Use Electric Strike Simulator
Use the Electric Strike Simulator (p/n 259-506) to test voltage and current sensors on ESID. If readings are
less than indicated here, replace 9V battery in simulator and retest.
Current Test
To test for current at normal levels:
1. Thread one lead wire through current transformer.
2. Clip ends of lead wires together to make one loop.
3. Move simulator switch to "current" and press test button.
4. Watch screen and lights above display on strike system.
• Three or four lights should turn on.
• Current "A" should show 30-50% in display.
To test for current at strike levels:
1. Put two or three loops through current transformer.
2. Follow steps above to test.
3. Display should show the following:
• All lights should turn on.
• Alarm and strobe should turn on.
With two loops,
• Current "A" should be 80-110%.
• Strike indication might go on and off.
With three loops,
• Current should be 130-160%.
• Strike indication should be continuous.
