As a subcontractor I can install all the wiring you need as well as the best ETL/UL 1449 4th Edition surge suppression designed specifically for fire alarms. There are many off the shelf surge suppression, but none quiet like the Lectra-Shield surge suppressor. Even the box, is a useful design preventing a feed back loop up case ground. Part number LS-E120HWCP20CB. This product is a true in series protector because there is only one way you can install it. If you install it backwards the power will not go through. If you have reverse polarity, the power will not go through. The safety features on this thing is awesome, even comes with a 20 amp over current fuse It also carries a 5 year warranty and is repairable. FA series low voltage surge suppression FA 30VB for SLC, zones, and dry contacts FA30BH for NAC circuits as well as noisy lines. Simplex, Edwards and other panels may need higher operating voltage for their low voltage FA 60VB for SLC, zones, and dry contacts FA 60NC for NAC and noisy circuits FA90V for audio and noisy circuits as well. DLTTOS200V for phone lines and noisy circuits. Spike Block is a ground filter that prevents lightning from penetrating the case ground of the panel. It works well with the LS-E120HWCP20CB. |
