| | The ELK-930 performs three functions. It can detect ring activation from one or two doorbell buttons and a single telephone line. It conveniently isolates the voltage and current and produces an open collector (pull to ground) output which can be used to trigger an automation controller, relay, timer, etc. The circuit is pre-scored so that the individual detectors may be snapped off (separated) from each other.
The ELK-930 Doorbell Detector monitors the current draw of a doorbell and produces an open collector output when the pushbutton is pressed and the doorbell draws 900mA or more. This open collector output can be used to trigger an automation controller input that utilizes high to low switching (pull to ground) for activation. The ELK-930 Telephone Ring Detector monitors the voltage on the telephone line and produces an open collector output (pull to ground) when the telephone ringing voltage is approximately 50 Volts or greater. The output follows the ringing pattern.

| | The Mini-Clik II rain sensor is a simple, but effective way to prevent your sprinklers from coming on during or after rainfall. Based on our patented design, the Mini-Clik II is the most reliable and accurate rain sensor in the world. Each unit is constructed of high inpact thermoplastic and aluminum for years of trouble-free operation, even under harsh conditions. Simple click-stop settings accurately measure rainfall in quantities of 1/8" to one inch and shut off the system when turf has received the rainfall it needs. Reset rate is adjustable.

507-381BW
SPDT Reed Switch |
|
- Form C contacts (also known as SPDT).
- Make gap: 5/8"
- Break gap: 1 1/4"
- Max 30VDC 30VAC .25A 3W
| | Most reed switches are "normally closed" (the switch is closed when the magnet is near the switch.) Most security systems are wired with normally closed reed switches. Normally open switches are a bit more complicated to make, are a bit more expensive, and are normallynotused with security systems.
Normally open reed switches are useful for automation tasks. Connect the 507381BW to a PF284 PowerFlash controller and send a command to turn on a light when the garage door is open, or connect the 507381BW to home automation controllers such as
ActiveHomeor
HomeVision.
