![]() Continuous green LED on the base indicates power supply form the panel.The unit emits 2 rapid beeps to indicate that it has reset to standby mode. Red LED on the alarm cover will flash every 10 seconds to indicate that it is in ‘Hush Mode’ and will automatically reset after approx 10 minutes. Also operates ‘Hush’ feature to silence nuisance alarms. Manual ‘Test/Hush’ button provided to test alarm circuitry, sounder, relay and activate all interconnected alarms in the system.to select ‘Resistive Mode’ select jumper S2 to the ‘R’ position (this connects 22kOhm resistance in series with the ‘C’ terminal and relay and 68kOhm resistance between ‘C’ and ‘NC’). Unit is supplied in the ‘No Resistance Mode’. To select ‘Pulse Mode’, set jumper S1 on the circuit board to ‘P’. ![]() Unit is supplied in the ‘Continuous Mode’. (Normally Open, Normally Closed, Common) Continuous Mode, or pulse mode (switches for seconds only) options, selected by installer. The Volt-free contacts are rated at 30V DC, 1 Amp. Relay: Operates on panel power supply and also on battery back-up power supply.Interconnectable with up to 20 Ei181, Ei184 and Ei186 smoke and heat alarms.Additionally, soldered contacts are used in order to eliminate failures due to corrosion and arcing that are associated with commonly used pressure contacts. The diameter of the piezo disc in the sounder measures 35mm, and is securely held will silicone mastic to prevent creepage and premature horn failure. Encased horn assembly gives a minimum sound output of 85dB(A) at 3 meters.Low battery warning – single bleep every 40 seconds. ![]() ![]() Battery is monitored for open/short/high impedance.
