Description

The Altronix SMP3 is an auxiliary power supply that can be used to power alarm devices if your alarm control panel does not have enough auxiliary power output. The SMP3 converts low voltage AC power input into a selectable 6VDC, 12VDC or 24VDC power output with a continuous power supply current of 2.5A. The power supply also has a charging circuit with a maximum charge rate of 350mA so that you can connect a backup battery such as the Ultratech 1240. With a battery back up connected, the SMP3 will automatically switch to standby backup battery continue to work during a power outage.

You can use the the ‘SW1’ and ‘SW2’ switches on the SMP3 power supply to choose the output voltage your alarm installation requires. With ‘SW1’ closed (ON) and ‘SW2’ open (OFF), the SMP3 has an output voltage of 6VDC. With ‘SW1’ open (OFF) and ‘SW2’ open (OFF), the power supply has a 12VDC output voltage. Finally with ‘SW1’ open (OFF) and ‘SW2’ closed (ON), the SMP3 power supply has an output voltage of 24VDC. When using the 6VDC or 12VDC output voltage, you should use an AC transformer with an output voltage of 16.5VAC, 40VA such as the Honeywell 1361. If you use the SMP3 with the 24VDC voltage output, you will need a 28VAC, 100VA transformer.

The Atronix SMP3 also has convenient LED diagnostics to provide visual indication of how the power supply is operating. With the red (DC) LED on and the green (AC) LED on, the power supply is working properly. With the red (DC) LED on and the green (AC) LED off, the power supply has no AC power and the backup battery is supplying power. With the red (DC) LED off and the green (AC) LED on, the SMP3 has no DC output due to a short circuit or thermal overload condition. Finally, with both LEDs off, there is no DC output or AC input because the unit is discharged and the battery is dead or not connected.

There are (6) terminals along the bottom of the SMP3 power supply. The (2) terminals on the left side are for (+) and (-) DC which you will use to connect to your alarm device. The middle (2) terminals are for (+) and (-) BAT and you should connect the red battery lead to the BAT (+) terminal and the black battery lead to the BAT (-) terminal. The other end of the battery leads have spade connectors which slide onto the battery terminals on the Ultratech 1240 sealed lead acid battery. Finally, the last (2) terminals marked ‘AC’ are for connecting your AC transformer.

We recommend home runs but you can technically "daisy chain" them as long as they are in parallel with proper polarity. Terminal 3 is positive and terminal 4 is negative.
Thanks Frank, that's what I thought and that's how I have the keypads connected. Do you see a problem, connecting one siren to another, (daisy chaining) and not connecting both sirens to the panel separately with their own wire run?
The strobe/sirens use the bell output (terminals 3 and 4) which support up to 2A (2000mA) so those are fine and completely isolated from constant keypad power. The keypads will connect on terminals 4 and 5 and will sum up to 320mA leaving you with 280mA available for other devices such as motion detectors, glass breaks, wireless receivers, alarm communicators, etc. The key here is the concept of the bell output being isolated from keypad power and therefore siren/strobes are not involved in that power calculation.
Hi Frank, it's been a couple years since I installed the system I purchased from you. I am upgrading the system. My question is power needs. The keypads are (160ma active & 40ma Stand by). I have 4 strobe/sirens (180ma each Total = 720ma) I also have 2 strobes only (120ma each). Assuming both keypads are active (160ma and not 40ma stand by) the total will be 1160ma. Will the VISTA-21iP power all those devices? Also, the terminals are getting pretty cluttered, see picture. Any advice on the connections or just make them all fit? Finally, can I daisy chain 2 of the strobe/sirens, meaning connect 1 strobe/siren to the control pannel and the 2nd one to the strobe/siren? Thanks!
The left DC terminals go to your powered device (i.e. motion or glass break). You will need to run a jumper between the DC negative on the SMP3 and your ECP ground on terminal 4 on the VISTA-21iP. That is the only connection to the panel. Only the power connections on your security device will land on this aux power supply. The data connections will connect to the zone terminals on the VISTA-21ip. Then you will need to program the zone that those physical data connections are allocated to.
The SMP3 states that you connect the 2 left terminals to your alarm device. (Is the alarm device the strobe lights & siren or the control panel)? Then the 2 middle terminals attached to the battery & the 2 right terminals attached to the transformer. How does this connect to the Vista 21ip? I will also be installing a wireless module, where does this get connected for power? Thanks!
