Q: AC is fuse blowing on a PS914 when AC power is applied.
A: If AC fuse blowing on a PS914 power supply then the mother board is defective. You need to replace the power supply with a new one.
Q: Are the PS914 and PS873 option boards interchangeable?
A: The optional boards for PS914 and PS 873 are not interchangeable.
Q: How many EL devices can be operated from the PS 914?
A: You can operate two EL devices with PS914-2RS, up to four with PS914-4RL and up to eight with PS914-4RL-4RL with limited distance from power supply to the EL devices.
Q: How many Chexit devices will the PS 914 operate?
A: Chexit devices shipped after 8-24-2015 with motor driven:
You can power up to four Chexit devices per PS914 power supply.
0-200' run wire, use #18 gauge.
0-500' run wire, use # 14 gauge.
Chexit devices shipped prior to 8-24-2015 with solenoid driven:
You can power up to four Chexit devices per PS914 power supply on low traffic doors.
0-100' run wire, use #14 gauge.
0-200' run wire, use #12 gauge. Q: Can 240 VAC be applied to the PS900 power supply?
A: The standard PS900 series power supplies can be powered with 120-240 VAC.
Q: What would make the PS914-2RS cycle on and off?
A: Followings could cause the PS914-2RS power supply to cycle on and off:
Wrong gauge wire or run distance from power supply to the EL device. Click HERE for wiring requirements.
Over load to the DC output.
Defective potted module.
Defective EL solenoid.Q: Is the the PS914 EL wiring adapter needed for Von Duprin Chexit device?
A: The EL Wiring Adapter is not needed for a CX device.
Q: My PS914 has power but my 2RS card is not working?
A: The following could cause the 900-2RS board not to operate:
If 900-2RS board is not plugged into the PS914 mother board.
If PS914 power supply is selected for 12VDC instead of 24VDC.
If control contact such as card reader is not providing closure contact between SC and I1 or SC and I2, the outputs will not provide voltage to the electric exit device.
Defective 900-2RS board. Q: Does the PS914-2RS x EL device have time delay?
A: The PS914 x 900-2RS option board doesn't have time delay. If time delay is required specify PS914 x 900-4RL. 900-4RL provides up to 75 seconds, 5 second increment unlock time.
Q: Are the batteries for the PS 914 BBK the same as the ones from the 873 BB?
A: The battery for the PS873 and PS914 are the same, 7AH sealed Lead Acid battery.
Q: Can Battery Backup (BB) be added to a PS900 series power supply in the field?
A: Battery backup can be added to the PS900 series power supplies. Order the 900-BBK as seen here:

to get the battery backup board and batteries for field installation.
Q: Why would the horn sound when the solenoid tries to engage on a Von Duprin Chexit device?
A: Make sure the proper power supply (PS873 or PS914) and proper gauge and run wire is used for Chexit devices shipped prior to 8-24-2015 with solenoid driven.
Q: What do I need to use a fire alarm board with a PS914?
A: The Basic PS914 power supply will not accept a 900-FA fire alarm board.
900-8F option board is required with PS914 power supply to accept 900-FA fire alarm board (900-8F is an adaptor board for 900-FA).
900-FA fire alarm board plugs into 900-8F option board.
900-8F option board plugs into PS914 power supply. Q: What size wire and run is recommended when using a PS914-2RS?
A: For Product Shipped Prior to August 2012 using the old (black) potted module:
0-100 ft 14 gauge wire 0-200 ft 12 gauge wire
For Product Shipped After August 2012 using the new PWM (clear):
1. For EL 98/99 or 33A/35A Rim Devices:
0-500 ft 12 Gauge Wire
0-300 ft 14 Gauge Wire
0-200 ft 16 Gauge Wire
2. For all other 98/99 or 33A/35A device types:
0-250 ft 12 Gauge Wire
0-150 ft 14 Gauge Wire
0-100 ft 16 Gauge Wire Q: What is the warranty on a power supply?
A: The warranty on the PS900 Schlage Electronics Power Supplies is 12 months from date of manufacture. The warranty is only valid for a true manufacturing defect in the power supply. Any customer damage to the power supply will void the warranty.
Q: How many times can an EL device be operated when using a PS914-2RS with battery backup?
A: The Von Duprin PS914-2RS retracts the EL or QEL device approximately 200 times with five second hold time after each pull.
Q: Please send me a typical wiring diagram for a PS914 and an El x 99 exit device.
A: Here is a typical wiring diagram for a PS914 and an El x 99 exit device:
