Elk Training, Week 1

RELAYS


What is a relay?
Relays are like a light switch on your wall – the light in your room is powered, but waiting for the switch to turn it on. When you flip the switch, the light turns on.

When would you use one? For security, automation, or access control application requiring devices such as strobes, siren drivers, lights, long range radios, garage doors, audibles, timers, etc. These devices already have power to them and can be turned on by the relay when the control, or other electronic devices, trigger the relay. They are usually triggered to coincide with another event, or it reaches the programmed time set in the control.

What makes Elk relays different? Elk relays have the highest contact rating in the industry. Why is that good? The higher the contact rating, the greater the range of devices you can control. Most relays available in the security market are great at controlling low voltage devices, but our higher contact rating means you can switch standard lighting and other high voltage devices, as well as the traditional low voltage devices. Elk 912, 912B, & 924 relays have a contact rating of 7 Amps @ 30 VDC and 10 Amps @ 120VAC.

Which one will do the job?
If size is a consideration, the Elk-912 is the smallest on the market and operates @ 12 VDC. If you need a little more versatility, the Elk-912B operates on 12 or 24 VDC. If you want to trigger something off of a status light (LED) from a keypad or motion, or anytime you have limited current, try the Elk-924 Sensitive Relay. It only requires 1 mA trigger and operates on 12 or 24 VDC.
