EASY TO INSTALL. The liquid-tight 2″ NPT tank mount is adjustable by hand. Simply loosen the nut and slide the alarm to the depth you want. Other mounting hardware available if needed.
Battery powered so it can be located anywhere, instantly.
When there is a high or low level condition, the buzzer sounds and the beacon LED will flash. In the default mode, the user presses the button to silence the buzzer, and the LED continues to flash as a reminder. The 101 dB buzzer has a unique warbling sound cuts through factory noise so it will be heard.
Different behaviors are field-selectable using DIP switches on the circuit board. Choose from:
- 30-minute snooze alarm, (on/off)
- tank filling mode (where it shuts off LED and buzzer until the next fillup)
- auto/manual reset after level corrected
- relay N.O./N.C.
- relay output delayed 15 minutes
Battery Power is uninterruptible and allows installation anywhere. No outlets, electricians, or inspectors needed. The Lithium batteries included and have a shelf life of 20 years. A 2400mA-hr capacity combined with smart software allows these to sound for 25 days straight! In typical situations the batteries will last for many years. When the batteries do run low, a unique low-battery signal is given. (different from the level alarm signals) Batteries are user-replaceable in the hazardous location.
Durable Aluminum electronics enclosure.
Pipe and float switch are 316 stainless steel construction. There is even a SS float guard available to protect the float switch for applications where the alarm is being moved frequently.
Harsh Weather rated temperature range is +60ºC to -40º C. [140ºF to -40ºF]
Reversible float switch. SS and BUNA floats are reversible. Specify preferred orientation in the order box. You can always reverse the float later.
Grounding lug is included on stainless steel units.
Optional Relay Output for connection to safe areas through an I.S. barrier.
Choice of materials: stainless steel or PP pipe, with float switch in BUNA, PP or PTFE.
Stainless pipe and float
Stainless pipe and BUNA float
Polyproplyene pipe/PP float
For applications where the alarm is frequently removed from tanks or drums the guard prevents damage to the float. Secures to the pipe with set screws.
A relay output for signals sent to an approved I.S. barrier. 80mA max. 10ft cable is standard.
A 2″NPT stainless steel plug welded to the pipe. Sealed. Depth is not adjustable.
Extra cable length over the standard 10ft length. Heavy 0.032″ jacket for superior durability. Stranded conductors x 24 gage, shielded.
Additional Replacement Battery
This is the only battery that is certified for use with GIZMO I.S. alarms. One is included with the purchase of each tank alarm.
