside. Do I need to wire for sirens too?

What does the exterior speaker (output2) do while the interior speaker (output1) is talking? go silent? keep sirening?

The exterior speaker is synchronized to the inside speaker on siren sounds. It continues to run when the inside speaker is talking phrases.

The siren driver on the M1 output 2 is a single transistor driver and will draw less than 1/2 of the current of the ELK100 siren driver: about 1/2 amp into an 8 ohm speaker.

Does the M1 support the ComboTrigger feature of the Elk-100 siren driver or the Elk-45 siren?[

When output2 is configured for voltage, does it pulse for fire and constant on for burglary? Or is it always constant on (when in alarm)?

Output 2 has temporal pulsing for fire and yelping for burglar. There is an option for industrial buzzer sound. Output 2 does not have volume control like Output 1 has. The sound that is triggered will be the highest priority sound. Fire sound will take precidence over burglar sound if both are triggered at the same time.

What voltage equals temporal pulsing? What voltage equals yelping? What happens if I have output2 connected to a relay controlling a siren or a strobe?

bump... Spanky?

The temporal coded siren output for output 1 and 2 is activated when any fire alarm activates. Otherwise, the regular siren sounds or the industrial buzzer if its option has been selected.

It output 2 is selected as a DC switch to ground, output 2 will pulse the 1 second temporal coded pulses for fire and steady output for all other alarms.

Temporal code for fire is 1 second on, 1 second off, 3 times. Then a 4 second delay. That might not be the exact spec., but it is something like that.
