User manual ELK PRODUCTS ELK-155RT

[. . . ] The ELK155RT may be customized by use of removable on-board jumper plugs. For example: our MilliMiserTM option allows the already low current draw of the ELK-155RT to be reduced even lower. The stainless steel exterior reflects the color of the mounting surface allowing the ELK-155RT to blend easily with any residential or commercial building. FEATURES ! [. . . ] WHITE (Burglary BA+): Connect to the positive (+) 12 VDC Burglary alarm output terminal. NOTE: This input utilizes our ComboTriggerTM feature which automatically recognizes the difference in a steady voltage or a pulsing voltage from the control's alarm "bell" output. If the input voltage is steady the Yelping siren and Burglary voice message will play. If the input voltage is pulsing (1/2 to 1. 5 second intervals) the Bell sound and the Fire message will play, provided the Red wire is connected to a constant +12 VDC source as explained below. The ELK-155RT is ideal for controls which have only a single alarm "bell" output. ORANGE (Fire FA+): Connect to the positive (+) 12 VDC Fire alarm output terminal. Note: It may not be necessary to connect this wire if the control panel can pulse the alarm "bell" output for a fire alarm condition. Refer to the instructions for the White and Red wires for more information. RED ( 12 Vdc +): OPTIONAL Connection of this wire to a positive (+) 12 VDC constant power source allows use of the steady/pulse ComboTriggerTM feature by supplying standby current to the microprocessor in the ELK-155RT. NOTE: Most of the operating current will also be drawn from this wire, therefore the power source must be capable of providing up to 2 Amps of current. It may be necessary to connect this wire directly to the standby battery. If so we recommend using an in-line fuse holder with a 2 Amp fuse for overcurrent and short circuit protection. GREEN (BA -): OPTIONAL Some controls, (DSC & others) switch on and off the negative (-) side of the alarm output instead of the positive (+). Simply connect the Green wire to the negative (-) 12VDC Burglary alarm output terminal, the Red wire to the positive (+) alarm terminal, and the black wire to the common negative (-) terminal of the control. When connected in this manner, this input will also activate the Fire channel message if the alarm output is pulsed on/ off in 1/2 to 1. 5 second intervals. NOTE: The ELK-155RT Siren is factory set for maximum loudness and current draw. [. . . ] Repeat 5. Move the siren/speaker from its hanging position to its final mount by aligning it's top and bottom slots with the 1/2" tabs on the top edge of the backplate and in the bottom center above the bolt threads. Lift up to engage the tabs in the cover with the two "U" shaped slots on the top edges of the backplate. Thread 1/4-20 hex bolt into hole on bottom of cover and tighten until secure. [. . . ]
