Inovonics EN1941 One-Way Binary RF Module
Description
Inovonics EN1941 One-Way Binary RF Module
The Inovonics EN1941 one-way binary RF module provides reliable low-cost, low-power wireless communication for integrators, making virtually any binary switch device wireless. The EN1941 is a universal one way RF module with two alarm input pins, allowing the use of dual inputs. This module can be used for any applications such as call notification and any switch or alarm conditions that need to be transmitted wirelessly.
Product Features:
* Easy to integrate
* Low current draw
Product Specifications:
* Dimensions: 6.4 x 3.3 x 1.3cm
* Power requirements: Requires an external power supply (Vcc) of 2.6 to 5.5 volts; voltage must be sustained at 2.6 volts or above and supply 100 milliamps during the transmit cycle
* Current draw: EN1941: Assuming check-in messages every three minutes and infrequent alarm messages (one per day, on average), the average current draw is 32 uA;
peak current draw while transmitting is less than 100 mA; one alarm/restore cycle per hour results in about 15 uA increase in average current EN1941-60: Assuming check-in messages every sixty minutes and infrequent alarm messages (one per day, on average), the average current draw is 5 uA; peak current draw while transmitting is less than 100 mA; one alarm/restore cycle per hour results in about 15 uA increase in average current
* Input requirements: Open: When an active source (open collector or dry contact) is used to drive the alarm or tamper input, the voltage should be between 0.75xVcc and Vcc; a passive input should have an impedance of greater than 5.1k ohm between the input and ground. Closed: When an active source is used, the voltage should be less than 0.25xVcc; a passive input should have an impedance of less than 240 ohm
* LED requirements: The LED output is an active output from the microprocessor, with a 1k series resistor to limit current draw; default state is low, and the LED pin is pulled high during transmit
* Operating environment: Temperature: -4 to 140°F (-20 to 60°C), Humidity: Up to 90% (non-condensing)
* EchoStream® frequency: 902-928 MHz, frequency hopping spread spectrum
* Check-in time frequency: EN1941: 3 minutes; EN1941-60: 60 minutes
* Regulatory compliance: FCC, RoHS, UL 639, UL 1076, UL 1610, ULC-S306, ULC/ORD-C1076, ISED, RCM; EN1941-60: also includes UL 25601
